Traffic shift coming to I-405 near SR 167 interchange this week

Drivers who use northbound Interstate 405 near SR 167 in Renton should prepare for a new traffic configuration in this area as soon as this Wednesday morning, April 4.

Overnight Tuesday, April 3, construction crews working for the Washington State Department of Transportation plan to complete striping work to move the northbound I-405 lanes farther to the right side of the roadway. The same number of lanes will remain in place after the shift is complete.

This traffic change is necessary to provide crews enough space to create a new construction work zone in between the southbound and northbound lanes of I-405. They will use this area to continue building the future flyover ramp for the I-405/SR 167 Interchange Direct Connector Project.

This work requires lane and ramp closures on southbound I-405 near the SR 167 interchange. The construction activities are weather dependent and subject to change. If crews cannot complete the work this weekend, they will postpone their work to the next dry nights.
