Bridge to Everywhere: How to Keep International Trucks Moving While Expanding The Bridge of the Americas. Nov 12, 2024

International commerce depends on trucks crossing national borders regularly, reliably, and securely. Ports of entry like the bridges connecting the United States and Mexico in El Paso, Texas, are vital to both nations' economic vitality. But what happens when a major conduit like The Bridge of the Americas is closed for updating? Where does that traffic go? How can we keep those goods flowing without negatively impacting the surrounding community? We interview experts from TTI's Center for International Intelligent Transportation Research in El Paso to find out. | Bridges Connecting El Paso to Mexico | Texas-Mexico Border Transportation Management Plan

TTI experts Edith Arámbula Mercado and Charles Gurganus explain how maintaining the nation’s infrastructure is a lot like taking care of our own homes. The longer we postpone necessary upkeep, the higher the cost will be.

Policy, Priorities, and Possibilities. What might we see from new leadership at USDOT? Mar 16, 2021

Presidential administrations and their appointees come and go, but USDOT’s mobility mission remains constant.
