The No. 2 westbound lane of Interstate 80 between Donner Summit and Colfax will be closed between Gold Run and Cape Horn in the “3-Mile Grade” area from on Aug. 10 from 7am to 4pm while Caltrans performs maintenance activities.

Approximately seven miles of the right lane will be closed to perform guardrail repair to a recently damaged section.

Because there are only two lanes on this length of Interstate 80, motorists are likely to experience traffic delays and are encouraged to plan for additional travel time through the area. California Highway Patrol will be escorting traffic through the work zone to keep speeds safe for Caltrans workers on this curvy, steep stretch of freeway.
