Project Description

We are planning emergency repairs to the north approach to the Stark Street Bridge. The bridge closed September 17 when the northwest retaining wall on the  approach collapsed. The northeast retaining wall across from it is also at risk of collapse.

The Stark Street Bridge and roadway were built in 1914. Over the last decade, multiple crashes by cars and trucks have damaged the retaining walls on the north approach.

The approach to the bridge from the Historic Columbia River Highway needs to be rebuilt. It will not be safe for car and truck traffic until then. This could take up to six months.

We have been consulting with the Oregon Department of Transportation, who maintains the highway. We have also been talking to engineers, biologists, historical resource experts and our contractor. We are now working as well with utilities who will be affected by the roadway construction.

With the bridge closed, we also found a 6 to 8 inch hole in the bridge deck. This has now been repaired.

Traffic Impacts

The bridge will remain closed to cars and trucks until repairs are complete. Drivers should detour to the Sandy River Bridge in Troutdale. 

The sidewalk on the bridge will remain open to bicycles and pedestrians until construction, and then a detour will be posted.

Please drive safely. Survey crews or other workers may be on the shoulder or the side of the road at various times. Please be careful and drive slowly when workers are present.
