Delays to worsen at Snoqualmie Pass until snow hits


Yakima Herald-Republic

Workers will nearly triple the pace of drilling on the slopes above Interstate 90 near Snoqualmie Pass.

Until the first significant snowfall, drivers can expect more frequent 20-minute delays and rolling slowdowns on I-90 near Keechelus Lake because of increased helicopter trips over the interstate, the Washington state Department of Transportation announced Tuesday.

Transportation workers will frequently slow traffic to a reduced speed between mileposts 57 and 59. The slowdowns will occur as needed seven days a week.

Those driving over Snoqualmie Pass are urged by transportation officials to dial 5-1-1 or visit www.wsdot.wa.gov for current construction information. While on the road, drivers should tune to AM 1610 or AM 530 and watch for messages on electronic highway message signs.

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

 The I-90 Snoqualmie Pass East Project is expected to improve I-90 by providing a safer, more efficient six-lane freeway from Hyak to Easton. The project is designed to straighten roadway curves, replace old pavement and reduce rock fall and avalanche hazards. The state 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.
