San Dieguito Double Track

Photo Credit: Brett ShoaffThis project will replace the 96-year-old wooden trestle San Dieguito Railway River Bridge, add 1.1 mile of second mainline rail track south of Solana Beach, and add a special events platform at the Del Mar Fairgrounds for North County Transit District (NCTD) COASTER and Amtrak Pacific Surfliner trains.

The new rail bridge will consist of either one double-track structure or two single-track structures, but bridge capacity for at least one new track will be provided before the existing bridge can be demolished. Possible improvements include construction of new turnouts, signals, retained embankments, and drainage facilities. Some realignment of the tracks is being considered to accommodate the improvements and future rail needs. All of the double tracking falls within the NCTD right-of-way. The new bridge and tracks will be elevated above the 100-year flood plain to reduce potential damage to the rail line during severe storms.

The second main track will start in Solana Beach, just south of Dahlia Street. It will continue 1.1 miles south across the San Dieguito Lagoon, resulting in a continuous 2.8-mile stretch of double track. A universal track crossover also will be installed between the tracks to enable trains to reach the new platform from either direction.

The new special event platform will be located at the Del Mar Fairgrounds adjacent to its west parking lot. The platform will serve seasonal events at the fairgrounds, including the Del Mar racing season and the San Diego County Fair.
