Two weight-in-motion (WIM) devices were installed near the north end of the international bridges that cross the Rio Grande at the City of Laredo (1993) and at El Paso (1994) with the purpose of collecting characteristic data about truck crossing the Texas-Mexico border going both northbound and southbound. Patterns of daily truck volumes, truck types, axle loads, and equivalent single axle load (ESAL) factors were all observed and analyzed for the duration of this research project. This data can be used to help assess the current and future impact of border-crossing traffic on the operation and maintenance of highway infrastructure in Texas. All the information gathered on various overloaded axle-types entering and exciting the country can be used to assist in monitoring and regulating these damaging loads, especially as regards NAFTA-induced traffic. The experiences recorded in this report on troubleshooting and the operation and maintenance of the two WIM systems should be applied to future WIM installation projects.
