Dedicated Traffic Lane onto Westbound I-90 Could Open this Summer

This is a picture of the I-90/SR 18 interchange heading downhill on Snoqualmie Parkway.

Snoqualmie Mayor Matt Larson has been actively urging the Washington State Department of Transportation (WSDOT) to use a portion of the exit 25 weigh station as a temporary, designated on-ramp feeding from Snoqualmie Parkway onto westbound Interstate 90 during the I-90/SR 18 interchange improvement project construction.

In a letter to WSDOT last October, Mayor Larson stated a temporary lane would be consistent with WSDOT’s commitment to make low-cost improvements to manage congestion while interchange improvements are underway.

The overall investment would be approximately $1.2 million to be divided by a 50/50 match with the City of Snoqualmie. 

Senator Mark Mullet has secured WSDOT’s commitment to a $600,000 investment through a re-appropriation within the existing interchange project budget. 

The Snoqualmie City Council will discuss funding options for a potential match by the City of Snoqualmie.

If funded, the lane could be constructed as early as summer 2019. The lane may only be open for two years since the road alignments will change during construction.

This temporary solution would alleviate the current backups on Snoqualmie Parkway while also allowing for more efficient vehicle movements from northbound SR 18 onto the existing westbound I-90 on-ramp. These improvements would also greatly improve safety.
