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.
What to expect
You can get information about our three active projects here:
I-5 NB Seneca to SR 520 - Mobility Improvements
I-5 NB Lowell Rd to Snohomish River - Concrete and Expansion Joint Rehab
I-5/NB Marine View Dr to SR 529 - Corridor & Interchange Improvements
In general during construction of the various projects, people can expect nighttime lane, ramp and directional closures, as well as weekend-long construction that may include lane reductions, directional closures and full-time lane closures that last several days.
See the "related links" tab for future projects.
Our draft 10-year plan for I-5 in the Seattle area includes more than two dozen projects.
