Wyoming DOT Wins Environmental Award for Bridge Project

The Wyoming Department of Transportation recently received a 2022 Environmental Excellence Award in the category of Ecosystems, Habitat, and Wildlife from the Federal Highway Administration for its role in the Snake River Bridge reconstruction and wildlife crossing integration project. The award is one of 14 conferred by FHWA nationwide in various environmental categories.

Wyoming DOT – along with the Wyoming Game and Fish agency, Teton County, and other community organizations – designed a project for the replacement of a critical bridge on Wyoming Highway 22 over the Snake River, near Jackson, and expanded it to accommodate local and migrating wildlife within the Greater Yellowstone National Park ecosystem.

FHWA cited Wyoming DOT’s exemplary “achievement and extensive stakeholder collaboration, community engagement, and environmental considerations” in granting the award.

The wildlife underpasses and three additional wildlife crossings built by this project should provide for “safer movements”, especially for large animals such as moose, elk, and deer. 

The agency is also implementing additional improvements that will enhance recreation and natural resource education in the nearby Rendezvous Park with work that will include increasing wetlands along ponds, constructing a boardwalk, and making a swimming hole deeper. 

Construction on this project should begin in the spring of 2023, Wyoming DOT noted.

This follows a joint effort by Wyoming DOT and the Wyoming Game and Fish agency launched in 2019 that committed a combined $2.5 million toward installing wildlife crossings along US 189 in southwest Wyoming – known as the “Dry Piney” project – to help reduce wildlife-vehicle collisions.

The purpose of the improvements is to support positive public interaction with the natural environment while addressing the needs of the ecosystem, noted Wyoming DOT Director Luke Reiner in a statement.

“We appreciate the recognition and affirmation from the FHWA that this is a special project that will benefit not just the transportation of motorists but of wildlife, too,” said WYDOT director Luke Reiner. “I am grateful to our partners who were instrumental in shaping this project into an award-winning success.”

State departments of transportation in many parts of the country are working to improve wildlife crossings across a variety of transportation projects.

For example, the Colorado Department of Transportation and the Colorado Parks and Wildlife agencies completed wildlife underpasses along a rural stretch of Interstate 25 between Colorado’s two largest cities, Denver and Colorado Springs, in October 2021.

That wildlife mitigation system is part of a $419 million transportation improvement project – known as the I-25 South Gap project – that aims to improve safety and travel on 18 miles of I-25 south of the Denver metropolitan region; a route that more than 87,000 motorists use on a daily basis.

In February, the Nevada Department of Transportation began closing stretches of U.S. 50 between State Route 341 and Chaves Road in Dayton, NV, to install high livestock fencing on both sides of the highway largely along rural roadway stretches to reduce vehicle-horse collisions.

The Nevada DOT is also placing roadway lighting on the highway at the end of each fenced section for enhanced visibility for motorists.

In addition, in April, the Oregon Department of Transportation recently received a special one-time allocation of $7 million in general funds from the Oregon legislature to invest in wildlife corridor projects statewide. The Oregon DOT said it has had “great success” with wildlife undercrossing structures in recent years, with five crossings built to date in the state, all on U.S. 97, leading to an 86 percent reduction in wildlife-vehicle collisions.

PennDOT Wins Governor’s Award for State Litter Action Plan

Governor Tom Wolf (D) recently presented a group of employees from the Pennsylvania Department of Transportation and the Pennsylvania Department of Environmental Protection (DEP) with Governor’s Awards for Excellence in recognition of their efforts to develop the first-ever Pennsylvania Litter Action Plan, unveiled in December 2021.

The Governor’s Awards for Excellence recognize exemplary job performance or service that reflects initiative, leadership, innovation, and increased efficiency. The PennDOT and DEP team was among 50 employees from 12 state agencies honored by Governor Wolf for exceptional accomplishments in 2021.

Through coordination with over 100 stakeholders, the employees from both state agencies spearheaded the development of a plan with the goal to shift the focus of Pennsylvania’s response to litter from cleanup to prevention. The plan includes resources and suggestions for the General Assembly, state agencies, local governments, and the public.

