The North County's Highway 101 repaving project will continue on the northbound lanes this week from the Highway 58 junction in Santa Margarita to Rosario Avenue in Atascadero.
Motorists can expect up to five minutes delays through Friday morning, according to Caltrans.
Crews with Papich Construction of Pismo Beach will be working from 8 p.m. to 6 a.m. with the option for lane closures through noon each day.
The paving work is expected "to be noisy at times for residents adjacent to the construction area," according to Caltrans.
Never miss a local story.
The $41.2 million project will repave all the lanes on Highway 101 from north of the Cuesta Grade to Traffic Way in Atascadero.
Slated for completion in spring 2012, it will also widen bridges and resurface on- and off-ramps.
