Also put this in the airport thread. TxDot is suppose to start next year on a 30 million project to put in frontage 3 EB frontage lanes on 71 from Riverside to the airport entrance at Pres blvd. This will take the entrance/exit of the Parking spot and electric substation from the 71 mainlines and move them to the frontage. It'll also necessitate 2 direct connector ramps. The first ramp makes sense 183N TO 71E. The second one doesn't make any sense 183S TO 71E since the 183 South toll project just rebuilt that ramp.
Presumedly, the'll also incorporate the new DDI style airport entrance since that will require a new bridge so frontage traffic can bypass presidential blvd. As a reminder, here is that design:
They're also starting next year on the 71 overpasses, east bound and west bound frontage road project east of 130 at Ross and Kellam.
