Texas I-10 Corridor Study

HNTB led a comprehensive study of the 880-mile I-10 Texas Corridor, the first of its kind to analyze the entire highway border to border in Texas. The project focused on identifying and prioritizing multimodal improvement strategies to meet the corridor’s diverse needs, spanning eight TxDOT districts, urban centers and multiple rural and suburban communities.

HNTB conducted the study in five phases, including virtual and in-person meetings, workshops and a multilingual corridor-wide survey. The firm’s efforts incorporated public input, stakeholder engagement, binational and bistate coordination and collaboration with the Department of Defense and maritime ports to meet military transport needs.

The firm’s role included performing technical analysis, traffic modeling and socioeconomic assessments. HNTB worked with a statewide analysis model and individual metropolitan planning organization models to establish consistent traffic volume forecasts, helping ensure a seamless transition between rural and urban areas. The study culminated in an implementation plan that outlined short-term, mid-term and long-term projects.

The resulting implementation plan identified 40 strategies and improvements to enhance infrastructure, technology and the movement of passengers and goods along I-10. Additionally, the plan identified 30 critical gap projects to address both current and future needs for I-10 and its connecting corridors, improving overall connectivity, mobility and resiliency across the state.
