Crews will close two lanes across the westbound Tacoma Narrows Bridge for several hours next week.
The two remaining westbound lanes of state Route 16 will stay open through each night.
The partial closures will be from 7 p.m.-6 a.m. Tuesday, Wednesday and Thursday.
During the lane closures, crews working for the state Department of Transportation will continue work to remove original steel rivets from the 1950 bridge’s westernmost expansion joint in preparation for replacing it.
They will use pneumatic rivet busters to shear off the heads of the rivets, punch the rivet stems out of the steel joints, and replace the rivets with bolts.
Transportation Department spokeswoman Claudia Bingham-Baker warned that work will be noisy and asked nearby residents for their tolerance during this work.
Replacing the westernmost expansion joint will occur over an extended weekend, the date to be announced when plans are finalized, Bingham-Baker said. Doing preparatory work before the extended weekend will allow the contractor to work more efficiently within that limited time frame, she said.
