BELLEVUE – Replacing a corroded drainage pipe and several hundred cracked concrete panels in just more than 50 hours isn’t easy, but that’s the mission contractor crews will undertake during weekend-long shutdowns of both northbound Interstate 405 through Bellevue and the northbound State Route 167 ramp to northbound I-405 in Renton.
Both sections of highway will close at 10 p.m. Friday, Aug. 9. Northbound I-405 will begin reopening at 4 a.m. Monday, Aug. 12. All ramps, including SR 167, will reopen by 5 a.m. that Monday. The Washington State Department of Transportation urges drivers to “take five”— take five minutes to plan ahead for congestion and prepare for delays, particularly those heading to the Mariners game on Saturday to watch Ken Griffey Jr.’s induction into the Mariners’ Hall of Fame. Drivers could also consider I-5 as an alternate north-south route.
“We need drivers to start planning now to keep traffic moving this weekend,” said WSDOT’s Northwest Regional Administrator Lorena Eng. “Carpooling, vanpooling and taking the bus are great options to beat the backups. If you have to drive this weekend, make sure your plan includes adding extra time to your commute.”
Culvert work under SR 167 at I-405
Contractor crews will work to decommission an aging 30-year-old metal drainage pipe located 12 feet under the SR 167 roadway. The pipe, which is part of the stormwater runoff drainage system, will be replaced by a new, heavy-duty rubber pipe and located directly under the ramp shoulder.
Drivers should expect delays on northbound SR 167 and State Route 181 approaching I-405 and along the detour route.
I-405 concrete panel replacement and rehabilitation
Simultaneously, contractor crews on I-405 will replace the 50-year-old concrete panels in the two right lanes between Southeast Eighth and Main streets in Bellevue – the length of a dozen football fields.
They will also grind and seal the concrete pavement between State Route 520 and Northeast 70th Street. When the work is complete, drivers will experience a smoother ride with improved traction.
Drivers should plan for long delays on Interstate 90 near the detour routes – northbound I-405 where all traffic will exit to Southeast Eighth Street and Interstate 5 through downtown Seattle. Surface streets in and around Bellevue will experience extra congestion as well.

Keeping traffic moving
WSDOT will do everything possible to help keep traffic moving during the weekend lane and ramp closures and the Mariners games against the Milwaukee Brewers:
