Drivers approaching the intersection of Interstate 405 and Interstate 90 in Bellevue should expect long delays starting at midnight on Sunday, Monday, Tuesday and Wednesday (July 29-31, and Aug. 1), as Seattle City Light crews work on power lines above the interchange.
The work is part of the state Department of Transportation’s South Bellevue I-405 Widening project. Crews will disconnect the power lines, place them on a new, taller pole, and reconnect them to the existing pole southwest of the I-90/I-405 interchange. During the operation, residents will not lose power.
Each night from midnight and 4 a.m., the Washington State Patrol will conduct intermittent, rolling slowdowns in both directions of I-405 and I-90 near the I-405/I-90 interchange. Work-related complications could produce up to 60-minute delays. During the slowdown, crews will close the following ramps to prevent traffic from entering the freeway:
- Interstate 90 ramps: Eastbound I-90 on-ramp from East Mercer Way, eastbound I-90 on-ramp from Bellevue Way, westbound I-90 on-ramp from 150th/156th Ave., westbound I-90 on-ramp from 148th Avenue Southeast, westbound I-90 on-ramp from Southeast Eastgate Way, westbound I-90 on-ramp from Richards Road/128th Avenue.
- Interstate 405 ramps: Northbound I-405 on-ramp from Southeast 44th Street, northbound I-405 on-ramp from 112th Avenue Southeast, northbound I-405 on-ramp from Coal Creek Parkway, southbound I-405 on-ramp from Northeast Fourth/Eighth streets, southbound I-405 on-ramp from Northeast Sixth Street, southbound I-405 on-ramp from Southeast Eighth Street.
Ramps will be closed at the same time at the beginning of each slowdown and will reopen as the slow rolling traffic escorted by the State Patrol passes each on-ramp.
To help prevent congestion, the state Department of Transportation is asking drivers to reschedule trips during the hours of the slowdowns, allow extra travel time or consider alternate routes.
