The Interstate 5 express lanes will remain open southbound until Monday, Jan. 3. The Washington State Department of Transportation said Thursday it that decision because of the continuing winter weather conditions.
With the cold temperatures, ice and snow can freeze and lock the express lanes gate mechanisms. In the past, attempting to operate the systems in these conditions has resulted in damage to the gates.
Keeping the express lanes open 24 hours a day also helps to reduce snow and ice build-up on the roadway.
WSDOT plans to return express lanes operations to its regular schedule on Jan. 3.
