UCLA History: Old Tunnel (and maybe a new tunnel in the future?)
Above is a phote of the opening in 1930 of the Sepulveda tunnel north of UCLA. A story in the LA Daily News describes grand plans, nowhere near fruition, for such options as a new tunnel under the pass, a rapid busway, or a rail system. Of course, while construction on such options occurred, there would be gridlock of the type we currently have with the 405 widening. The story can be found at:
