New westbound SR 16 bridge opening near Purdy mid-August

Fish project reaches halfway point; eastbound SR 16 traffic shift up next

GIG HARBOR – An important milestone for fish in Purdy Creek and travelers on State Route 16 is coming mid-August, including a traffic shift.

Crews have finished building the first of two new 206-foot-long bridges that replace old culverts under the highway. With this work complete, SR 16 westbound lanes from Gig Harbor to Port Orchard can be shifted off the center of the highway and onto the new bridge. Construction crews will make that shift during the week of Aug. 14.

Up next: Eastbound SR 16

Once the westbound bridge is open to traffic, crews will prepare for shifting the eastbound travel lanes. Work will begin to reconfigure the temporary median lanes.

Creating the new alignment will take a few weeks to complete. When grading and repaving are finished, crews will shift eastbound SR 16 to the center of the highway. This will make room for construction of the new eastbound bridge. The new, temporary configuration will have the eastbound SR 16 travel lanes about 10 feet below the westbound bridge.

A temporary regulatory speed limit reduction also will be in place on eastbound SR 16 through the work zone, dropping from 60 mph to 45 mph between mileposts 17.15 and 18. The speed limit is enforceable as soon as the signs are uncovered. The reduced speed limit and traffic shift will remain in place until the project is complete by the end of 2024.

The Washington State Department of Transportation will announce the date for the eastbound traffic shift in advance on the Purdy Creek project webpage, the WSDOT app and real-time travel map.

Update on work at SR 302 Spur

The SR 302 Spur remains closed between Purdy Lane Northwest and 144th Street Northwest. Earlier this month, crews finished installing the piers for the bridge that will replace the culvert under the road. Work to rebuild the streambed is underway. The contractor expects to complete the new bridge and reopen the road by the end of 2023.

Improving fish passage

The construction is part of WSDOT’s program to remove barriers to fish under state highways to help them better travel through waterways during migration. Purdy Creek under SR 16 and the SR 302 Spur currently has undersized culverts that are barriers to fish migration. Purdy Creek is home to native fish species including Chinook salmon and chum salmon. Coho salmon, sculpin and coastal cutthroat and steelhead trout are also found in the stream.

WSDOT urges drivers to slow down and pay attention in work zones to keep all roadway users safe.

Slow down on ice and snow.

It's easier to skid or lose control traveling at higher speeds. Give yourself more time to stop.

Carry chains, practice installing them.

Winter conditions could mean chains are required on your route. Practice putting them on your vehicle ahead of time.

Pack your winter car kit.

Carry extra supplies like warm clothing, ice scraper and brush, jumper cables and other emergency items.
