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.
