Motorists may face brief delays in their morning commutes as roadwork to repave Highway 101 from the base of the Cuesta Grade to Atascadero continues.
The two-year state project is expected to conclude in spring 2012, according to Caltrans, as weather permits.
The project largely consists of overnight work from 8 p.m. to 5 a.m., officials said, but crews may continue a one-lane closure northbound until noon if the work carries on into the morning.
Crews usually stop the traffic-control measures between 8 and 9 a.m., officials said.
The current phase of the $41.8 million project includes work to chip away the aging asphalt on the highway so the base is ready for a fresh coat.
Chipped lanes will be open for periods of time, and Caltrans officials urge motorists to slow down and use caution on these sections of road.
Bridges — including Santa Margarita Creek Bridge, Atascadero Creek Bridge and the Traffic Way under-crossing — will also be widened and on- and off-ramps will be fixed.
The ramps include Highway 58, San Diego Road, Santa Rosa Road, Curbaril Avenue, Highway 41 and Traffic Way.
The project is being paid for with federal and state funds. The contractor is Papich Construction of Pismo Beach.
The American Recovery and Reinvestment Act is providing $37.2 million, and the state Highway Operation and Protection Program is providing an additional $4.6 million. The state-funded portion comes from California’s 18-cents-per-gallon gas tax and from truck weight fees, according to the state legislative analyst’s office.