The honorees are Natasha Fackler, former policy director for PennDOT; Emily Watts, former executive policy specialist at PennDOT; Jessica Shirley, former DEP policy director; and Kate Cole, DEP’s current policy director.

“It’s clear that in order to truly see less litter in Pennsylvania, we need to focus on getting people not to litter in the first place,” said PennDOT Secretary Yassmin Gramian, in a statement. “The Litter Action Plan provides real solutions that can be implemented at the state, local, and individual level to help make a cleaner Pennsylvania for all of us. I’m so proud of the work that this team has done to develop this plan.”

“This award is very well deserved and represents the work that this team has done to keep the Keystone State litter free,” added DEP Secretary Patrick McDonnell. “This plan is needed because of the growing – and frankly disgusting – problem of litter polluting our lands and waters. The Litter Action Plan sets us on a path to a cleaner, more beautiful Pennsylvania.”

PennDOT said it spends roughly $14 million each year on litter cleanup statewide, while DEP has funded “Pick Up Pennsylvania” community litter cleanups and illegal dumpsite cleanups for over two decades – supporting volunteers in removing many tons of trash from the land and waters. 

The persistence of littering prompted PennDOT and DEP to collaborate with Keep Pennsylvania Beautiful to conduct the first comprehensive state study to inform development of the Litter Action Plan, with a focus on changing littering behavior. “It is my privilege to congratulate the Pennsylvania Department of Environmental Protection and Pennsylvania Department of Transportation for their vital and mission-based work to develop the state’s first-ever Litter Action Plan,” noted Shannon Reiter, president of Keep Pennsylvania Beautiful. “The plan’s blueprint for implementing preventive measures and behavior changing strategies to reduce littering in Pennsylvania will benefit and positively impact the health, safety, and beauty of whole communities all across the Commonwealth.”

Oregon DOT Commits $100M to EV Charging Infrastructure

The Oregon Department of Transportation is committing $100 million over the next five years to build out Oregon’s public electric vehicle charging network on several major road corridors, as well as in local communities statewide.

[Above photo by the Oregon DOT]

The Oregon Transportation Commission approved that funding amount – which comes from a mix of federal and state sources – at its March 30 meeting.

The Oregon DOT said about two-thirds of the funding — $52 million from the 2021 Infrastructure Investment and Jobs Act plus a required 20 percent match — must be spent on EV charging infrastructure along “Alternative Fuel Corridors,” as per guidance from the Federal Highway Administration.

Alternative Fuel Corridors are roads approved by the FHWA on which states may use federal funding to build alternative fuel infrastructure. Electricity is an alternative fuel, and Oregon has seven corridors approved for federally funded EV charging: Interstates 5, 84, 82, and U.S. 26, 101, 20, and 97.

The remaining third of the money — $36 million — will be used to close EV infrastructure gaps beyond those seven corridors. More charging sites in rural and urban areas, underserved communities, and apartment complexes will allow more Oregonians to charge where they live, work, and play, noted Amanda Pietz, administrator for Oregon DOT’s policy, data & analysis division, in a statement.

“We know that range anxiety is a big factor in people’s reluctance to make the switch to electric vehicles, especially in more rural parts of the state,” said Pietz. “This investment will build Oregonians’ confidence that an EV can fit into their lives and get them where they need to go.”

She noted this $100 million investment focuses on building out charging infrastructure for light-duty EVs like cars, sport utility vehicles, and trucks because “demand is high and the technology is mature.”

Electrifying Oregon’s transportation system is a “key outcome” outlined in Oregon DOT’s Strategic Action Plan, and part of the state’s push to reduce greenhouse gas emissions from transportation and address the climate change crisis.

“Money doesn’t surmount all barriers,” said Pietz. “Regulations and policies that benefit electrification play a role, too, and we rely on our partner agencies for help there. Couple that with our other work and investments in walking and rolling, bicycling, and congestion pricing, and we can move the needle on transportation emissions in a big way.”

Louisiana DOTD Wins Award for Brine Management

Scott Boyle (seen above), assistant administrator of operations for District 2 of the Louisiana Department of Transportation and Development, recently received an award on behalf of his district’s handling of brine disposal.

