Due to concern expressed by Congress that the United States-Mexico border area was shouldering a disproportionate share of the costs of increased trade activity between the two countries, and that congestion problems related to expanded traffic were not being adequately addressed, the General Accounting Office (GAO) was asked to provide information and analysis on the following: (1) the nature of commercial truck traffic congestion at the southwest border; (2) the factors that contribute to congestion; and (3) the actions, including programs and funding, that are being taken to address these problems. Briefly, increased commercial truck traffic and the associated congestion at some border crossings, particularly older crossings that were built in downtown areas such as Laredo and El Paso, Texas, have taxed border community infrastructure. Lines of trucks - many of which are empty - waiting to enter the United States can run up to several miles during peak periods in the early to late afternoon, and the idling trucks contribute to air pollution and safety concerns in some major border cities. At the same time, crossings in remote and less accessible areas along the border are underutilized and less congested. Commercial traffic congestion at the U.S.-Mexico border is primarily caused by the high volume of vehicles at ports of entry that must be processed through facilities that have physical and technological limitations and cumbersome practices. Federal, state, and local governments as well as binational groups have responded to congestion at the border with a variety of initiatives. However, because facilities planning and port of entry operations take place in a complex political and economic environment characterized by competing interests and differing development priorities, these efforts collectively have neither been able to keep up with the rapid increase in the volume of goods crossing the border nor to alleviate congestion. |
