Just got this email:
“After receiving input and questions from citizens at a meeting early this week and via subsequent email communication, Public Works staff contacted TxDOT for more information regarding the Parmer/Mopac intersection improvement project. City Engineers have reviewed the information and determined that the improvements may impact traffic at Duval and Amherst. As a result, the Duval/Amherst project will be placed on hold until after the Parmer/Mopac intersection work is complete. At that time, another traffic count will be taken to determine if the Duval turn lane is still justified.”
i.e. they listened to the concerns of people at the meeting and who sent emails, which is somewhat comforting. I’m still interested in how this project could have gotten to this state without neighborhood involvement, but for the issue of the turn lane itself, that is probably unlikely to resurrect.
