  New Orleans is served by Interstate 10, Interstate 610 and Interstate 510. I-10 travels east–west through the city as the Pontchartrain Expressway. In New Orleans East it is known as the Eastern Expressway. I-610 provides a direct shortcut for traffic passing through New Orleans via I-10, allowing that traffic to bypass I-10's southward curve.
  
  In addition to the interstates, U.S. 90 travels through the city, while U.S. 61 terminates downtown. In addition, U.S. 11 terminates in the eastern portion of the city.
  
  New Orleans is home to many bridges; Crescent City Connection is perhaps the most notable. It serves as New Orleans' major bridge across the Mississippi, providing a connection between the city's downtown on the eastbank and its westbank suburbs. Other Mississippi crossings are the Huey P. Long Bridge, carrying U.S. 90 and the Hale Boggs Memorial Bridge, carrying Interstate 310.
  
  The Twin Span Bridge, a five-mile (8 km) causeway in eastern New Orleans, carries I-10 across Lake Pontchartrain. Also in eastern New Orleans, Interstate 510/ LA 47 travels across the Intracoastal Waterway / Mississippi River-Gulf Outlet Canal via the Paris Road Bridge, connecting New Orleans East and suburban Chalmette.
  
  The tolled Lake Pontchartrain Causeway, consisting of two parallel bridges are, at 24 miles (39 km) long, the longest bridges in the world. Built in the 1950s (southbound span) and 1960s (northbound span), the bridges connect New Orleans with its suburbs on the north shore of Lake Pontchartrain via Metairie.
