Crews will replace dozens of center divider posts on Highway 12 between Rio Vista and Suisun City Feb. 29 through March 2. Weather permitting, work will take place from 9 a.m. to 3 p.m.
The divider posts, also known as "channelizers," were installed about three years ago to improve traffic safety, but some of them are worn and damaged, according to the California Department of Transportation.
Portions of Highway 12 will be closed to traffic in both directions for 10 minutes at a time.
