I just drove to Houston from South Austin on 71 this afternoon. Honestly with two lanes traffic is not bad at all. It was far worse when I go on to I-10 in Columbus. 10 needs expansion far more than 71 needing to be a freeway. Houston was a total abomination for traffic heading INTO town.
Not bad at all. Everytime I drive it (and my in-laws live in south east Texas, so I drive it a lot) I nearly get into a fatal accident from driving 75 mph and someone pulls out from a driveway or cross street. Just because there are no stoplights doesn't mean its good to go. You still have side streets and driveways connecting directly to the mainlanes, not to mention blind hills, tight curves (yes, SH-71 still has a few of both) and houses placed way too close for a 75 mph corridor that has the look of a freeway but is not. It's not about time, it's not about speed, it's about the movement of trucks and cars at a speed and it to be safe to do so. It is hilarious to me to read everyone on this forum dismiss a need for SH-71 to be an interstate citing "it's a four lane expressway, it's good enough" or "it's 2.5 hours between the two, shaving off 15 minutes is not enough of a reason" and completely ignore the real reason this needs to happen. It's for the same reason any of the interstates were built. To keep traffic out of an Elinger, TX scenario (Oh, I love driving SH-71 to slow down to 55 in that town so I can relive 1960!) and so that long haul traffic moves safer. Everyone that loves to pile on this topic and say all is well in the world with the current status of SH-71 are the same people that jump on the thread about the at-grade crossings on West Texas I-10 and lament on how much of a travesty that is. It can't be both ways people!
An Austin to Houston interstate would definitely be more useful than I-2 and I-14, maybe even I-69. Connecting the capitol with the 4th largest city in Texas. However, from an article I've read, the reason TXDOT hasn't considered upgrading US 290 or SH 71 to interstate status is because of all the properties on the highway. Although, TXDOT does plan on removing all the stoplights on SH 71, so soon we'll see a stoplight-free corridor from Houston to Austin.
I hate those lame excuses. For some reason, the state had no issue buying up property for the right-of-way of the interstate highway system in the beginning and build over 3,000 miles of new freeway, but this 88 mile stretch, just can't do it! I know different era, but that's a lame excuse. As stated before and above, a stop-light free road is not equal to an interstate. Would you pay money to watch Metalica in concert, only to find out when they took the stage they were actually a Metalica cover band and the guys in the band were just some regular guys with 9 to 5s?
My vote has always been to upgrade SH-71. Everyone in Austin uses it to go to Houston more because it is wider and half of the trip to Houston is on I-10 if you go that way (not to mention it's faster). Upgrading it is cheaper because it's half the distance US-290 is. US-290 just always feels like a wasteland.
