A crane places a pre-formed concrete arch section on the footings.

Wing walls add structural support and also channel animals into the arch crossing.

According to an I-70 Wildlife Crossing summary of the project produced by Contech, “The CON/SPAN used on our I-70 Wildlife Crossing was great for this application,” said Lyndon Friant, UDOT Resident Engineer.  “It was installed quickly and effectively, allowing for minimal impact to the traveling public…”
