Starting Monday, Oct. 6, drivers on Highway 1 south of Guadalupe will encounter one-way traffic control as work begins on a $1.7 million repair project. A short-term traffic signal will be installed on Highway 1 near Brown Rd., two miles south of the intersection of Highway 1 and Highway 166. Travel will be reduced to a single lane in the area, with concrete barriers in place. Workers will be rebuilding a failed embankment, reinstalling a damaged guardrail, and refurbishing the shoulder area. If weather permits, the project is expected to be completed by the end of November.
