The McClure Tunnel is a tunnel in Santa Monica, California, that connects Pacific Coast Highway (State Route 1) to its junction with the western terminus of the Santa Monica Freeway (Interstate 10).

[3][4] The tunnel passes through the Santa Monica ocean bluffs,[4] underneath the Colorado Avenue–Ocean Avenue intersection and close to the Santa Monica Pier and southern end of Palisades Park.

[6] SR 1 then exits onto Lincoln Boulevard while I-10 continues east to Los Angeles.

The tunnel was built at a cost of $200,000 and connected Roosevelt Highway with Olympic and Lincoln boulevards.

The freeway connected to the tunnel in 1966, and in 1979 the tunnel was officially named in honor of Robert E. McClure, editor of the Santa Monica Outlook newspaper and a longtime advocate for the freeway.
