|Often times we’re asked, why do we need such a large project? Is it possible to build something smaller to meet the growing congestion problem?
Unfortunately, no. The traffic demand on this corridor is just too high. The project team is designing a project that meets the traffic demand along the corridor today and best manages the traffic projections of tomorrow. We are trying to keep the footprint as small as is responsible, and it’s important to us to design something that requires very limited right-of-way acquisition.
When we launched the study in 2012, the community told us that traffic congestion is a serious problem. In fact, 83% of survey respondents agreed that a goal of any proposed improvement should be to reduce congestion and manage traffic. TxDOT and the Mobility Authority are tasked with providing a real transportation solution that provides meaningful traffic relief.
Other times we’re asked, why do we have to have elevated structures as part of the project?
There are several reasons why we’re proposing elevated structures in Oak Hill. The first is that part of the project lies within a 100-year flood zone. In order to minimize impacts to the floodplain and to provide a reliable transportation corridor during a major flood event, the mainlanes need to be built above the floodplain elevation.
The second reason is that there is a large volume of traffic on US 290. Signalized intersections are not a long-term mobility solution when traffic volumes are as high, so we have to separate the mainlanes from the frontage roads at William Cannon and at SH 71.
We’ve heard from the community that it’s important that we minimize these intersections, and the project team is working hard to design the smallest footprint with the least impact on community values, such as the oak trees, Williamson Creek, businesses and the neighborhoods.
