SR 167 Completion Project - 70th Avenue East Bridge construction

November Update

With all ten of our giant girders in place over I-5, bridge construction is moving forward with preparation for deck paving. The contractor is starting to install giant foam blocks on the northbound side of the new 70th Avenue East Bridge. These blocks, which look like Styrofoam, are lightweight but very strong and will eventually support the roadway on both sides of the bridge.

SR 99 Roundabout

Construction on the new SR 99 roundabout continues to progress. In the coming weeks,  northbound SR 99 traffic will move to the new roundabout, which will allow  crews to start work on the roundabout’s southbound lanes. Drivers who use SR 99 in this area should expect intermittent lane closures as we prepare for this transition. Traffic on southbound SR 99 will stay in its current alignment until the roundabout is complete.

Other project work scheduled for November includes pouring concrete sidewalks near the SR 99 roundabout and erosion control measures for the new Interurban Trail parking lot.

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.
