The Oregon Department of Transportation is shifting its scheduled rock blasts for the Mitchell Point Tunnel on the Historic Columbia River Highway Trail from Tuesday and Thursday to just Wednesday this week due to the Veterans Day holiday. Crews will do rock blasting and rolling slowdowns between 9 a.m. and 11 a.m. Wednesday. During the work, travelers on Interstate 84 in both directions between Cascade Locks and Memaloose State Park will be slowed down to create a 20-minute window where no traffic is near the blasting site. The regular Tuesday and Thursday schedule should return next week.
