BELLEVUE – Eastside travelers should start planning alternate routes for their weekend driving, as the ramp from northbound State Route 167 to northbound Interstate 405 in Renton and northbound I-405 through Bellevue will shut down starting Friday night for critical repairs and maintenance work.

Both sections of highway will close at 10 p.m. Friday, Aug. 9. Crews will begin reopening northbound I-405 at 4 a.m. Monday, Aug. 12. All lanes and ramps, including the SR 167 ramp, will reopen by 5 a.m. Monday. This work is weather dependent.

The Washington State Department of Transportation urges drivers to “take five”—and take five minutes to check WSDOT’s online travel resources and map out weekend strategies, particularly drivers heading to the virtually sold out Mariners game on Saturday to watch Ken Griffey Jr.’s induction into the Mariners’ Hall of Fame. Drivers should consider taking I-5 as an alternate north-south route.

“We thank drivers for their patience yet again as we complete these important weekend closures,” said WSDOT’s Northwest Regional Administrator Lorena Eng. “We choose our closure times carefully, but we understand it’s not always easy for people to change their travel plans. We encourage those who can to carpool, use transit, or take other forms of transportation to help us prevent heavy congestion.”

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 ramp from northbound SR 167 to northbound I-405. The pipe, which is part of the stormwater runoff drainage system, will be replaced by a new, heavy-duty rubber pipe.

Drivers should expect delays on northbound SR 167 and SR 181 approaching I-405 and along the detour route.

I-405 concrete panel replacement and rehabilitation
Simultaneously, contractor crews on I-405 will continue work to replace the 50-year-old concrete panels. This time, they will work in the two right lanes between Southeast Eighth and Main streets in Bellevue – the length of a dozen football fields. Early Sunday and Monday mornings, crews will also grind and seal the concrete pavement between SR 520 and Northeast 70th Street in Kirkland. When the work is complete, drivers will experience a smoother ride with improved traction.

Drivers should plan for long delays on both sides of Lake Washington, particularly on I-90 near the detour routes, I-5 through downtown Seattle, and northbound I-405 where all traffic will exit to Southeast Eighth Street. Expect extra congestion on surface streets in and around Bellevue.
