In 1910, Beale Cut was bypassed by the Newhall Tunnel. Constructed by Los Angeles County, it was too narrow for two trucks to pass each other inside. As a result, in 1939, the tunnel was completely removed (or daylighted) when the road was widened to four lanes. Additionally, by 1930, a bypass road was constructed to avoid Newhall Pass via Weldon and Gavin canyons, which is the current route of I-5.
