SALT LAKE CITY (AP) — Transportation officials are building a wildlife bridge over a part of Interstate 80 where more than 100 animals have been killed over the last two years. Mule deer, moose, elk and a cougar are among the animals found dead on the highway between Salt Lake and Park City. The $5 million project will be finished in the fall.

The Utah Department of Transportation the project will close part of eastbound I-80 overnight in Parley’s Canyon Wednesday. Eastbound Interstate 80 will re-open Thursday. The closure affects the area between the Jeremy Ranch and Lambs Canyon exits. Drivers will have to use alternate routes, though it could add up to 90 minutes to their trips.

In coordination with this project, another crew will repave both directions of I-80 from Lambs Canyon to west of Kimball Junction in summer 2018.

The Utah Department of Transportation (UDOT) will add a truck lane on westbound I-80 from Jeremy Ranch to Parleys Summit, complete wildlife fencing in both directions within the project limits and build a wildlife crossing near Parleys Summit. UDOT will also augment the fencing and new wildlife overpass by installing cattle guard at the Parleys Summit interchange. Additionally, crews will build a noise barrier near Jeremy Ranch to mitigate freeway noise for nearby residents.

In order to construct the new truck lane and noise wall, wildlife fencing near Jeremy Ranch has been temporarily removed and is being reused in other areas within the project limits. Temporary construction fencing has been installed in its place in an effort to keep wildlife off the roadway as much as possible during construction. The new noise wall is scheduled to be complete in late summer 2018.
