OCEANSIDE–A portion of southbound Interstate 5 will be closed between Las Pulgas Road and Harbor Drive in the Camp Pendleton area from 10 p.m. Thursday evening to 3 a.m. tomorrow, according to the California Department of Transportation.
The temporary closure of the number one and two lanes will facilitate the movement of construction equipment for the replacement of the railway bridge over Santa Margarita River.
Additional closures are planned in the number one lane in the same location from Sunday, June 26, through Thursday, June 30, from approximately 9 p.m. to 5 a.m.
The Santa Margarita River Bridge is located in San Diego County, north of Oceanside and within the U.S. Marine Corps Base Camp Pendleton. This project will replace the existing steel truss single-track railroad bridge and its timber trestle approach structure with a new reinforced concrete double-track bridge and trestle approach structure.
The project is part of a larger effort by SANDAG to add a second track to the coastal rail corridor, also known as the LOSSAN rail line, from the Orange County line to downtown San Diego. Today, approximately half of the 60-mile corridor has been double tracked.
The single-track Santa Margarita River Bridge is located between two existing double track segments to the north and south. Adding the second main track on the bridge will allow trains to meet and pass, thereby improving travel times and on-time reliability for Amtrak, Metrolink, and freight services.
Bridge construction began in early 2010. It is anticipated that construction will be completed by mid-2012. The total cost of the project is estimated to be $40,630,000. It is being funded primarily from state transportation funds including Proposition 1B and the Traffic Congestion Relief Program.
SANDAG and Caltrans will make every effort to minimize disruption to the public during this closure. For more information on the Santa Margarita River Bridge replacement project, visit www.KeepSanDiegoMoving.com and click on LOSSAN Rail.
