SR 167 Completion Project - 70th Avenue East Bridge construction

May 2021 Update

Southbound SR 99 shifts into the roundabout May 15

On Saturday morning, May 15, the southbound lanes of SR 99 will move into the new SR 99 roundabout. The biggest impact to travelers will start Friday, May 14 at 10 p.m. when SR 99 is reduced to one lane. Flaggers will direct traffic through the work zone, but overnight travelers should expect delays.  

When the shift is complete, both directions of SR 99 traffic will be using the roundabout, however, construction in the area continues. The roundabout will fully open to traffic this summer, when the new 70th Avenue East replacement bridge opens to traffic.

As a reminder, drivers should slow down when approaching the roundabout and avoid driving next to or passing large trucks, as trucks may straddle lanes to safely pass through.

This graphic shows the flow of traffic after southbound SR 99 lanes shift into the roundabout. Construction continues and the roundabout fully opens with the new bridge this summer.

Bridge construction

Construction continues on the new four-lane bridge that will replace the two-lane 70th Avenue East Bridge. Current work includes paving the approaches to the bridge and installing the concrete barriers on each side of the bridge.

In August 2020, crews lifted ten supersized beams across I-5 to create the bridge. In January 2021, the bridge deck was paved in one day. Watch this video to see how.

About the SR 167/70th Avenue East Bridge project

The SR 167 / 70th Avenue Bridge project is part of a larger effort to complete SR 167 and improve connections to I-5 and the Port of Tacoma. The new four-lane bridge replaces a two-lane bridge and provides a 12-foot wide path for pedestrians and bicycles. WSDOT will remove the existing 70th Avenue East bridge as part of the next stage of construction. The project also includes a new roundabout at the 70th Avenue East/SR 99 intersection, a new Interurban Trail parking lot and several hundred feet of new trail.
