Sorrento Valley Double Track
SANDAG, in collaboration with NCTD and MTS, completed construction in November 2015 on the Sorrento Valley Double Track project, which added a mile of new double track north of the Sorrento Valley COASTER Station.
In addition, the project included elevating portions of the existing track bed, placing it above the 50-year flood level; replacing two aging wooden trestle bridges; building retaining walls adjacent to the tracks near the parking lots; and installing an embankment protection system along the western side of the track, adjacent to Los Peñasquitos Creek.
A new 81-space surface parking lot was added south of the station and along Sorrento Valley Road. There are now a total of 189 parking spaces to serve transit riders.
The project improved a critical section of the 351-mile LOSSAN rail corridor, which serves as a vital link for passenger and freight movements in San Diego County. The LOSSAN corridor is the second busiest intercity passenger rail line in the United States and is the only viable freight rail link between San Diego and the rest of the nation.
