Motorists in Renton, brace for impact: a complete shutdown of southbound Interstate 405 is on the horizon, commencing at the stroke of 11 p.m. this Friday, September 13, and stretching to the pre-dawn hours of 4 a.m. Monday, September 16; this announcement comes according to the Washington State Department of Transportation (WSDOT), with a narrow window, also carved out for northbound lanes with a four-hour closure pegged for midnight Sunday, September 15.
The shutdown aims to relegate traffic onto a new bridge, and pave the way—quite literally—for southbound I-405, not to mention the utility work primed for its northbound sibling; the routes that will feel the closure's clasp include the Coal Creek Parkway Southeast on-ramp, the Lake Washington Boulevard Southeast on and off-ramps, Northeast 44th Street on and off-ramps, and the Northeast 30th Street off-ramp, such details sprout from the WSDOT directly, these closed passages orchestrate a ballet of detoured avenues that will, WSDOT advises, falter under the typically robust traffic currents of I-405—hence, a call to the weekend warriors and daily commuters alike to plan ahead, sidestep peak hours, and where possible, delay travel that is not of the essence.
Even nighttime navigators must heed the closure siren, with northbound I-405 in Renton shuttering from Northeast 44th Street to Coal Creek Parkway Southeast, this curtain drop also includes the Northeast 44th Street on-ramp, the 112th Avenue Southeast on and off-ramps, and the off-ramp for Coal Creek Parkway Southeast; these closures, dictated by the choreography of maintenance and upgrade, carry a banner of progress—the stitching of a 40-mile-long Express Toll Lane system running through the I-405/SR 167 corridor, according to details from the WSDOT announcement.
Commuters should savvy up to the signs and delve into alternate routes beforehand as the detours on deck cannot shoulder the usual volume of I-405's weekend pulse, travelers wading through these diversions will follow the detour script laid out by WSDOT; this closure dance is part of the bigger choreography that is the I-405/Renton to Bellevue Widening and Express Toll Lanes Project, a strategic move aiming to forge seamless connectivity between the SR 167 High Occupancy Toll lanes and the already extant ETL system stretching from Bellevue to Lynnwood, pieces of this infrastructural tapestry destined to ultimately connect Renton and Northeast Sixth Street in Bellevue.
