Transportation infrastructure in the border region is critical to both Mexico and the United States. San Diego and the rest of Southern California are home to major U.S.-Mexico trade corridors where goods pass through the region on their way to markets throughout the country and the world. Our transportation systems are also greatly affected by interregional commuting patterns and general travel.

SANDAG coordinates a number of comprehensive planning efforts to improve border transportation and infrastructure along the U.S.-Mexico border. Binational coordination and planning efforts include transportation infrastructure planning, forecasting, and data collection. Border-related transportation projects are included in San Diego Forward: The Regional Plan to accommodate the dynamic border transportation system. Such projects include: improving multi-modal access to border crossings, expanding freight rail service, and coordinating commercial vehicle crossings.

SANDAG is working with government agencies, businesses, universities and nongovernmental organizations on both sides of the border to maintain an efficient transportation system to facilitate the movement of goods and people throughout the California-Baja California region.
