Alternatives Evaluation Process
Alternatives Evaluation Criteria and Results
The alternatives evaluation criteria were used to compare the build alternatives and the no build alternatives’ ability to meet: the project purpose and need; the high-level engineering criteria such as constructability, right-of-way (ROW) needs, the complexity of utility relocation, and preliminary project costs; and an evaluation of environmental resource impacts.
Each alternative was reviewed under five criteria categories: purpose and need; feasibility, design and engineering; environmental resources; deck plaza local enhancements; and preliminary project costs.
Criteria within the Purpose and Need group included looking at each alternative’s ability to enhance safety, address demand and create a more dependable travel route. Criteria under the Feasibility, Design, and Engineering category included factors like constructability (such as risks and duration), utility conflicts, and drainage construction and risks. The Environmental Resources criteria, included an analysis of impacts to minority and low-income communities, historic properties, air quality, and traffic noise impacts. The Deck Plaza Local Enhancements group looked at each alternatives’ ability to accommodate deck plaza construction. And finally, the project costs criteria included an approximation of total project costs, as well as operations and maintenance costs for each alternative. The results of this evaluation phase was used to identify reasonable alternatives that will go through detailed analysis in the Draft Environmental Impact Statement.

The next steps in the project are as follows:
- Alternatives 2 and 3, and the No Build Alternative, will be further analyzed, including a detailed analysis of biological and water resources, community impacts, cultural resources, air quality and traffic noise impacts, hazardous materials, and other impacts.
- Results of these technical analyses will be shown and described in the Draft Environmental Impact Statement, including the identification of the Preferred Alternative, which will be made available for agency and public review and comment as part of the public hearing process.
- Following the 60-day public comment period, TxDOT will compile and respond to all public and agency comments and incorporate design revisions occurring as a result of the public hearing process.
- Ultimately, TxDOT will release the anticipated Final Environmental Impact Statement and Record of Decision, which will mark the end of the National Environmental Policy Act process.
