PLACE: Dealey Plaza
Dallas, Texas
OWNERSHIP: City of Dallas, Texas
HISTORICAL BACKGROUND: This area (3.07 acres), called "The Front Door of
Dallas," was acquired by the City of Dallas for construction of the Triple
Underpass at Commerce, Elm, and Main Streets. The property was transferred
to the Park Board for maintenance purposes in 1936. Named Dealey Plaza,
September 19, 1935 (city minutes, City of Dallas, Dallas, Texas, Volume 8,
page 547) in honor of George B. Dealey, Publisher of the Dallas News and
long outstanding in Dallas civic affairs, the Triple Underpass was
officially opened on Friday afternoon, May 1, 1936. On March 2, 1940,
funds were appropriated to carry out improvements consisting of a program
for complete re-landscaping and new structures.
PHYSICAL DESCRIPTION: Dealey Plaza focalizes on incoming and outgoing
traffic between downtown Dallas and the major highway systems to the
north, west, and south of the city. The Plaza is bounded on the north by
Elm Street, on the east by Houston Street, and on the south by Commerce
Street, and on the west by the Triple Underpass.
The width of each concrete roadway through the plaza is 40 feet. The Main
Street roadway divides the Plaza and handles both eastbound and westbound
traffic. The Elm Street roadway flows traffic oneway to the west from Elm
Street, sweeping southwesterly toward the Triple Underpass. The Commerce
Street roadway flows traffic one way eastward in a southeasterly direction
from the Triple Underpass to Commerce Street. The declining angle, east to
west, of the entire Plaza area is approximately 3 degrees or about a
1-foot drop per 20 linear feet. The distance from Houston street to the
Underpass is approximately 495 feet by way of Elm and Commerce Streets.
When traveling by way of Main Street, this distance is 425 feet. The road
level at the Triple Underpass is approximately 24 feet lower than at the
Houston street level. Sidewalks, 10 feet wide, exist on the north side of
the Elm Street roadway, on the west side of Houston Street and on the
south side of the Commerce Street roadway.

situated in the Plaza area.
Steel and masonry structures enclose the plaza. At the northeast corner is

Dallas County Records Building, 93 feet high; the Dallas County Criminal
Courts Building, 124 feet high; the Old Court House, 73 feet high; the
Neeley Bryan House, 12 feet high; and the 179-foot-high steel
superstructure for the Dallas County Government Center. On the south side
of the Plaza, the United States Post Office Building rises to a height of
114 feet, and to the west is the railroad right-of-way, which passes over
