Interstate 310 Louisiana Highway 3127 North
Interstate 310 begins with Louisiana 3127 at a half diamond interchange with U.S. 90 near Boutte. The interchange has provisions for the eventual southward extension of Interstate 310 to future Interstate 49. As drivers merge onto the freeway northbound from U.S. 90, a pair of road stubs are in place for the future freeway. Photo taken 11/20/08.

Louisiana 3127 (River Parishes Highway) follows a multi-lane divided highway northwest eight miles to Louisiana 3141 (Mary Plantation Road) at Killona. Beyond there the state highway veers westward toward Edgard, St. James, and Donaldsonville. Photo taken 11/20/08.

Ascending on the Hale Boggs Mississippi River Bridge of Interstate 310 northbound. The span was the first high-level, long-span, cable stayed bridge in the world. The bridge was designed to withstand hurricane force winds up to 200 MPH and travels 1,222 feet from start to finish.1 The concrete roadway of the bridge was refurbished during a construction project in late 1999. Photo taken 11/20/08.
Interchanges exist on both approaches of the cable-stayed Mississippi River bridge. Exit 6, at the north end of the span, joins Louisiana 48 with Interstate 310. Louisiana 48 is also known as River Road as it straddles the north banks of the Mississippi between Jefferson Parish and Norco. Photo taken 06/10/06.

The last reassurance shield for Interstate 310 on northbound, which was replaced between 2008 and 2012. The freeway travels 1.8 miles of viaduct between U.S. 61 (Exit 2) and Interstate 10 (Exits 1/1A). Constructed during 1992 at a cost of $26.2-million, the bridges travel over prime tupelo and cypress swamp and thus required sensitive construction techniques.1 Photo taken 11/20/08. Second photo taken 04/20/12.
Diagrammatic overhead posted one mile south of the Interstate 310 stack interchange with Interstate 10 (Exits 1/1A). The elevated highway of Interstate 310 in conjunction with the next ten miles of Interstate 10 west, and the first 23 miles of Interstate 55, comprise the longest continuous elevated highway in the world at 38 miles. Photo taken 04/20/12.
Since the majority of Interstate 310 traffic is headed for the airport and city, two lanes are allocated for the eastbound Interstate 10 ramp (Exit 1A). Drivers taking the westbound flyover (Exit 1) will not see another interchange for ten miles (Interstate 55 north). Photo taken 04/20/12.
Interstate 10 westbound travels 61 miles to Baton Rouge and Interstate 12. Eastward Interstate 10 splits with Interstate 610 in ten miles. Photo taken 04/20/12.
