You don't have to tell me that, because I already see that starting. There is one intersection that crosses two access roads with the toll road above. There is no way more than two or three cars can make
both traffic lights going north. The cycle is way too short.
I've called TXDOT, and can't get the time extended for the north bound traffic, but the south bound gets over a full minute. 90% of the traffic is north bound. Go figure.
