The Maestri Bridge (originally known as the Pontchartrain Bridge and later as the Watson-Williams Pontchartrain Bridge and the Five Mile Bridge) carries U.S. Route 11 (US 11) across Lake Pontchartrain between New Orleans and Slidell, Louisiana, in the United States. The bridge opened on February 18, 1928, as the first permanent crossing of Lake Pontchartrain. The 4.78-mile (7.69 km) bridge was the longest concrete bridge in the world upon completion. The bridge is 35 feet (11 m) wide and has two bascule-type draw spans for passing vessels and barges. The bridge was originally a toll facility, costing $1.25 for a vehicle with one driver, plus $0.10 for each additional passenger.
