The World Trade Bridge connects Laredo, Texas with Nuevo Laredo, Tamaulipas and is restricted to commercial vehicles, making it the workhorse of the busiest truck corridor between the U.S. and Mexico. Laredo has ranked as the top U.S. gateway for international merchandise trade in recent years, according to U.S. Census Bureau data. It is also the most active crossing on the Cargado marketplace, with more than 25,000 loads posted in the past year.

Heavy dry van volume in both directions, anchored by automotive, industrial, and consumer goods tied to Monterrey and Saltillo manufacturing, with steady flatbed and specialized freight alongside.
The World Trade Bridge is the main artery of U.S.-Mexico trucking. The span is restricted to commercial vehicles, according to the City of Laredo, and it ties the I-35 corridor on the Texas side to Mexico's Federal Highway 85D toward Monterrey, Saltillo, and the Bajio. Laredo has ranked as the top U.S. gateway for international merchandise trade in recent years, according to U.S. Census Bureau data, and most of that freight rolls across this bridge.
Operationally, Laredo is transfer country. Most loads run door-to-door on a through-trailer, with a transfer driver shuttling the trailer across the bridge while linehaul tractors swap on each side. Full transloading, where freight physically moves to a new trailer, is the exception here rather than the rule. See transbordo for how the two models differ. Mexican customs must clear at the port of entry, and customs brokers cluster on both sides of this crossing, so confirm yours works Laredo before you dispatch. If the lane is new to you, start with Mexico 101.
On Cargado, the World Trade Bridge is the deepest market on the network. More than 25,000 loads were posted and more than 35,000 bids were submitted on this crossing in the past year, with over 500 vetted carriers participating. The city of Laredo itself runs on this freight, with one of the largest warehouse and drayage ecosystems on the border.
Post the load on Cargado with its true origin and destination, not just the border stop, and matching notifies vetted carriers that run the Laredo corridor through the app, email, and WhatsApp. More than 500 carriers submitted bids on World Trade Bridge freight in the past year, so carrier depth is greatest here of any crossing. Carriers join and bid at no cost, which keeps the network broad.
The World Trade Bridge is Laredo's high-volume commercial span and carries the bulk of the corridor's trucks. The Colombia-Solidarity Bridge sits roughly 25 miles upriver, is owned by the City of Laredo, and is the designated route for hazardous materials and oversize loads. Many brokers treat Colombia as a relief valve when World Trade capacity tightens, and the customs broker on the Mexican side usually dictates which bridge a given load uses.
Cargado connects 250+ brokers with 2,000+ vetted carriers running Mexico and Canada freight every day.
