NRHP Nomination Form"Originally called the "Elm-Main-Commerce Subway," the gateway was conceived as a "triple underpass" of streets, which afforded access to the western edge of downtown Dallas beneath the Union Terminal company tracks. To build the underpass, engineers regraded the area to slope gently down toward the west.
The Triple Underpass with the railroad bridge atop it was constructed of concrete with square balusters and distinctive Art Deco stylistic detailing.
The alignment of the tracks over the railroad bridge crossing the Triple Underpass was altered in 1990, with some old track removed. The street names still appear on the west portals of the underpass in large plain letters.
Debatably the most famous roadway feature in America. Witnesses observed Kennedy's motorcade, and the assassination, from vantage points atop the Triple Underpass.
