Begin I-310 South. Mile markers go from north to south on this Interstate. Exit 2 is 1 3/4 miles away, for US 61.
One mile to Exit 2 on I-310 South. Auxiliary signage indicates that St. Rose can be accessed via the next two exits.
One-half mile to Exit 2. More auxiliary signage, this indicating that Exit 2 allows travelers to access Louis Armstrong International Airport (airport code MSY).
Exit 2 peels off from I-310 here. The interchange between I-310 and US 61 is a four-level stack, one of only a few in the entire state of Louisiana.
Traveling through the I-310/US 61 stack interchange. Traffic from US 61 South to I-310 North and from US 61 North to I-310 South uses the higher of the flyover ramps.
Shortly after traffic merges on to I-310 from the US 61 ramps, signage for Exit 6 can be seen.
One mile to Exit 6 (LA 48, St. Rose/Destrehan). Also, END! the world's longest continuous viaduct.
One-half mile to Exit 6, as I-310 actually travels at ground level for a couple of thousand feet.
The best possible way I can explain Exit 6... it's reeeeally complex. As Exit 6 peels off, the 1 1/2 mile sign for Exit 7 (LA 18, Hahnville/Luling) appears. Before we can get to Exit 7 though, it appears something is in the way.
3/4 mile sign for Exit 7 on I-310 South as we cross the Hale Boggs Bridge, which carries I-310 over the Mississippi River.
Just a reminder... Exit 7, next right.
Exit 7 peels off from I-310 southbound. It's "reeeeeally complex" too. It's like breeding a SPUI and a folded diamond, then twisting the result until it's unrecognizable.
Advance signage for Exit 10 (LA 3127 North, Donaldsonville) passes by as we touch down “Across Da River.”
One mile advance signage for Exit 10 as I-310 gets back down to ground level again - and stays there. (For a little while, anyway.)
Half-mile advance signage for Exit 10.
Traffic bound for Exit 10 peels off to the right, as I-310 South prepares its approach to the end.
The end is only 1 1/4 miles away.
Traffic from LA 3127 South merges onto I-310 South as both highways prepare to end together. There's only a half mile of freeway left.
Traffic defaults onto the exit ramps as signs point out which lane traffic bound for eastbound and westbound US 90 should use.
END! I-310 South. This point also marks the END! of LA 3127 South.
Begin I-310 and LA 3127 North. The two break up very quickly after starting at US 90 near Boutte.
Another digrammatical sign for Exit 10 (LA 3127 North, Donaldsonville).
LA 3127 left-exits from I-310 here. LA 3127 is to the Westbank what Airline Highway (US 61) is to the Eastbank - a highway generally following the Mississippi River without being right close to it or following the river's bank exactly.
Just as traffic merges onto I-310 North from LA 3127 South, the one-mile sign for Exit 7 (LA 18, Hahnville/Luling) appears. The mileposts on this Interstate run counter to other north/south Interstates.
Half-mile sign for Exit 7 on I-310 northbound.
Traffic bound for LA 18 peels off here at Exit 7. LA 18 is the Westbank's "river road."
As I-310 begins to climb the Hale Boggs Bridge, the 1.5 mile guide sign for Exit 6 (LA 48, St. Rose/Destrehan) appears.
The one-mile guide sign for Exit 6 appears after traffic from LA 18 merges onto I-310 North.
As traffic descends from the top of the bridge, the 1/4 mile sign for Exit 6 is visible.
Exit 6 departs from I-310 North. LA 48 is the Eastbank "river road." This exit is, in a word, tortured.
The next exit along I-310 North is Exit 2 (US 61, Norco/Kenner). As the two-mile sign flies by, we also start on the World's Longest Continuous Viaduct.
One-mile guide sign for Exit 2.
Auxiliary information for Exit 2 is displayed.
One-half mile left to Exit 2.
Traffic bound for US 61 peels off as notice of the northern terminus is displayed in place of a pullthrough.
After traffic from US 61 merges on, all that is left is the connection with I-10, one mile away. Because most traffic is figured to be bound for New Orleans, the ramp to Baton Rouge is designated as Exit 1 and given only one lane.
Almost missed this one... Another digrammatical sign, about a half mile out.
Traffic partitions off for I-10 West (Exit 1) and I-10 East (curiously called “Exit 1A”). END! I-310 North.
