A planned closure of Highway 1 south of Ragged Point has been pushed back a couple of days because of rain in the forecast.
The overnight closure was originally scheduled to begin Monday night and end Tuesday morning.
It has been rescheduled to Wednesday, March 11 and Thursday, March 12, from 11:55 p.m. until 6 a.m.
The location of the closure will be about two miles south of Ragged Point.
Emergency responders will still be able to get through, and electronic message boards will be activated to alert the public of the closure.
Caltrans says crews will be pouring concrete as part of a project to construct a viaduct and retaining wall along the highway.
The $4.1 million project is scheduled to be complete this spring.
