The U.S. 60 Pinto Creek Bridge is also home to the endangered hedgehog cactus, which grows only within a several-mile radius of the site. About a foot high, usually covered in spines and often with red flowers at the top, the species is listed as endangered by the U.S. Fish and Wildlife Service and is protected under Arizona law.

When the bridge replacement project began in 2018, a team comprised of biologists from the Arizona DOT and from the Desert Botanical Garden in Phoenix safely removed 34 cacti potentially affected by the construction work, then nurtured and propagated, replanting 61 total cacti in early March. This relocation effort is the latest step in a long-term partnership between the Arizona DOT and the Desert Botanical Garden to protect hedgehog cactuses that only grow in one tiny area of the state.

“ADOT has a responsibility to respect the environment and to make sure the plants and animals that make Arizona special are protected,” said Josh Fife, Arizona DOT’s biology team lead, in a statement. “We’re proud that the work we did will make sure the Arizona hedgehog cactus will continue to exist in the one special place in the world where they thrive.”

This cacti protection effort took on added importance in the summer of 2021, when wildfires swept through the project site, threatening some of the cacti in that area that were not removed because they were not threatened by construction.

“The plants on site could have easily been destroyed in the fire which is why it was a good thing these plants were taken back to Desert Botanical Garden out of harm’s way,” noted Steve Blackwell, conservation collections manager for Desert Botanical Garden.

“That was an important side benefit of taking cactus out when we did. Another valuable part of this process was that we were able to hand pollinate the plants at the Garden, clone the mother plants and develop a seed bank for future preservation,” he added. “This is a great win for the environment”

Minnesota DOT Works to ‘Rejuvenate’ Live Snow Fences

The Minnesota Department of Transportation plans to “rejuvenate” seven so-called “living snow fences” in southwest Minnesota as part of a month-long effort to ensure the 20-year-old plantings can survive for another two decades.

The agency noted that a “living snow fence” is comprised of trees, shrubs, native grasses, and/or wildflowers to trap snow as it blows across fields, piling it up before it reaches a bridge or roadway.

“Rejuvenation” work includes pruning healthy trees while removing and replacing any dead trees and shrubs. The agency noted it schedules such work on living snow fences between March and April specifically to reduce interference with the state’s bat and bird populations.

“A living snow fence is more than landscaping and highway beautification, it serves a purpose,” explained Dan Gullickson, Minnesota DOT’s blowing snow control shared services program supervisor, in a statement.

“We use nature to control blowing snow and rejuvenating these living snow fence sites will safeguard the health and vitality of the plantings,” he added.

The Minnesota DOT said living snow fences offer multiple infrastructure benefits, including:

  • Prevent the formation of large snowdrifts and icing on roads.
  • Improve motorist visibility by reducing whiteout conditions due to blowing snow.
  • Control soil erosion and reduce spring flooding.
  • Lessen environmental impact by reducing the need to use salt on the roads during winter.

Alaska Budget Contains Ice Road Maintenance Funds

The fiscal year 2023 state budget proposed by Governor Michael Dunleavy (R) contains maintenance funding for the Dick Nash Memorial ice road that will help tribal transportation departments maintain the frozen Kuskokwim for travel in the 2022/2023 winter season.

By contrast, in 2021, contributions from community stakeholders covered half of the ice road’s maintenance costs. However, as heating oil delivery and diesel costs are now over $6 per gallon in the region – and the state is experiencing a funding surplus based in part on high oil prices – Governor Dunleavy said in a statement that he believes it is “only right” to provide community relief where possible.

That is why, in addition to the proposed funding in his FY 2023 budget, the Alaska Department of Transportation and Public Facilities plans to recover any remaining maintenance costs via federal surface transportation funding during the 2022/2023 winter season, Gov. Dunleavy said.

The Kuskokwim ice road – which can stretch up to 300 miles long – serves 17 villages and helps Alaskan rural communities move goods and services during winter months. They are a safe alternative when poor weather prevents airplanes from flying, according to the Alaska Department of Transportation and Public Facilities, and proved an efficient way to distribute COVID-19 vaccines.

Maintaining ice roads goes beyond plowing snow and placing reflectors. For example, the ice road crew serving the Village of Napaimute has developed a cell phone application to measure ice thickness. That application integrates ice-penetrating radar with traditional Native knowledge and local observations into an easy-to-access cell phone data format.

“I had the opportunity to travel the Kuskokwim Ice Road for the first time on a recent visit to the Villages of Napakiak and Napaskiak,” the governor said. “All those hundreds of miles of drivable ice are truly an Alaskan feat … and I heard from many residents about the importance of the road during the winter months for health, safety, commerce, and recreation. I’m glad we have identified funding to cover this expense from existing authorities.”

Nevada DOT Launches Latino Cultural Preservation Project

The Nevada Department of Transportation and contractor Mead & Hunt are working to develop a “multiple property documentation form” or MPDF to help preserve Latino-related properties statewide, with a primary focus on the cities of Las Vegas and Reno.

“This is an exciting new project that will pave the way for similar DOT projects throughout the country to preserve the rich cultural fabric of our communities across Nevada,” explained Cliff Creger, Nevada DOT’s chief of cultural resources, in a statement. “We are seeking input from the public on the important people and places to northern and southern Nevada’s Latino communities.”

He added that the resulting MPDF from that outreach seeks to reflect the way the Latino community defines the importance and use of properties. It also would cover how such properties are directly associated with Latino “themes” as well as their chronological periods in the historic contexts and/or which physical features convey distinctive design features.

The goal of the project is to build relationships within the Latino community, integrate the outreach findings and program into the MPDF, then develop a historical context for future transportation projects in Nevada.

This project also aims to “understand, explore, and propose criteria” to improve the “evaluation eligibility” of historical properties based on the Latino community’s unique past, standards, and values, the agency added. 

“We understand that the architectural history representation of the Latino culture is unique to its own past and can be understood from its own standards and values,” Creger noted.

This particular cultural outreach project undertaken by Nevada DOT is reflective of similar efforts by state departments of transportation nationwide.

For example, the Colorado Department of Transportation debuted a documentary called “Durango 550 – Path of the Ancestral Puebloans” in January to show how the agency worked with archaeologists and regional Native American tribes to document, study, and ultimately share the discoveries unearthed near Durango in southwest Colorado.

That particular archaeological excavation took place in 2018 and 2019 ahead of construction on the US 550-US 160 Connection South project in 2020.

“This documentary shows the unique collaboration of all entities involved, laying the groundwork for a new approach to archaeology, blending western science with traditional cultural beliefs,” explained Greg Wolff, a Colorado DOT archaeologist, in a statement.

In July 2021, the Ohio Department of Transportation helped open the new 54-mile-long Quaker Heritage Scenic Byway that seeks to foster a “new awareness” of cultural and historical diversity in rural southwest Ohio with stops along the way telling the story of Quakers who migrated to the region from the late 18th to the late 20th centuries.

That project helped reveal numerous layers of local history such as Quaker interactions with Native American communities, agriculture and land use, abolitionism, and religious practices – all identified through historical research, digital mapping, and told through “interactive” narratives.

Finally, the latest episode of the Environmental Technical Assistance Program or ETAP Podcast discussed ways state DOT cultural resources programs are exploring to identify and preserve homes built in the 30 years following World War II that may have potential historical significance.
