#19. SR-240, Yakima River Bridge at Richland

Two new bridges will be constructed to replace the existing four-lane bridge that carries state Route 240 over the Yakima River. Weakening bridge footing, caused by a critical scour problem, made replacing the bridge essential.

Route 240 functions as an important roadway through the Tri-Cities area, with traffic volumes on the highway expected to grow more than 3 percent per year. Updated bridge structures will help to meet the demand of vehicles in coming years.

The Yakima River Bridge replacement work covers a .59-mile portion of Route 240. Work includes approach slab construction and connections to the new, concrete, prestressed girder bridges into the existing highway alignments.

Additional lanes will tie into other ongoing Route 240 improvements to widen the highway and construct additional lanes between Richland and Kennewick.

The new bridges will include bicycle and pedestrian pathways. The bridge replacement contract also covers demolition of the old bridge.
