If you’ve ever spent time in the Rio Grande Valley, you know that the border isn’t just a line on a map. It’s a living thing. And right at the heart of that pulse is the Puente Internacional Expreso de Brownsville y Matamoros. Most locals just call it the "B&M Bridge" or the "Old Bridge," and honestly, it’s got way more character than the newer, shinier concrete spans further down the river.
It’s been there forever. Well, since 1904, technically.
Think about that for a second. This bridge has survived the Mexican Revolution, Prohibition-era smuggling, the rise of the maquiladora industry, and the shifting tides of international trade. It’s not just a way to get from Point A to Point B. It’s a historical landmark that happens to facilitate millions of dollars in commerce every single year. But if you’re planning to cross it today, you don't really care about 1904. You care about the wait times, the tolls, and whether or not you’re going to get stuck behind a line of idling semi-trucks.
Why the Puente Internacional Expreso de Brownsville y Matamoros is Different
Most international bridges are owned by city governments or federal agencies. The B&M is a bit of an outlier. It’s privately owned. Specifically, it’s a joint venture between the Brownsville & Matamoros Bridge Company, which is owned by the Mexican Government and the Union Pacific Railroad. This ownership structure gives it a slightly different vibe than the Gateway International Bridge or the Veterans International Bridge (Los Tomates).
Because of the rail component, you’ll occasionally see the literal movement of international freight trains cutting right through the area. It’s loud. It’s industrial. It feels like real work is happening.
The bridge connects downtown Brownsville—specifically near the end of Sam Houston Boulevard—directly into the heart of Matamoros, Tamaulipas. This makes it a favorite for pedestrians. If you’re a student at UTRGV or just someone looking to grab lunch at Garcia’s in Matamoros, the B&M is usually your best bet because of its proximity to the city centers. You can basically walk from a US university campus to a Mexican plaza in about fifteen minutes, assuming the lines aren't backed up to the street.
Dealing with the Wait Times
Let’s talk about the elephant in the room: the wait.

Waiting at the Puente Internacional Expreso de Brownsville y Matamoros can be a breeze or an absolute nightmare. There is no in-between. On a Tuesday at 10:00 AM? You might sail through in five minutes. On a Friday evening or during a holiday weekend like Semana Santa? You’re looking at an hour or more of staring at the bumper of the car in front of you while vendors walk between the lanes selling churros, bottled water, and those giant stuffed piggy banks.
Check the CBP Border Wait Times website. It’s not always 100% accurate—sometimes the "official" 20-minute wait feels a lot more like 40—but it gives you a baseline.
Also, keep in mind that the B&M has a SENTRI lane. If you have that "Trusted Traveler" status, use it. It’s a lifesaver. The bridge also uses a prepaid toll system called the "B&M Card." If you cross frequently for work or family, get the card. Fumbling for exact change or waiting for a receipt to print is the last thing you want to do when you're already running late for a meeting in Matamoros.
The Physical Reality of the Bridge
It's narrow.
Compared to the massive, multi-lane expanses of the Veterans Bridge, the B&M feels a bit tight. It’s a four-lane bridge, but when you factor in the pedestrian walkways and the proximity of the rail line, it can feel a little claustrophobic for drivers who aren't used to border crossings.
The tolls are a reality of life here. As of the last update, passenger vehicles usually pay a few dollars to cross south into Mexico. Walking across is significantly cheaper—usually around a dollar or so. Remember that you only pay the toll to the bridge company when heading South; when coming back North into the US, you don't pay a bridge toll, but you do have to deal with U.S. Customs and Border Protection (CBP) inspections.

Safety is the question everyone asks.
Is it safe? Honestly, it depends on who you ask and what time of day it is. The area immediately around the bridge on the Matamoros side is heavily patrolled and generally busy with commuters and shoppers. However, the Department of State often has travel advisories for Tamaulipas. Most people who cross daily for business follow a simple rule: do your business during daylight hours, stick to main roads, and don't make yourself a target. It’s common sense, but it’s worth repeating.
Logistics and Logistics
If you are shipping commercial goods, the B&M is a powerhouse. Because of the Union Pacific connection, it handles a massive amount of rail-to-truck and truck-to-rail transfers.
For the casual traveler, the bridge serves as a gateway to some of Matamoros’ best features. You’ve got the Mercado Juárez for shopping and the Teatro de la Reforma for culture. Brownsville itself has been leaning into its "Space City" identity lately with SpaceX nearby, but the B&M bridge serves as a reminder that the city’s identity is still firmly rooted in its relationship with Mexico.
One weird quirk? The bridge is open 24/7.
Some of the smaller crossings in the Valley close at midnight or 8:00 PM, but the Puente Internacional Expreso de Brownsville y Matamoros never sleeps. If you find yourself needing to cross at 3:00 AM on a Wednesday, the lights will be on, and there will be a CBP officer waiting to check your passport.

What People Get Wrong
People often confuse the B&M with the Gateway Bridge. They are close to each other, but they aren't the same. Gateway (the "New Bridge," though it’s not really new anymore) is just a few blocks away. If you see the line at the B&M looks like a parking lot, sometimes it’s worth looping around to see if Gateway is moving faster.
Another misconception is that you don't need a passport to walk across. You do. Or at least, a passport card or an enhanced driver’s license. While CBP officers are generally professional, they aren't there to hear your life story about why you left your ID at home. Have your documents ready before you reach the booth. It keeps the line moving for everyone.
The bridge is also a major hub for "bicycle commuters." You’ll see people with modified bikes carrying groceries, tools, and even small appliances. It’s a testament to the local economy's interdependence.
Actionable Tips for a Smooth Crossing
Don't just wing it. If you’re heading to the Puente Internacional Expreso de Brownsville y Matamoros, follow these steps to avoid a headache:
- Download the "B&M Bridge" App: Yes, they have one. It provides real-time camera feeds. If you see a line of cars stretching back past the toll booths on the camera, take that as your sign to wait or try a different crossing.
- Carry Small Bills: While they take cards now, the system can be finicky. Having five singles or a ten-dollar bill handy for the toll will save you from being "that person" holding up the line because the chip reader won't engage.
- Check the Rail Schedule: If a train is crossing, traffic can come to a standstill. There isn't a public "train schedule" per se, but locals know that mid-morning and late evening are high-activity times for rail freight.
- Know Your Duty-Free Limits: If you're bringing back vanilla, tequila, or medication from Mexico, know the limits. CBP will seize items that exceed the personal allowance, and you could end up with a fine that costs way more than what you saved at the pharmacy.
- Pedestrian is Often Faster: If you are just going to the immediate downtown area of Matamoros, park on the US side and walk. There are plenty of paid parking lots near the bridge entrance. It saves you the stress of driving in Matamoros traffic and the long vehicle lines on the way back.
The B&M Bridge isn't just a piece of infrastructure; it's the lifeline of two cities that are effectively one large community split by a river. Whether you're there for work, family, or just a day trip, respecting the rhythm of the bridge makes the whole experience a lot better.
Next time you're idling in that northbound lane, take a look at the architecture of the old rail trusses. It’s a piece of history that’s still working hard every single day.
