Revive I-5: Preserving a vital freeway

Project overview

Dozens of preservation projects are planned to revive Interstate 5 in King and Snohomish counties. Washington’s main freeway was built in the 1960s and needs major preservation and renovation work. Over the coming years, Revive I-5 projects will include pavement repair and full replacement, expansion joints, and seismic work to strengthen bridges against earthquakes. While many projects are included in the draft plan; others are not funded at this time. Maps below show the various projects.
