Tracks between Spring and Main Streets were eliminated in April 1926 to facilitate construction of the new Los Angeles City Hall.

[5] The following July, service to the Glendale and Montrose Railway depot was discontinued and the line was rerouted downtown to terminate at Spring and Court Streets.

Cars were briefly run through the new Hill Street Tunnel in 1939 before again being rerouted downtown.

[10][11] The final iteration of the L line began at Olympic Boulevard and Mullen Street and ended at the Civic Center, running via 10th (which was being rebuilt as Olympic), Country Club, Victoria, Hoover, 11th, Main, and Spring.

The western end of the line was cut back to Menlo Avenue in April 1940, shortly before the service was discontinued on May 26.
