Summer’s last holiday weekend is here. Drivers heading out the door today or tomorrow need to make sure they know what they’re driving into. Once the long weekend is over, construction and rock blasting closures resume east of Snoqualmie Pass.

Drivers can use the Washington State Department of Transportation’s (WSDOT) traffic volume charts this holiday weekend to “know before they go” and help time their travel on I-90. In particular, holiday travel congestion is expected between Cle Elum and Ellensburg and across the Vantage Bridge.

WSDOT and contractor crews will resume construction on Tuesday with rock-blasting closures planned Wednesday and Thursday. Rock blasting will close the pass a little earlier next week from 6:30-7:30 p.m. As always, eastbound drivers will be stopped at milepost 56 near Gold Creek and westbound drivers will be stopped at milepost 62 near the Stampede Pass interchange.

Drivers will continue to see slowdowns through multiple construction zones from the summit of Snoqualmie Pass to Vantage.
