Gateway International Bridge, International bridge in Downtown Brownsville, Texas, United States, and Matamoros, Tamaulipas, Mexico

Gateway International Bridge is one of three international bridges linking Brownsville, Texas, and Matamoros, Tamaulipas, owned and operated by Cameron County. It crosses the Rio Grande as two flat deck spans, replacing the original 1926 steel arch bridge in the late 1970s. A highway sign gantry above the roadway displays green signs reading "Fort Brown", "Elizabeth St", "Int'l Bridge" and "Mexico", with a smaller "GATEWAY BRIDGE" sign.

The crossing opened in 1926 with a steel arch bridge, arches being a long-standing symbol of international gateways; matching arches were added to the Matamoros border station in the 1950s. Poorly maintained, the arch span was replaced in the late 1970s by two flat deck spans. Truck traffic has been banned since 1999, but the bridge still carries cars and pedestrians.

Locals call it "The New Bridge" (Puente Nuevo), a nickname kept from its 20th-century remodeling even though the Veteran's International Bridge is newer. The steel arches of the original 1926 design were echoed in the Matamoros Gateway border station built in the 1950s.

The bridge is open 24 hours daily and allows pedestrians free access to shops and attractions on both sides. It is important to bring identification documents as border controls are required on both sides.

The bridge's nickname, "The New Bridge" (Puente Nuevo), dates from its 20th-century remodeling and persists even though the Veterans International Bridge is newer. The original 1926 steel arch span was replaced by two flat deck spans in the late 1970s.
