The Purple City plan for I-45

Check it out.

Should a major freeway plan consider the needs of cyclists? Of transit riders?

And if we’re going to tear down and reconstruct the entire downtown freeway network of the fourth-largest city in America, shouldn’t the final result have better geometry than the mid-century structures it replaces?

The PDFs below contain an analysis of Houston traffic patterns, a critique of the current plans for Downtown Houston’s freeway ring, and an alternate proposal. My schematic requires less right-of-way, creates a continuous managed lane network for commuter buses and BRT, and eliminates all left-hand exits, among other improvements.

The plan is here, and a detailed schematic is here. I’ve read the plan and recommend you do as well, there are a lot of interesting and worthwhile ideas in there. Tory Gattis has a bullet point summary as well as the news that this has attracted the attention of TxDOT, which can only be a good thing. I’m still trying to make sense of the schematic, which is quite detailed, so I don’t have any analysis to offer here, but I do hope that we hear more about this, and in particular that we have a much broader discussion about what we want to happen. As Purple City notes in the introduction of this proposal, what we have now is the result of design decisions that were made decades ago. The reality around us has made some of those decisions less than optimal for us. This is an opportunity to completely change downtown and its environs in a way that better suits the Houston we have now, or it’s an opportunity to lock in those decades-old decisions for years to come. This is why I harped so much on this during the election last year. I still think it’s the most important issue that got exactly zero attention from anyone other than me during the campaigns. What do we want these freeways that dominate our city core to look like, and how do we want to interact with them? We need to understand those questions and give them our best answers.
