Border 4.0, mewer lines, more GDP. The smart crossing revolution is already underway

The competitiveness of the U.S.–Mexico corridor is decided every morning at the ports of entry. In 2024, the evidence was clear: more freight, more value, and more pressure on infrastructure. The Bureau of Transportation Statistics reported that Laredo surpassed 3 million northbound trucks from Mexico, a 3.1% increase versus 2023 and nearly half the volume of the entire southern border—proof of a system that works, but needs to move faster and with less friction. At the same time, cross-border trade averaged nearly $3.5 billion per day, underscoring that every minute lost in line carries a macroeconomic cost.

The 2024 pattern also showed modal contrasts. At San Ysidro, cars entering the U.S. from Mexico fell 6.4% versus 2023 (14.83 million crossings), a sign of elasticity driven by wait times, costs, and modal alternatives. In parallel, the number of buses crossing from Mexico into the U.S. declined 12.4% between 2019 and 2024, even as total bus passengers from Mexico rose 2.6%: fewer units, but better load factors and more efficient routes.

What’s working—and where should we accelerate? First, risk-based, tech-enabled lane management. On a “typical day” in 2024, CBP processed 1.15 million passengers/pedestrians, 270,800 private vehicles, and 88,582 containers; sustaining that flow requires reliable lanes (SENTRI at 15 minutes; Ready Lanes at half the time of general lanes) and expansion of programs like FAST for cargo. The Santa Teresa, NM, experience confirms that process engineering matters: the recent expansion added three commercial lanes and one FAST lane, with consistently shorter waits for trucks than in El Paso—a “laboratory” for depressurizing saturated nodes without sacrificing security.

Second, “smart” projects that blend dynamic tolling, real-time data, and binational integration. The new Otay Mesa East port—31 hectares and up to 20 lanes (10 for cars, 10 for cargo)—was designed to manage demand and target crossing times around 20 minutes through intelligent pricing and operations. The timeline shifted toward phased openings, but the design logic stands: pay for certainty and lower emissions.

Third, digitizing the crossing of people. In June 2025 the CBX bridge (TIJ–San Diego) became the first land crossing in the U.S. to use the EPP biometric system for re-entry, shortening processing for thousands of daily travelers and offering a replicable reference for intermodal terminals and cross-border bus stations.

Fourth, integrating inspections to avoid duplication. Unified Cargo Processing by CBP and SAT reduces redundant checks and cargo wait times; when deployed well, it frees capacity without pouring a single extra slab of concrete. The prioritization of “green” freight corridors—such as the Laredo–Monterrey memorandum announced in August 2025—adds a logistics-and-technology planning layer that lowers times and environmental footprints along a corridor powering the USMCA manufacturing heartland.

The gain isn’t just efficiency—it’s safety. Less time idling in line means fewer opportunities for incidents, more operational visibility, and cleaner risk profiles. It’s also public policy: when ports work, they puncture narratives of chaos and protect local jobs on both sides. Universities and research centers like UTEP, El Colef, and UC San Diego have documented for years the economic impact of shaving minutes off waits; the nearshoring arithmetic still holds: more “green minutes” at the border translate into higher local revenues and more resilient supply chains.

Where do we stand heading into 2025? With mixed signals. On the positive side, January 2025 brought a 7.9% year-over-year rise in U.S.–Mexico trade value and 10.2% more trucked cargo, validating that demand is there if operational certainty is guaranteed. On the risk side, tariff volatility in key sectors, urban bottlenecks leading to ports of entry, and tech fragmentation threaten to “give back” minutes the system had already gained.

My 2025 diagnosis is pragmatic: the potential will materialize if we do three things with no excuses. One, meet service targets (SENTRI at 15 minutes and Ready at 50% of general lanes) with public scoreboards by port and operational consequences when targets are missed. Two, standardize the digital layer: appointment systems and single pre-clearance windows for cargo, identity and biometric pre-check for people, traceability, and transparent dynamic pricing at tolled crossings. Three, lock in a binational project portfolio—Otay East, expansions in Laredo/El Paso/Santa Teresa, and cross-border BRT—with shared governance and metrics on time, emissions, and cost per crossing. The border already produces; what’s missing is treating time as a strategic asset. If 2024 taught us that every minute counts, 2025 must be the year we buy—and protect—those minutes with engineering, data, and coherent public policy.
