Traffic Advisory: Bridge maintenance to close SE Portland’s Deardorff Road Bridge Dec. 21-Dec. 31

(Dec. 18, 2015) – The Portland Bureau of Transportation advises the traveling public that preventive maintenance will require closure of the Deardorff Road Bridge between SE Foster Road and SE Flavel Street, from 7 a.m. Monday, Dec. 21 through Thursday, Dec. 31. The bridge will need to be closed 24-hours a day until the work is completed. A detour route will be in place during the closure.

Also known as the Cedar Crossing Bridge, the structure is the only covered bridge in Multnomah County.

For preventive maintenance that will extend the life of the bridge, the deteriorated asphalt on the bridge deck surface will be removed. PBOT crews will install a waterproof membrane to prevent water from penetrating into the structure. Additional repair time may be needed if bridge deck timbers need to be replaced. The bridge deck surface will be resurfaced with asphalt.

Work has been scheduled for this time to coincide area school closures for the holiday season. The bridge is a key route for several school bus routes in the area.

Detours will be set up to help travelers through the area during the scheduled bridge closure.

Traffic traveling southbound on SE 134th/SE Deardorff Rd will be detoured west on Foster Road, then southbound on SE 110th Drive/SE 112th Avenue, to eastbound SE Flavel Street, to SE Deardorff Road. Traffic traveling northbound on SE Deardorff Road will be detoured west onto SE Flavel Street to northbound SE 112th /SE 110th, then to eastbound SE Foster Road.

Local access will be provided to residences on SE 134th between SE Foster Road and SE Deardorff Road.

The public is advised to expect delays, travel cautiously, observe closure signs, use the detour and alternate routes if possible. Advisory message boards were placed in the area earlier this week and will remain during the duration of the project.
