Interstate 84 west of Hood River will see rolling slowdowns and delays in both directions after 12:30 p.m. Wednesday for rock blasting necessary to build the latest segment of the Historic Columbia River Highway State Trail. Rock blasting will take place between 12:30 and 2:30 p.m. The delays, which could last up to two hours, will be the fifth in a series of as many as seven blasts near milepost 53. This rock blast was originally scheduled for November 8, but was postponed. The blasting is necessary for construction of the Historic Columbia River Highway State Trail segment connecting Wyeth and Lindsey Creek. The 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.
