Don't get excited about Mopac changes...
I'm still not sure if it's willful ignorance or childish spite (because their grand plan to do the huge rebuild was rejected), but TXDOT still isn't answering the most important question of all with the managed lane proposal for Mopac, which is:
Since the managed lanes do not have dedicated on/off ramps,
when the 3 regular lanes are stop-and-go, how is a car or bus in the managed lane going to manage to get over to its exit without having to also come to a stop, and thus make all the other cars or buses in the managed lane have to stop too?
Note that I'm the only guy even talking about this; the local media, unfortunately reduced to just rephrasing press releases, just reports this as "hey, a new lane in the middle, hooray!" without bothering to think about how it will actually work.
