Drivers on this Tacoma highway will be shifting for a few months as state builds overpass
Construction of the new tolled highway from the Port of Tacoma to Interstate 5 is going to impact drivers on state Route 509 for several months beginning Thursday, the state Department of Transportation said.
An overpass under construction near Alexander Avenue is going to require northbound SR 509 traffic to shift to the west.
At 8 p.m. Wednesday, one lane of northbound SR 509 will close so that northbound lanes can be re-routed under the first portion of the new overpass, WSDOT said.
The new overpass will eventually connect southbound SR 167 — part of the state Route 167 Completion Project — to southbound SR 509.
Drivers can expect to remain in the new lanes through late fall 2025, WSDOT said.
The $376 million SR 509 to I-5 portion of the SR 167 Completion Project is scheduled to open in 2026. The third stage will continue the project to Puyallup but is not yet under construction. The entire project is scheduled for completion by 2030.
