Interstate Five motorists should watch for frequent traffic control changes on Roberts Mountain the next few months due to paving work.

Dan Latham of the Oregon Department of Transportation said starting this Sunday, the two southbound lanes over the mountain will be separated by a barrier. Passenger vehicles will be able to use either lane while large trucks are required to move into the right lane.

Latham said at night, paving work will limit southbound traffic to a single lane from 7:00 p.m. to 7:00 a.m. Sunday nights through Saturday mornings. Schedules may change depending on the weather.

Latham said this traffic pattern will remain in place for about a month. During that time, northbound traffic will see intermittent single-lane closures for temporary striping, guardrail installation and paving.

Motorists are advised to drive with caution and watch for construction vehicles. A speed limit of 55 miles per hour is in effect for southbound freeway traffic on Roberts Mountain.

Latham said the $26 million project will add climbing lanes to the northbound and southbound approach to Roberts Mountain pass and pave five miles of Interstate Five. Construction began in February 2019 and is scheduled to be completed this fall.
