CASCADE LOCKS, Ore. -- If you are driving Interstate 84 in the Columbia River Gorge this week, be ready for some big delays.

Tuesday through Thursday there will be rolling slowdowns to get the lanes reset and open at milepost 52. It's been down to one lane in each direction since the Eagle Creek Fire started in early September.

Oregon’s Department of Transportation says expect 20 minute delays on the interstate.

They've been repairing damage off of the eastbound lanes. To get traffic out of the way, ODOT diverted eastbound vehicles into one of the westbound lanes.

Tuesday starts the process of returning things to normal.

Drivers will be subject to rolling slowdowns that will allow crews to safely remove concrete barriers, and also restripe the pavement for the area affected east of Cascade Locks, along Shellrock Mountain.

ODOT urges drivers to be extra cautious for highway workers on the roadway doing the job.

All lanes should be reconfigured and open Friday.

The right lane of eastbound I-84 will remain closed for about a mile at milepost 53 through December. That is for the construction of the Historic Columbia River Highway State Trail segment from Wyeth to Lindsey Creek. That closure should be lifted Dec. 18.
