A single lane of westbound Interstate 90 will be closed for two weeks as contractor crews work to repair the Raging River bridge.

The bridge is located just east of the Preston/Fall City off-ramp on exit 22. Work will be conducted around the clock to repair the roadway approaching the bridge to create a smoother ride for drivers.

Beginning on Sept. 30 and lasting through Oct. 5, the left lane of westbound I-90 will be closed. Then Oct. 7 through Oct. 12 the left lane will reopen and the right lane will be closed. During the closures speed limits will be reduced to 55 mph.

The repairs are part of the Washington State Department of Transportation’s repair work along I-90 between Issaquah and North Bend. The pavement on the 15-mile stretch of eastbound I-90 between the cities is more than 40 years old with roughly 73,000 vehicles using the portion of road daily. Construction and repairs are expected to be completed in the fall of 2019 and is estimated to cost $21.7 million.
