Sorrento to Miramar Phase 1
The Sorrento to Miramar Double Track Project Phase 1 is the first of two phases to be constructed between the Sorrento Valley station and Miramar Road. Phase 1 provides for a mile of new track, parallel to the existing track, south of Sorrento Valley Boulevard to the east side of I-805. A wooden trestle bridge built in the early 1940s also was replaced, and a new track crossover was installed south of Sorrento Valley Boulevard. The track is operated and maintained by the North County Transit District.
The construction contract was awarded in August 2011, meeting the Trade Corridor Improvement Fund funding deadline. Active construction began in June 2012 and the project was completed in March 2014.
