A Caltrans project to install safety “rumble strips” along a 42-mile stretch of Highway 1 will begin with shoulder repairs Monday, May 2, stretching from 1 mile north of Hearst Castle Road in San Simeon to Highland Drive in San Luis Obispo, starting at the north end of the project.
Caltrans says shoulder work will be followed by lane/ramp closures on Highway 1 each week from Sunday night through Friday morning during the overnight hours from 8 p.m. until 6 a.m.
There will be one-way reversing traffic control with flaggers within the two-lane section of Highway 1 from north of Ocean Boulevard to north of Hearst Castle Road with up to 15-minute traffic delays.
Completion is expected in early summer.
Electronic message signs will be activated to inform the public.
The contractor for this $1.6 million project is Souza Construction of San Luis Obispo.
When a motorist’s vehicle travels over a rumble strip, it creates a vibration which is designed to enhance safety for travelers along the popular coastal route.
According to Wikipedia, rumble strips alert distracted or drowsy drivers that they are leaving the roadway or crossing the center line.
