SANDAG's San Dieguito Double Track and Special Events Platform project will improve the operation and safety of the rail line in the LOSSAN Corridor between Solana Beach and Del Mar. The project will include double tracking, a bridge replacement, a special events platform at the Del Mar Fairgrounds, and other improvements.
The new double tracking from the Solana Beach trench, just north of Dahlia Street, to the north end of the Camino del Mar and Jimmy Durante overpass will result in a continuous 2.1-mile stretch of double track. Some realignment of the tracks to the east is required to get closer to the fairgrounds. All of the double tracking efforts in this project fall within the North County Transit District (NCTD) right-of-way, so the project does not require acquisition of new land to build the track.
The new San Dieguito Railway River Bridge will replace a more-than-100-year-old wooden trestle bridge. The new bridge and tracks will be elevated above the 100-year floodplain level to reduce potential operational impact during severe storms, high water levels (king tides), and flooding due to sea level rise.
The special events platform will provide a safe, reliable, and direct transit option for people attending events at the fairgrounds via Amtrak Pacific Surfliner and NCTD COASTER trains. This will also reduce vehicular traffic and congestion.
Other project improvements include signal and communications improvements, new turnouts, retained embankments, utility relocations, and upgraded drainage facilities.
