The state Department of Transportation has lifted a weight limit on the state Route 167 Puyallup River bridge and replaced it with a lane restriction.
A weight limit of 10,000 pounds gross vehicle weight was to go in effect Feb. 15. The agency has opted to restrict commercial trucks with that weight to the right northbound line while crossing the aging bridge.
The new restriction will go into effect Feb. 22.
About 15,000 vehicles – including 2,400 commercial trucks – travel the bridge every day, according to the Transportation Department.
Never miss a local story.
A recent inspection of the 86-year-old structure showed deterioration in the floor beams. Restricting heavier vehicles to a single lane is expected to reduce deterioration.
A replacement bridge, which will cost an estimated $53.7 million, is scheduled for design in 2014.
