SNOQUALMIE, Wash. – The Washington State Department of Transportation began construction on the first-ever wildlife crossing over Interstate 90 on Wednesday.
The bridge is in the Snoqualmie Pass area.
WSDOT is currently building one of the arches that will act as a support for the crossing.
After the arch is complete, workers will create a path on the top of it for animals to walk over the freeway.
The bridge is part of a project that aims to bring 20 underpasses and overpasses to the interstate.
The project is expected to be completed by the end of 2018.
