Caltrans is alerting motorists that the left lane of westbound Interstate 80 will be closed Dec. 6 from 8am-4pm from Magra to 1.5 miles east of Colfax.

Maintenance crews will be performing drainage work.

Drains for rain and snowmelt runoff are located along the median in this area of Interstate 80.

Because there are only two lanes on this three-mile length of Interstate 80, motorists are likely to experience traffic delays.
