Large concrete barriers are in place as of Jan.28th after Thurston County officials closed Bridge No. L4 on Littlerock Road Southwest between 110th Avenue Southwest and 93rd Avenue Southwest to structural deficiencies, according to news release. The bridge reopened Wednesday, Feb. 19 to traffic, with some restrictions in place until the bridge is repaired later this year.

A small bridge on Littlerock Road south of Tumwater reopened Wednesday with some restrictions — and those will remain in effect until after the bridge is replaced later this year, officials say.

The two-lane bridge over Salmon Creek, between 110th Avenue Southwest and 93rd Avenue Southwest, has reopened for passenger vehicles and pickups without trailers, according to a news release from the county. In addition, the speed limit over the bridge has been dropped to 25 mph from 50 mph, and heavier trucks and buses will continue be required to use a nearly 4-mile detour.

“That will remain in place until the bridge is replaced, later this fall,” said Matt Unzelman, a civil engineer with the county.

The bridge, which was built in the 1950s, was closed Jan. 27 after crews found scour under the center pier, according to road operations manager Lucy Mills. Scour occurs when water washes away rock or footing around a bridge’s foundation, she said.

The structural problems prompted county officials to apply for a grant through the Washington Department of Transportation to pay for repairing or replacing the bridge, Unzelman said.

“We got $3.4 million in federal funding to replace the bridge,” he added.
