Texas DOT Seems Open to a Downtown Dallas Highway Removal

Will Texas embrace a model of mobility that works well for cities, instead of tearing them up with wider highways?

A new report from the Texas Department of Transportation indicates that at least in some circumstances, the answer may be “Yes.”

TxDOT last week released its “CityMAP” plan for urban highways in central Dallas [PDF]. Normally, you would expect a highway-focused report from TxDOT to be nothing but road expansions and widenings, with no regard for the neighborhoods that the highways cut through. But CityMAP is different.

The report calls for “integrated solutions reflecting statewide, regional and local shared goals that seek a balance for mobility, livability and economic development.” In other words, TxDOT is thinking about more than just moving cars.

Most significantly, the report indicates that TxDOT is seriously considering a highway teardown. Grassroots advocates in Dallas, led by planner Patrick Kennedy, have been mobilizing to remove I-345, which divides downtown Dallas from the Deep Ellum neighborhood, to make way for walkable development. The proposal gets a nod from TxDOT in the report.

TxDOT considers how tearing down the 20-lane highway and replacing it with an at-grade, six-lane road would affect traffic congestion and city life. The agency estimates that traffic delay on the surface street wouldn’t be any worse than if it spent hundreds of millions more dollars to bury the highway in a trench. (Although TxDOT says the teardown could increase congestion on surrounding roads.) Furthermore, TxDOT notes that removing I-345 would increase opportunities for urban housing, which could lessen the need for people to drive on highways in the first place.

The report does consider some costly highway widenings. But TxDOT no longer approaches every potential highway expansion as if moving motor vehicles is the only priority. CityMAP analyzes, for instance, whether relocating I-30 and making it an at-grade street — freeing up land for development by DART stations — might preferable to widening it.

Jay Blazek Crossley, former director of the Houston-based smart growth advocacy group Houston Tomorrow, said the document is “exciting.”

“I’m sure that the Dallas crowd is going to hate various details,” he said. But, he added, “This is very different than previous TxDOT reports.”

Dallas City Council Member Philip Kingston, who represents downtown, told Streetsblog that “the report is much better than anything TxDOT has done before” but that it still has some “crucial weaknesses,” and he suspects there was a split within the team producing it that led to some compromises.

Crossley said it remains to be seen whether this new approach will carry over to TxDOT initiatives outside Dallas. But he credits Kennedy and other advocates with spurring a discussion not only among locals, but the management of TxDOT as well.

“We want them to be a complex agency that has a lot of different priorities,” Crossley said. “I really hope that we can give TxDOT credit.”

Houston’s Big Chance to Turn Back the Tide of Car Traffic

There’s a lot riding on Texas DOT’s $7 billion plan for downtown Houston freeways. TxDOT has been working for more than a decade on a plan for the three highways that roughly form a circle around the city — I-45, I-10, and U.S. 59. Last April, the agency revealed a draft version of the plan, and another revision […]

Ta-da! Money for Highways Appears Out of Nowhere in Texas

TxDOT is broke, at least according to the agency’s actual records. But a funny thing tends to happen when someone in Texas wants to build an enormous highway — money appears, as if from nowhere. We saw this in the case of Houston’s Grand Parkway, the region’s third outerbelt and quite possibly the world’s largest […]

A Road Block for Texas DOT’s Highway Robbery Plan?

The Texas Department of Transportation loves big highway projects. In fact, right now, it’s pursuing a third outerbelt for Houston that makes the moon landing seem like a minor undertaking. It’s the black blotch that can’t even fit into the above infographic comparing the sizes of global ring roads. As a result of all this, […]

Texas DOT Raring to Build Money-Losing Toll Lanes

States seem to love expanding highways by adding tolled lanes, even when the money doesn’t add up. The 495 Express Lanes in DC’s Virginia suburbs lost $51 million last year, forcing investors to restructure $430 million in debt. Similarly, Maryland taxpayers are likely to be on the hook for the state’s new I-95 lanes, which […]

The Grassroots Campaign for a Highway Teardown in Dallas

Three years ago, Dallas-based planning consultant Patrick Kennedy and his friend, developer Brandon Hancock, started wondering why you couldn’t do a highway teardown in the Big D. They picked a highway: IH345, an elevated connector route between downtown and the Deep Ellum neighborhood. Then they thought, “Why not? Let’s do a study.” Between the two […]
