A lane closure will be taking effect on US 101 northbound near Gaviota for a paving project until late October.
A one-mile segment of the highway will be reduced to one lane, from the Gaviota rest area off the highway northbound to one-half mile mile north of the Gaviota Tunnel.
Caltrans crews will be continuing a paving operation, meaning the closure will be in place until late next month.
The rest area will also be closing overnight Monday through Friday, from 10 p.m. to 6 a.m. The project will replace the concrete barrier, as well as work on other mechanical and sidewalk repairs.
Caltrans plans to repave roughly six miles of the highway overall.
