UDDATE | DECEMBER 4TH, 1PM: It looks like WSDOT has pushed the metering start date back one day – to Friday, December 6th. The signs on the on-ramp were changed today.
It’s not very often that road construction projects finish on time – especially when they occur in the fall – but it looks like the new, dedicated lane from Snoqualmie Parkway to the westbound I-90 on-ramp will open this week.
That means metering of the westbound on-ramp also begins this week.
Snoqualmie Mayor Matt Larson said 5th District Senator Mark Mullet and Representative Bill Ramos confirmed the new on-ramp lane [with new metering] would open on Thursday, December 5th. Larson said crews will complete some curb work in the spring when the weather is warmer.
Crews from Road Construction Northwest, Inc. of Renton began work in October. Modifications to the on-ramp include a dedicated right turn lane with no traffic signal for southbound Snoqualmie Parkway to westbound I-90, along with a dedicated ramp lane; a dedicated ramp lane for eastbound SR 18 drivers turning west onto I-90; retimed traffic signal for SR 18 to westbound I-90 to provide a longer green light for drivers; traffic metering for both lanes. The old weigh station return loop is being closed off with large cement barriers.
Even with the metering of the on-ramp, WSDOT says the additional ramp lane and retimed signal will result in shorter backups and improved traffic flow at this intersection.
The approximate $1 million project was funded by WSDOT, the cities of Snoqualmie, Covington, Maple Valley, and the Snoqualmie Tribe.
The I-90 on-ramps will be modified again and connected to the new I-90/SR 18 interchange prior to its opening. That major interchange improvement project is anticipated to finish sometime in 2023.
