SNOQUALMIE PASS – Beginning September 8 through the first significant snowfall, drivers can expect up to 20-minute delays and rolling slowdowns on I-90 just east of Snoqualmie Pass near Keechelus Lake. Theses slowdowns are necessary for drilling crews to continue their work for the I-90 Snoqualmie Pass East - Hyak to Keechelus Dam project (I-90 project).

WSDOT will slow traffic periodically to a reduced speed between mileposts 57.5 and 59. The majority of these slowdowns will occur Mondays through Fridays during daylight hours with the exception of some weekends. Motorists should use caution, maintain the posted speed limit through the work zone, and are advised to watch message signs for specific traffic updates.

WSDOT maintenance crews will slow traffic in both directions as mandated by the Federal Aviation Administration (FAA). The FAA requires that a clear space be provided for helicopters carrying equipment over the Interstate for emergency landing purposes. Due to the rugged terrain, WSDOT and Crux drilling crews are using helicopters to deliver equipment to drilling locations along the mountain slopes.

WSDOT and Crux crews are using special drill equipment to collect rock core samples to determine soil and foundation conditions. Engineers are conducting this work to ascertain what methods are necessary to straighten sharp roadway curves, design, and construct the other improvements needed for the I-90 Snoqualmie Pass East project.

The WSDOT I-90 Snoqualmie Pass East project will improve I-90 by providing a safer, more efficient six-lane freeway from Hyak to Easton. The project will straighten roadway curves, replace old pavement, and reduce rock fall and avalanche hazards. WSDOT will also construct wildlife crossings over and under I-90 for the safe movement of wildlife and enhance wetlands and habitats throughout the corridor. Construction is scheduled to begin on the first five miles of the project in 2009. For more information, visit: www.wsdot.wa.gov/Projects/I90/SnoqualmiePassEast/HyaktoKeechelusDam/
