{{See also|List of streets of New Orleans}}
New Orleans is served by [[Interstate 10]], <!--[[Interstate 49]],--> [[Interstate 610 (Louisiana)|Interstate 610]] and [[Interstate 510]]. I-10 travels east–west through the city as the [[Pontchartrain Expressway]]. In [[Eastern New Orleans|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. Route 90|U.S. 90]] travels through the city, while [[U.S. Route 61|U.S. 61]] terminates downtown. In addition, [[U.S. Route 11|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 (Jefferson Parish)|Huey P. Long Bridge]], carrying U.S. 90 and the [[Luling Bridge|Hale Boggs Memorial Bridge]], carrying [[Interstate 310 (Louisiana)|Interstate 310]].

The [[I-10 Twin Span Bridge|Twin Span Bridge]], a five-mile (8&nbsp;km) [[causeway]] in eastern New Orleans, carries I-10 across Lake Pontchartrain. Also in eastern New Orleans, [[Interstate 510]]/[[Louisiana Highway 47|LA 47]] travels across the [[Intracoastal Waterway]]/[[Mississippi River-Gulf Outlet Canal]] via the [[Green Bridge (New Orleans)|Paris Road Bridge]], connecting [[Eastern New Orleans|New Orleans East]] and suburban [[Chalmette, Louisiana|Chalmette]].

The tolled [[Lake Pontchartrain Causeway]], consisting of two parallel bridges are, at {{convert|24|mi|km|0}} 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, Louisiana|Metairie]].
