H.P.
I commute from McKinney to Arlington about 3 times a week. I used to take the toll roads until my husband told me I was racking up $40/week in tolls, yikes!! Now I take 75 to 635, and yes the construction on 635 is a bummer. Fortunately for me I need to be at work at 630 am, so traffic isn't terrible yet. Coming home it's a little heavier, but still seems to take the same amount of time as when I take the toll roads. A little more traffic was worth the savings in tolls :)
