Caltrans is advising motorists who use Highway 128 in Napa County of potential traffic delays beginning Monday due to a new bridge being constructed across Conn Creek.

The section of Highway 128 that will be affected by potential delays is between Conn Creek Road and Sage Canyon Road, near Silverado Trail.

Work crews will be completing road striping work and traffic lane realignment between 6 a.m. and 5 p.m. The bridge project is necessary because of the wear and tear on the existing bridge’s foundation from the current of the creek.

The new bridge will be wider to accommodate turning right from eastbound Highway 128 onto Silverado Trail. The construction will be completed by the end of the year.
