BOTHELL — Weekend I-405 travelers will need to find another route this weekend.

Starting at 10 p.m. Friday, southbound I-405 will be closed between the Highway 522 interchange and the Highway 527 interchange for paving work. The interstate is expected to reopen at 4 a.m. Monday.

The work is part of the I-405/Brickyard to Highway 527 Improvement Project covering about 4½ miles near the border of Snohomish and King counties. It’s expected to be completed by 2028.

The $834 million project will add a second toll lane on I-405 and improve access to Sound Transit’s Stride bus rapid transit system.

“This project includes three new Stride stations and will build direct access ramps to the (Express Toll Lane) system at SR 522, along with a partial direct access interchange at SR 527 to and from the south connecting to the Canyon Park Park & Ride,” a state Department of Transportation project page states. “These enhancements will allow Stride vehicles to travel in the new ETLs between Lynnwood and Bellevue while stopping briefly to pick-up and drop-off passengers without having to leave the highway system.”

The project will also “address aging infrastructure” and fix multiple fish barriers, according to the transportation department. It will also add sound walls and includes stormwater work.
