A recent report by U.S. PIRG and the Frontier Group, “Highway Boondoggles: Wasted Money and America’s Transportation Future,” examines 11 of the most wasteful, least justifiable road projects underway in America right now. Here’s the latest installment in our series profiling the various bad decisions that funnel so much money to infrastructure that does no good.
The Trinity Parkway is a proposed nine-mile, six-lane urban highway (with tolls) that would run along the Trinity River through the heart of Dallas. Proponents claim that it is needed to relieve crushing regional traffic congestion that they expect will only worsen over time. But planning documents suggest that the $1.5 billion project would have only very limited impact on congestion and would be susceptible to flood damage.
A growing chorus of city leaders is asking whether the highway is really compatible with a Dallas that is experiencing major urban revitalization driven in part by expansion of public transportation and quality of life improvements that would be hampered by a vast new highway.
This project has been justified in part by forecasts of rapid growth in traffic in the project area in the decades to come. In most parts of the project area, however, planners are anticipating far greater growth in driving between now and 2035 than actually took place between 2007 and 2012, the most recent years for which traffic data are publicly available. Indeed, traffic actually declined between 2007 and 2012 at eight of 12 specific locations affected by the route where officials forecast traffic to increase by 2035.
