Request Dallas info: US75, I-45; or I-635; or avoid city?

If you come down 75 around noon just go straight thru Dallas. Except for about 2 miles of construction thru McKinney you should have no problem. 75 turns into I-45 downtown and continues on down to Ennis. Do not try to take I-635 around the city.
If you decide on Greenville to I-30 to Dallas you will take I-635 south to I-20 west to I-45 south to Ennis.
I live in McKinney, 30 miles north of Dallas, and have towed the 5er thru there a number of times, even during rush hour. US 75 I-45 straight thru is your best bet.
