Transportation officials in Washington State are warning drivers about the “biggest closures” of the year coming to major travel corridors in the Seattle area this weekend.
Officials recently issued an advisory for a set of road closures they’ve dubbed “Monster Weekend” — “the biggest weekend of Washington State Department of Transportation (WSDOT) construction closures for the region this year.”
The road closures are set to begin late Friday, September 27 and last through early Monday, September 30, on State Route 520, through the I-405/SR 167 corridors, and on I-5 in Seattle and between Federal Way and Tacoma.
WSDOT says that the road closures will form a “monster” traveler challenge and drivers are advised that detour routes will not be able to accommodate normal traffic volumes. Drivers are asked to choose off-peak hours for travel or to delay non-essential travel until the road closures are lifted.
See below for more details from WSDOT on each closure.
SR 520 closure
The SR 520 closure stretches from I-5 in Seattle to 92nd Avenue Northeast in Clyde Hill on the Eastside and include all of the associated on- and off-ramps. The SR 520 Trail will also close for bicyclists and pedestrians across the lake. The highway and trail will close at 11 p.m. Friday and reopen at 5 a.m. Monday. Part of the SR 520 Montlake Project , crews will work on lighting and the fire suppression system under the new Montlake lid over SR 520.
Northbound I-405 closure
Northbound I-405 in Renton will be closed from Sunset Boulevard Northeast/Southport Drive (Exit 5) to Coal Creek Parkway Southeast from 11 p.m. Friday to 4 a.m. Monday. The following ramps will also be closed:
- Sunset Boulevard Northeast on-ramp (Exit 5).
- Northeast 30th Street on- and off-ramps (Exit 6).
- Northeast 44th Street on- and off-ramps (Exit 7).
- Lake Washington Boulevard Southeast on- and off-ramps (Exit 8).
- Coal Creek Parkway off-ramp (Exit 10).
During the closure, contractor crews working for WSDOT will shift northbound traffic onto a new bridge as part of the I-405/Renton to Bellevue Widening and Express Toll Lanes Project . A signed detour will be available. This work requires mostly dry weather and could be rescheduled if it rains.
Southbound SR 167 closure
Southbound SR 167 will be closed in Kent from SR 516 to South 277th Street beginning 11:59 p.m. Friday to 4 a.m. Monday. The following ramps will also be closed:
- SR 516 on-ramp to southbound SR 167.
- Southbound SR 167 off-ramp to South 277th Street.
Crews will be paving and striping sections of southbound SR 167. A signed SR 167 detour will be in place for this SR 167 Corridor Improvements Project closure. This work requires mostly dry weather and could be rescheduled if it rains.
I-5 overnight closures
Both directions of I-5 between SR 18 in Federal Way and 54th Avenue East in Fife will be closed overnight on Friday, Sept. 27 and Saturday, Sept. 28. Northbound lanes are closed by 10:30 p.m. and southbound lanes by 11 p.m. Lanes begin reopening at 7 a.m. on Saturday with all lanes open by 11 a.m. On Sunday, lanes begin reopening at 8 a.m. with all lanes open by noon.
Travelers headed to the Fife area should use the signed SR 99 detour route. People with destinations other than Fife should consider using regional routes including SR 18, SR 161, SR 167 and SR 512.
During this closure, WSDOT contractor crews will set girders for a new overpass crossing I-5. This work is part of WSDOT’s Puget Sound Gateway Program to complete SR 167 .
Mercer Street on-ramps to I-5
The Mercer Street on-ramps to both north- and southbound I-5 in Seattle will close beginning at 10 p.m. on Friday and reopen at 5 a.m. Monday. This work is part of the SR 520 I-5 Express Lanes Connection Project . Crews will use the shutdown to pave the ramp and adjacent shoulders.