[Above photo by the Louisiana DOTD. Jefferson Parish President Cynthia Lee Sheng (at left) presents a ‘Certificate of Merit’ to Louisiana DOTD’s Scott Boyle.]

Louisiana DOTD’s District 2 received the 2022 Environmental Leadership Award from the Jefferson Parish Department of Environmental Affairs for its efforts to dispose of excess brine used in winter road clearing operations to minimize the impact on the local water table.

In January, in preparation for an anticipated ice storm in the greater New Orleans area, Louisiana DOTD produced nearly 1,800 gallons of brine to combat ice on the region’s most critical roads and bridges. However, once the weather event was over, a surplus of brine remained.

“In the past, we have tried to store the brine in stationary tanks, but algae growth and the degradation of the solution from heat and sunlight prevented us from re-using the brine for future winter events,” said Boyle in a statement. “Knowing that this material needed to be disposed of responsibly, we contacted the Jefferson Parish Storm Water Management team for guidance.”

Louisiana DOTD then worked with the Jefferson Parish Bridge City Wastewater Treatment Plant – located next to District 2’s headquarters – to dispose of the brine. The mixture was disposed of on a drying bed located on the treatment plant property, filtering out a portion of the salt before introducing the salted water into the plant slowly so it would not shock or upset the wastewater treatment process.

According to Jefferson Parish, these awards recognize those individuals, businesses, or organizations that strive for environmental leadership through programs and actions that improve stormwater quality and/or quantity, thereby reducing the amount of pollution that enters Jefferson Parish waterways.
“It is an honor and a privilege to be recognized for our partnership with Jefferson Parish as [Louisiana] DOTD ensures that we are doing our part to improve our surrounding waterway quality,” Boyle said. “Actions can have significant impacts on the region that we love to live and play in.”

Announcing Center for Environmental Excellence Resilience Webinars

The Center for Environmental Excellence in partnership with the Federal Highway Administration invites you to join in parts two and three of a three-part webinar series on Resilience. The webinars will include speakers from various state DOTs as well as FHWA and AASHTO. Find further description and registration, as well as recording and meeting materials from the first session below:


Reducing the effects of climate change on transportation infrastructure using natural and nature-based solutions (5/9/22)

Recording and meeting materials: https://environment.transportation.org/past-event/resilience-webinar-series-reducing-the-effects-of-climate-change-on-transportation-infrastructure-using-natural-and-nature-based-solutions/


Integration of climate change projections in hydrologic and hydraulic design in transportation projects (5/31/22)

Registration: https://us02web.zoom.us/webinar/register/WN_Fv4Y68VwTHa9MBe1-lI-gQ

Future climate conditions, including increased precipitation and sea-level rise, are anticipated to impact the structural performance, and therefore, the functionality of our transportation facilities. As such, the integration of climate considerations into the design of transportation facilities is an important step in ensuring that target levels of facility performance are met as climate conditions change. This integration, however, is not yet a standard practice included in hydrologic and hydraulic design. Engineers can benefit from being provided with methods and tools that facilitate the integration of climate considerations, especially of scientific advances that have proven to be effective in engineering decision-making. This webinar will feature selected methods and tools used by transportation agencies in the United States and overseas to account for climate data in the hydrologic and hydraulic design of transportation facilities.


Integrating Natural Hazard Resilience into the Transportation Planning Process (7/6/22) also from 1-2:30 EST

Registration: https://us02web.zoom.us/webinar/register/WN_lpclw6-jTOqLHhRhSLBB6w

Climate change and other natural hazards may threaten lives, property, and other assets. Often, natural hazards can be predicted. They tend to occur repeatedly in the same geographical locations because they are related to the weather patterns and physical characteristics of an area. At whatever stage a planning agency is in its planning cycle, there are resilience-related actions that can be taken in order to begin appropriately integrating natural hazard considerations into the transportation planning process. Currently, there has been a resurgence of interest in resilience-based planning activities due to the frequency of natural disasters, the global movement to fight climate change, and even due to the emphasis on planning for resilience in the recent federal Bipartisan Infrastructure Law. This webinar will provide an overview and integrate key examples showing how transportation planning agencies can most appropriately and effectively integrate resilience into the transportation planning process.

