Ted Alvarez reports on a new overpass over Interstate 90 in Washington State that will offer safe passage over the freeway for wildlife.

The overpass is being built just east of Hyak and Snoqualmie Pass to connect the north and south Cascades. Three riparian underpasses are under construction nearby to offer safe passage to salmon.Together, the $6.2 million project is creating a wildlife superhighway.

According to Alvarez, the wildlife overpass is part of a larger $900 million project to add two dozen more crossings in a 15-mile section of I-90 as it crosses Snoqualmie Pass.

The article includes a lot more detail about the advocacy and planning that went into the project.
