I-35E or I-45: Route Depends on Your Town
Ellis County has two main roads to Dallas, and they rarely back up together. Red Oak, Waxahachie and Italy use I-35E, which runs straight into downtown Dallas. Ferris, Palmer and Ennis use I-45. Midlothian has US-67, and US-287 connects Midlothian, Waxahachie and Ennis.
For a weekday trip to downtown Dallas, the worst I-35E slowdown is usually north of Red Oak, through Lancaster and DeSoto up to I-20. I-45 from Ennis is often steadier but goes in on the east side of downtown. Dispatch checks both before your pickup and sends the chauffeur on whichever road is moving.
