24th Street (National City) is a miss-named San Diego Trolley Station, it really should be called 22nd Street, a street which dead ends at the station's 156 space park & ride lot. 24th Street, a major street also named "Miles of Cars Way," for an extremely high concentration of auto dealerships, has an underpass beneath the tracks a bit south of the station. The station has the standard two extremely basic, ground-level side platforms with yellow tactile warning strips. These are connected by a central concrete grade crossing and another smaller crossing towards their southern end. The San Ysidro-bound platform has two red shelters covering benches for waiting passengers, while the Downtown-bound platform is alongside the parking lot which provides all station access and has the usual single large brown shelter with benches beneath.
From January 13, 2014 through September 2014, the station was completely rebuilt, passengers used temporary platforms under the trolley renewal project to have 6 inch high platforms replacing the former ones at ground-level. The new station has the standard renewed Blue Line station layout, with modern 6 inch high platforms. The track area is now normal ballast with 4 pedestrian crossings, 2 at each end of the platform that are step free, and two in the middle of the platform. Two larger cream-colored canopy structures on each platform provide more shade than the previous canopies. The parking lot was also redesigned as a proper transit center and bus bays on the edge of the parking lot. Three are now 6 total bus bays, 4 bus bays are directly along the Downtown San Diego-bound platform, and a further two along the southern side of the parking lot before Wilson Avenue.
