Roadway repairs on SR 18 finished ahead of wintry weather
SNOQUALMIE – Contractor crews working for the Washington State Department of Transportation will temporarily move the chain-up area on westbound State Route 18 to just east of the Raging River bridge in Issaquah.
Aecon, the contractor for the I-90/SR 18 interchange improvements project, will use the current chain-up location near Deep Creek for construction equipment related to stormwater treatment. Workers moved concrete barrier and relocated signs earlier this week to prepare the new space for westbound SR 18 travelers.
Prepared for wintry weather
With a highway widening project located just east of Tiger Mountain, it was vital that crews take advantage of the relatively dry weather in early December to complete several tasks ahead of winter weather, like pothole repair and restriping lane lines with reflective paint. Workers will continue to survey roadway conditions during construction and address issues as needed.
Whenever traveling in a work zone, drivers need to be patient, stay alert and follow reduced speed limits through the construction zone.
Widening SR 18 in stages
The I-90/SR 18 interchange improvements project is building a new diverging diamond interchange and widening about two miles of SR 18 between Interstate 90 and the Tiger Mountain summit. While this project is expected to be complete in 2025, a separate project will finish widening a five-mile segment of SR 18 to Issaquah-Hobart Road Southeast and is likely to finish in 2030.
