COLFAX, Calif. October 14, 2018 – Caltrans is alerting motorists to anticipate delays on Interstate 80 east of Colfax next week due to continued construction work on the Truck Climbing Lane Project.

Caltrans will utilize both lane closures and “rolling block” escorts of traffic by the California Highway Patrol (CHP) through closure zones to remove a “crossover” lane shift and restore the interstate to its normal configuration across the Cape Horn Bridge.

The work is scheduled to start at 7 p.m. Sunday, Oct. 14 and continue until 7 p.m. Thursday, Oct. 18. Crews will be building the center median, paving and restriping.

This $50.6 million project is adding a three-mile truck climbing lane in the eastbound direction from the Long Ravine Underpass to the Alpine Overcrossing to improve safety and ease congestion through the steep grade where trucks, buses and larger recreational vehicles lose speed.

Motorists are encouraged to plan for delays and adjust their travel time accordingly. Weather or other unexpected events may delay or prolong the work. Please see project map for construction zone/closure area location.
