The San Diego County Board of Supervisors authorized a construction contract which will include replacing a guardrail along De Luz Road.The supervisors 5-0 vote May 8 authorized the advertisement for bid and subsequent award of a construction contract to install new guardrail segments and replace existing guardrail end sections throughout the unincorporated portion of the county. The bid package is structured with a base bid consisting of the minimum number of locations and a group of additive alternatives, or locations which can be added to the contract should funding permit. The De Luz Road guardrail is on the base bid list.Each year the countys Department of Public Works repairs, installs, and replaces guardrails and end sections along roads where guardrails have been damaged or where DPW has determined the greatest need to upgrade existing guardrails to current design standards. The base list has six locations while five locations are on the additive alternative list. The De Luz Road guardrail 100 feet north of Mile Post 5.0 will be replaced with one whose endpoints meet current standards.The $313,000 to fund the contract was derived from $250,000 of Highway User Tax Account revenue obtained from sales tax on gasoline and a $63,000 settlement from a Valley Center project which will cover 1,200 feet of guardrail along Mirar de Valle.The design for the guardrail replacements is complete, and since all work will be performed within existing county right-of-way, no right-of-way acquisition is needed. The construction is scheduled to begin in summer 2013 and be complete in early 2014.
