Southern Portal Broadway Tunnel

Work began on the Broadway Tunnel in November 1899. When opened in August of 1901, is was 760' long, 40' wide, and 22' high. (With the exception of the Fairmount Park Tunnel in Philadelphia, Broadway was the widest in the world—but then, Fairmount was a paltry 140' long.)

The tunnel was rebuilt in 1915-16, wherein its roadway was lowered, the roadbed lined in noiseless blocks, and its interior glazed in white tile.

The Broadway Tunnel was closed in June 1949. It and the hill that contained it were demolished for the Hollywood Freeway slot and the Broadway Tunnel became, curiously, an overpass.
