It’s a big job maintaining the nearly 2,000 of County roadway. Crews work year round filling potholes, improving water runoff by applying a thin skin patch on the road, clearing storm channels and under-the-road culverts, or sometimes installing new ones. Sometimes, however, a major road improvement is needed, such as widening a roadway from a two-lane to a four-lane to improve traffic flow and increase the roadway functionality. These projects can also include other improvements such as adding sidewalks, bike lanes or turning lanes; or even moving or improving utility lines during construction.
The Jamacha Boulevard Improvement is one such project recently completed by the Department of Public Works. It converted one and two thirds miles of existing two-lane roadway to four lanes between Huron Street and Sweetwater Springs Boulevard in Spring Valley.
The project was years in design, and required nearly two years for construction – done in two phases. One additional element constructed for the project was a large plywood sound barrier, required by the U. S. Fish and Wildlife to protect birds, such as the Least Bell’s Vireo. Now that the Jamacha project is complete, that wall is scheduled to come down in mid-September, after the breeding season ends on September 15th.
Besides widening the roadway, other project components included traffic signal improvements at the Sweetwater Springs/Jamacha Blvd, Pointe Parkway/Jamacha Blvd, Maya/Jamacha Blvd and Whitestone/Jamacha Blvd intersections; installation of a new water line for the Otay Water District; storm drain improvements; sewer system upgrades and moving the overhead utility lines to underground. Pedestrian, bike lanes and additional turning lanes were also added.
The roadway was paved with rubberized asphalt concrete which lasts longer and is much more quiet than standard asphalt concrete. So the next time you recycle your old worn out tires, realize those old tires are truly “where the rubber meets the road.”
The Jamacha Boulevard Improvement Phase 1 and Phase 2 combined project construction costs were $8.6 million, which was paid for by County road fund, TransNet sales tax, Proposition 1B, developer deposits, and contributions from utility undergrounding funds.
The project has greatly increased traffic flow on Jamacha Boulevard, and made the commute for many residents much easier and safer.
The Jamacha Boulevard Improvement Project is another example of the County of San Diego Department of Public Works' ongoing mission to continually improve our county infrastructure and roadway safety.
