The border ports between Mexico and the United States constitute an infrastructure of strategic bilateral character whose construction, operation, functioning and maintenance must be agreed upon and evaluated bilaterally. 

The Mexico-United States border is considered the most dynamic and complex in the world.  All of the issues of the bilateral agenda come together in this region, where numerous federal, state and local officials interact. It also links a number of institutions and organizations that represent the relationship between the communities both sides of the borderline.

The North American Free Trade Agreement (NAFTA) increased the historic ties between the border region communities, and posed new challenges as regards modernization of infrastructure, border crossings, updating procedures, health, and preservation of natural resources.

The border is defined as the area covering 100 km on either side of the borderline, and the length of the borderline between Baja California-California and Arizona is 265 km (165 miles). Baja California has 6 border crossing points by ground with California, and a maritime custom in the Port of Ensenada. The custom buildings for traffic by ground are located in the municipalities of Tijuana, Tecate and Mexicali, and border with the U.S.A. towns of San Ysidro, Otay and Tecate in the San Diego County, and with Calexico and Los Algodones in the Imperial County. All those border cross points have custom buildings and services.

The buildings are some of the most modern and large of our country, designed to be capable of offering their service during the next 15 years. Baja California has a great number of registered custom agencies that offer their services to contractors dedicated to operations of international trade.

It is calculated that the quantity of automobile border transit, be it tourism or commercial, was of 177,000 units per day in the year 2000. The Frontier Port of Tijuana-San Ysidro has the most traffic in our North border. 50,000 crossings by vehicle and 25,000 by foot occur per day.
