1887: M.L. Wicks and associates organize the Los Angeles County Railroad Company to build and operate a steam railroad from Los Angeles to the Pacific Coast somewhere in Santa Monica.
This system of grade-separated highways, designed for the safe and rapid movement of motor vehicles, is developed and planned by the Transportation Engineering Board.
The City Planning Department modifies it by adding the Whitnall Parkway in the San Fernando Valley.
The final form or design of the parkway system was influenced largely by the topography and physical characteristics of Los Angeles.
1994: Subway tunneling breaks through below the Wilshire/Vermont Station, formally tying together all of the Metro Red Line Segment 2 corridors: Wilshire, Vermont and Hollywood.
The Wilshire/Vermont Station requires an unusual tunnel configuration.
To allow for curves and changes in direction, one tunnel is built on top of the other where the tunnel approaches Wilshire from the north, instead of the traditional side-by-side configuration that is used throughout the rest of the Metro Red Line to date.
Four tunneling machines, each weighing about 200 tons, are used to complete the project.
