The Lacamas Creek Bridge, located along 288th Street South just east of 48th Avenue South, will close July 13 while it is replaced. The bridge is expected to open in mid-October.
A 7.5 mile detour will take motorists along 40th Avenue South, Tisch Road South, and 72nd Avenue South. A detour route is available here.
The two-lane bridge, which is located east of Roy, will be replaced with a pre-cast concrete slab bridge with paved shoulders. The approaches to the bridge will also be reconstructed.
The existing bridge was built in 1954 and carries approximately 1,675 vehicles a day.
“The existing bridge was not designed to accommodate modern vehicle loads and volumes,” said Kraig Shaner, P.E., Pierce County Public Works bridge engineering supervisor. “Maintenance needs have been increasing as the bridge ages. The replacement will remove all current deficiencies and make the passage over Lacamas Creek more dependable for the traveling public.”
The existing bridge deck is made of creosote-treated timber beams covered by concrete planks. It is supported by concrete abutments and footings.
The contractor for the project is Zemek Construction. The construction cost is approximately $840,600. The project will be funded with $672,480 in Federal Highway Bridge Program (HBP) Replacement Funds and $168,120 in County Road Funds.
