I commute in a van pool, and we normally get off at the 620 exit to drop people off at the NW park & ride facility. We have to drive about 2 extra miles and by the time we get onto 183, we are AHEAD of the traffic we were behind before exiting.
The lights in Cedar Park are so out of time, we take Lakeline to 1431. I called TXDOT and they said the 1431 / 183 intersection construction would eliminate the congestion. I told them they were full of it. There could be 10 lanes going each direction, but the light timing is not allowing traffic to flow.
If you want a number to complain to TXDOT, I'll give it to you.
I have changed my route. Lime Creek Rd (Anderson Mill) is now open all the way to 1431 and has 2 stop signs. I cut across and go that way now most of the time. Beats the Cedar Park traffic.
"That light, along with the short left turn lane to the mall is horrible. "
That light is unbelievable if you want to turn left. You're better off going straight through the light and then getting into the middle turn lane after the light. But then if too many do that, you're screwed again. I used to live off Lakeline, but now I'm down in the Arboretum which is a little better. just a little.
