Border Crossing Freight Delay Data Collection and Analysis
FY 2001 Data Collection – Laredo Crossing
The World Trade Crossing (International Bridge 4) in Laredo, Texas is the most important truck crossing on the United States/Mexican border. Texas border crossings account for most of the truck traffic and the Laredo crossing alone represents over 60% of the truck traffic crossing the border between Texas and Mexico. Table 1 shows truck traffic for 2000 crossing the border from Mexico to the United States. The World Trade bridge crosses the Rio Grande River that separates Laredo, Texas from Nuevo Laredo, Tamaulipas, Mexico and provides a link between I-35 in the United States with such Mexican cities as Monterrey and Mexico City. Most (up to 90%) of the truck traffic at the World Trade Bridge in Laredo consists of "drayage." That is, short distance shipments between warehouses in Laredo and Nuevo Laredo. Typically, long distance trucks in either Mexico or the United States unload their cargos at a warehouse where it is transferred to a short haul truck for the trip across the border. Other shipments move directly from a factory near the border in Mexico to a warehouse across the border in Texas or from a warehouse in Texas to a factory in Mexico. These short haul trucks usually make up to three trips a day across the border. Figure 1 shows a map of the general region in Texas and Mexico that provides access to the border. Figure 2 shows the location of the World Trade Bridge within the city of Laredo.
Data collection activities took place at the World Trade Bridge border crossing on Tuesday October 30th, Wednesday October 31st and Thursday November 1st, 2001 for approximately ten hours each day. The times of data collection were selected to correspond to the daylight hours of operations at the bridge. The World Trade Bridge operates from 8:00 AM to 12:00 Midnight.
Inbound trucks (northbound) traveling towards the United States, leave Mexico pass through the export booths and proceed across the bridge into Texas and towards U.S. Customs. At Customs, the vehicles pass through primary inspection and after a secondary inspection, either proceed to special inspections (about 15% to 20% of the trucks) or leave Customs through the final inspection booths.
Outbound trucks (southbound) traveling towards Mexico, use Loop 20, which provides access to the World Trade Bridge. It can be accessed directly from I-35 or from the south from Mines Road. Loop 20 approaching the bridge is a new divided highway built specifically as an access road for the World Trade Bridge. Close to the border, the number of lanes expands to eight to enable the vehicles to proceed through the toll booths. The trucks cross the bridge and enter Mexico through import booths. Ordinarily, the Mexicans have up to ten booths operating. Most trucks pass through the import booths without much delay (no more than 90 seconds) and a small percentage are diverted to the secondary inspection facilities. At secondary inspection, trucks can undergo further papers checks and/or physical inspection at truck bays or in the parking area.
