The Centennial Bridge is one of only two major bridge crossings over the Panama Canal. The other major crossing being the Bridge of the Americas. Two small service bridges stretch across the Panama Canal at the Miraflores Locks and Gatun Locks; however these crossings can only be used when the lock gates are closed. The Centennial Bridge opened in 2004 and was constructed to alleviate the traffic on the Bridge of the Americas and replace it as the route of the Pan-American Highway.
The bridge was named for Panama's centennial, which occurred on November 3, 2003. The Centennial Bridge crosses the Panama Canal at the Gaillard Cut near the Pedro Migual locks and is about 10 miles north of the Bridge of the Americas.
