Interstate 90 on the east side of Snoqualmie Pass is going to be closed for an hour each night at 8 p.m. starting today through Thursday.
Blasting near Gold Creek is being stepped up this week to help crews undertake the massive job of removing rock cliffs to widen the freeway from two to three lanes in each direction.
Traffic will be stopped at 8 p.m. each night for one hour to allow safe blasting. Drivers should plan for at least an hour delay during the temporary closures.
Blasting has been occurring since May mostly on Mondays and Thursdays at 8 p.m., but the contractor has been allowed additional blasts as needed.
In addition, traffic will be reduced to one lane in each direction 8 p.m. to 9 a.m. tonight through Saturday morning.
Slowdowns are also possible when equipment needs to move across traffic lanes.
A separate paving project near Keechelus Dam a short distance to the east will cause traffic to be reduced to one lane in each direction from 7 p.m. to 7 a.m. on Wednesday night through Saturday morning.
