The following is a release from the Washington State Department of Transportation:

Drivers who take the eastbound Northeast 8th Street exit from northbound Interstate 405 should plan to take alternate routes Friday, Nov. 7, until Monday morning, Nov. 10, while crews work around the clock to complete emergency repairs on an approximately 30-year-old stormwater pipe beneath the roadway.

Contractor crews working for the Washington State Department of Transportation will replace a corroded section of the three-foot-diameter pipe, which has leaked and washed soil away under the shoulder of the ramp. The full-weekend closure of the ramp will also allow contractor crews to stabilize a nearby underground retaining wall before filling and repaving the ramp.

“We’ve been monitoring the area, and for the sake of drivers’ safety we need to get crews in this weekend to make the repairs,” said WSDOT Regional Administrator Lorena Eng. “We know closing the ramp is an inconvenience for drivers, but it’s important to get this work completed quickly and safely.”

The closure will start 8 p.m. Friday and last around the clock until 5 a.m. Monday. Some of this work is weather-dependent. If additional soil under the pipe and ramp continue to wash away, WSDOT may close the ramp before Friday.

Alternate routes

Drivers heading to east Bellevue from northbound I-405 should plan to use alternate routes. Two options for getting around the closure:

• Take the Northeast 4th Street exit from northbound I-405 and travel north on 116th Avenue Northeast to Northeast 8th Street.
• Take the Southeast 8th Street exit and turn left onto the Lake Hills Connector to Northeast 8th Street.

The westbound Northeast 8th Street exit from northbound I-405 will remain open.
