Lamar St. to the west, and US 75/I-45 elevated highway to the east. The district is the spine of downtown Dallas, and connects many of the adjoining business and entertainment districts. The Main Street District excludes a small portion at the western end of the three parallel streets, which is where the John Fitzgerald Kennedy Memorial and Dealey Plaza are situated. That area falls within the neighboring West End Historic District.