Colorado Moving Forward with Clean Truck Strategy

The administration of Colorado Governor Jared Polis (D) recently finalized its Clean Truck Strategy – initially unveiled in March – after what the governor described as “extensive public input.”

[Above photo by the Colorado DOT]

Developed by the Colorado Energy Office, the Colorado Department of Transportation, and the Colorado Department of Public Health & Environment, the 27-page Clean Truck Strategy seeks to encourage the adoption of zero-emission medium- and heavy-duty trucks statewide, potentially reducing greenhouse gas or GHG emissions from those vehicles by at least 45 percent in Colorado by 2050.

Medium- and heavy-duty vehicles covered by Colorado’s Clean Truck Strategy include tractor-trailers, school buses, snowplows, delivery vans, large pick-up trucks, and many different vehicle types in between.

A separate 147-page study compiled by the Colorado Energy Office found that medium- and heavy-duty vehicles are the second-largest source of GHG emissions in the transportation sector, producing 22 percent of on-road GHG emissions despite making up less than 10 percent of the total Colorado vehicle population.

That study found if Colorado pursues an “accelerated transition” to zero-emission medium- and heavy-duty vehicle models, it could cut GHG emissions by 45 percent to 59 percent, reduce nitrogen oxide emissions by 54 percent to 93 percent, and reduce particulate matter emissions by 53 percent to 68 percent below 2005 levels by 2050.

Those three state agencies said they would continue collaborating with stakeholders and initiating implementation on “near-term” actions over the next few months, including:

Those agencies also expect to update the Clean Truck Strategy every two years to respond to “evolving market and lessons” learned from implementing the plan’s near-term requirements. “Colorado has enormous opportunities to reduce pollution and improve quality of life by transitioning from diesel to zero-emission trucks and buses,” explained Will Toor, executive director of the Colorado Energy Office, in a statement. “This strategic plan creates a framework for achieving big things through investment, collaboration, and regulation.”

Caltrans Highlights Key Stormwater Pollutants

As part of its “Let’s Change This to That” public education campaign, the California Department of Transportation is highlighting the top six sources of stormwater pollution across the state as well as ways to prevent them from contaminating California’s waterways.

[Above photo by Caltrans]

The agency manages stormwater runoff and mitigates potential pollution within its 350,000 acres of right of way, which includes more than 15,000 centerline miles of highways. This effort involves picking up roadside litter and clearing out storm drains to preserve roadway safety and drivability during all types of weather conditions.

Unlike water that goes down the sink or toilet in a home, Caltrans said stormwater is untreated and flows directly into lakes, rivers, and other waterways.

The agency noted that as stormwater travels into storm drains, it captures pollutants from highways, streets, sidewalks, and yards that flow into waterways. The top six pollutants have an outsized impact on the water quality of lakes, rivers, streams, and the ocean, and many are preventable through small actions Californians can take:

  • Trash and litter: Properly secure items in truck beds and put trash and recycling in the correct bin.
  • Sediments: Prevent soil erosion by using mulch in the garden, planting trees and shrubs, and sweeping driveways instead of hosing them off.
  • Nutrients: Avoid over-fertilizing lawns and plants and limit vegetation waste by keeping fallen leaves out of storm drains.
  • Bacteria: Limit pet and Recreational Vehicle or RV waste by picking up after your pet and using appropriate RV dumping stations.
  • Metals: Regularly check tire pressure, change oil and fluids, and use commercial car washes to prevent metals generated from vehicle, tire, and brake wear from ending up on highways.
  • Pesticides: Use organic pesticides and properly dispose of unused portions.

“Preventing stormwater pollution requires the help and support of every Californian, and it starts with keeping highways and roadways clean,” noted Steven Keck, acting director at Caltrans, in a statement.

“Californians must work together to take necessary steps to prevent pollution at the source and keep our waterways clean,” he said.

With the intensify drought conditions predicted to increase statewide this year, Caltrans noted it is amplifying water quality as a top priority.

During a drought, the state’s lakes, rivers, and streams have lower water levels, which leads to a higher concentration of pollutants. By preventing a buildup of metals, trash, and other pollutants on highways and roadways in dry conditions, Californians can help keep pollutants from traveling into local waterways during rainstorms.
