Construction to start on Graham Creek culvert with eastbound traffic detour for up to 10 weeks

We’re replacing failing culverts on U.S. 30 with a concrete culvert that’ll be easier for native migratory fish, like salmon and steelhead, to pass through. We’re also repairing the pavement, installing guardrail, applying striping within the project area and reconstructing the streambed.

One of our original traffic plans called for U.S. 30 to be one lane with flaggers helping guide alternating directions of traffic. We’ve changed our plans to help prevent the long delays this would cause — now you can expect an eastbound detour.

U.S. 30 eastbound traffic detour.

Impacts
Plan ahead — eastbound traffic will detour on Colvin Road starting in May for up to 10 weeks.

• U.S. 30 is for westbound traffic only between the two Colvin Road intersections. The speed limit on U.S. 30 is 55 m.p.h. There is no local eastbound access on U.S. 30.
• Colvin Road is for eastbound traffic only, including for local residents. The speed limit on Colvin Road during the detour is 40 m.p.h.

We’re paving Colvin Road to prepare for the detour to start. We’re also trimming some trees, putting up new signs and cleaning the ditches. Expect construction noise while we make these improvements to Colvin Road.

Washington Department of Transportation is working on the Lewis and Clark (Longview) Bridge this summer!  Construction starts mid June and on July 16 they will close the bridge for up to 8 days...plan ahead.
