This is a list of Rio Grande (Rio Bravo del Norte) bridges and other crossings from the Gulf of Mexico upstream to its source. This list of transportation-related items is incomplete; you can help by extending it.
The first bridge across the Rio Grande was a train bridge in Hidalgo, Texas, completed in 1914. It was replaced in 1972 with a new bridge that remains today. There are also two pedestrian bridges crossing the river: one in Reynosa, Mexico, and another in Columbus, Texas.
Here is a list of major bridges over the Rio Grande between Mexico and the United States:
Hidalgo, Texas - First Bridge (1914) - Designers: Carl Schurz and John A. Roebling - Construction began in 1913 but was halted due to World War I. The new bridge was finished in 1924. It has been replaced twice since then. Currently, it is being replaced yet again. The new bridge should be complete by 2020.
Port Isabel, Texas - Second Bridge (1972) - Designer: Eugene J. Kohn - The first bridge was destroyed by Hurricane Alex in 1970. It was a steel truss bridge with a main span of 180 feet (55 m). The new bridge is also made of steel and has a main span of 200 feet (60 m).
The Pecos, Devils, Chama, and Puerco rivers in the United States and the Conchos, Salado, and San Juan rivers in Mexico are the Rio Grande's main tributaries. Other significant rivers include the Gila River in Arizona and New Mexico, which flows into the Gulf of California; the Colorado River in Arizona, Nevada, and Mexico; and the Tijuana River in Mexico. The name "Rio Grande" comes from Spanish words meaning great river.
The river system that drains into the Rio Grande begins in the Rocky Mountains of North America. As the snow melts in spring, large amounts of water flow down from the mountains through torrents, gorges, and canyons. This is because most of these streams are glacier-fed or rain-fed rather than fed by creeks. They often become raging white water when there has been no recent rain and the snowpack is depleted. In the Southwest, this happens as early as April or May if there is not enough precipitation during the winter months.
As these rivers travel across the Great Plains toward the Gulf of Mexico, they gather more and more water until they are flowing at a tremendous rate. Most flow into the sea without being affected by ocean currents or tides because they are too wide for that current to have any effect on them.
The Laredo-Colombia Solidarity International Bridge is one of four vehicular international bridges located on the United States-Mexico border in the city of Laredo, Texas; it connects Laredo with Colombia near Anahuac, Nuevo Leon over the Rio Grande (Rio Bravo). The current bridge is a replacement for one that was destroyed by Hurricane Harvey in 2017. It is a continuous truss span that measures 1,000 feet (300 m) in length and stands 40 feet (12 m) above the river.
The Laredo-Colombia Solidarity International Bridge is part of the larger Pedro Joaquín Coldwell International Border Crossing project. The other three bridges involved in this cross-border project are the Laredo-Nogales Bridge, which carries traffic from Laredo to Nogales, Arizona; the Laredo-Reynosa Bridge, which connects Laredo with Reynosa, Mexico; and the Laredo-Dilley Park Bridge, which crosses the Rio Grande just south of Laredo and provides access to the community of Dilley, Texas.
The Laredo-Colombia Solidarity International Bridge has been called the "forgotten bridge" because it gets less attention than its neighboring bridges. However, the new Harvey disaster bridge also received criticism because it is made of concrete instead of steel.
In Port Isabel, there is a modest drawbridge that spans a boat canal. To allow boats to pass, one span of the bridge lifts straight up. There is also a lift bridge across the Neches River in Beaumont, Texas, and a railroad drawbridge beside Highway 59 in downtown Houston if you wish to add railroad bridges.
However, these are not true drawbridges in the traditional sense of the word. A true drawbridge would open completely above water so vehicles could pass under it. These are simply raised or lowered sections of bridge that can be used as access ramps for pedestrians or vehicles.
There are also some swing bridges in Texas, but they are not very well-known. One example is the Bayview Swinging Bridge near Rockport. This bridge connects Harris County with Jefferson County at the border with Louisiana. It consists of two parallel steel trusses with a gap in between that allows the passage of traffic. On both sides of the road, there are large signs warning drivers that if they try to cross this bridge when it is closed to traffic, they might get hit by a swinging bridge!
Another example is the Pedernales Electric Company Swing Bridge over the Pedernales River in Centralia. This bridge was built in 1918 by the City of Centralia as part of their electric company's system of power lines. Since then, it has been used by pedestrians and vehicles when needed.
The Rio Grande is either the fourth or fifth-longest river system in North America, depending on how it is calculated... Rio Grande.

There are 15 dams on the Rio Grande River in total, with the majority of them located in New Mexico. Flows remain substantial until they reach the Elephant Butte Reservoir in New Mexico. El Paso, Texas is located 125 miles downstream of Elephant Butte Reservoir and slightly upstream of the American Dam. The most recent dam to be constructed in New Mexico was the Theodore Roosevelt Dam. It went into operation in 1995 and serves mainly recreational purposes. There are plans to build another large hydroelectric dam on the Rio Grande near the Roosevelt Dam but these plans have not been completed yet.
The largest reservoir by volume is also in New Mexico - it is called Lake Powell. The United States government built this large reservoir as a storage facility for water from the Rio Grande River and other sources. Water is released from Lake Powell through canals or spillways that lead to locations such as surrounding states or back into the lake. For example, some of the water goes to Farmington, New Mexico for municipal use and some goes to Glen Canyon Dam for power generation.
Dams have had a significant impact on the ecology of the Rio Grande. They have altered the flow of water in the river and caused changes to species distributions. Fish populations may benefit from the presence of dams because they provide safe breeding grounds and food sources. However, other organisms may suffer due to the effects that dams have on their habitat.
