Check it out ! Only Two lanes each direction!
Yep and it stayed that way all the way until some point in the 1990's. I use to walk home from middle school and cross I-30 in Garland. School would let out at 3:50 so it would be some time after 4pm when I would get to I-30 and I could cross it no problem at all. Try that now days and you will be road kill.
