Interstate 84 will see rolling slowdowns and delays in both directions in the area of milepost 53 sometime between 12:30 p.m. and 2:30 p.m. Monday for rock blasting necessary to build the latest segment of the Historic Columbia River Highway State Trail. The delays, which could last up to an hour, will be the fourth in a series of as many as seven blasts in the coming weeks at the location between Cascade Locks and Hood River. The blasting is necessary for construction of the Historic Columbia River Highway State Trail segment connecting Wyeth and Lindsey Creek. At Lindsey Creek, blasting will create room for the new segment of trail in the existing rock slope. This work is located in the same area where eastbound traffic is temporarily diverted into one lane of westbound I-84 due to fire debris removal activity from the Eagle Creek Fire.
