Downtown Dallas is traditionally defined as bounded by the downtown freeway loop: bounded on the east by I-345 (although known and signed as the northern terminus of I-45 and the southern terminus of US 75 (Central Expressway), on the west by I-35E, on the south by I-30, and on the north by Spur 366 (Woodall Rodgers Freeway).
But, since 2000, the term “Downtown Dallas” has expanded to include Victory Park and Uptown/Turtle Creek Districts as well as past Central Expressway to the east in the Deep Ellum and Bryan Place Districts, past Interstate 30 to the south with the Cedars District, and jumping over Interstate 35E to the west to include the Design District and Lower Oak Lawn.
In total there are 11 districts that now form the definition of “Downtown”.
