New Orleans Traffic Cameras: Watching I-10, the Twin Span, the Causeway and the Crescent City Connection

If you drive in New Orleans, you already know the city's geography is its traffic problem. The metro is wedged between the Mississippi River and Lake Pontchartrain, and almost every trip in or out funnels onto a bridge or a narrow interstate corridor. That's why a quick camera check before you leave is so valuable here — a single stall on a river bridge can lock up the whole city. The Louisiana Department of Transportation and Development publishes its New Orleans traffic cameras through the official 511 system, and our live Louisiana camera map gathers them into one searchable view so you can scan the chokepoints in seconds.

I-10 through the city

I-10 is the spine of New Orleans traffic. It enters from the west on a long viaduct past the airport through Kenner and Metairie, angles southeast along the Pontchartrain Expressway toward the Superdome interchange, and then runs east through the city and out across the lake. The I-610 bypass offers a cutoff north of downtown for through traffic that doesn't need the Superdome curve, and the I-510 spur branches off in eastern New Orleans. The cameras along these stretches are the ones to check for your daily commute — the Superdome interchange in particular is a reliable place for backups to form.

The Lake Pontchartrain crossings: Twin Span and Causeway

Two very different bridges cross Lake Pontchartrain, and they're not the same network. The I-10 Twin Span — officially the Frank Davis "Naturally N'Awlins" Memorial Bridge — is the roughly 5.5-mile interstate crossing at the lake's eastern end, carrying I-10 between New Orleans and Slidell. It was rebuilt after Hurricane Katrina destroyed the original spans in 2005, and as part of I-10 it's covered by LADOTD's cameras on the Louisiana camera map.

The Lake Pontchartrain Causeway is the other crossing — the famous 24-mile (23.83-mile) pair of bridges connecting Metairie on the south shore to Mandeville on the north, holding the Guinness World Record for the longest continuous bridge over water. The Causeway is run by its own commission rather than the state DOT, so it isn't part of the LADOTD 511 camera feed; for the I-10 lake crossing, the Twin Span is the one you'll find on the map. Both are long, low and exposed — exactly the kind of crossing where fog rolls in fast and visibility can collapse mid-span, so check the approaches before you commit.

The Crescent City Connection over the Mississippi

The Crescent City Connection — the twin cantilever bridges that carry US-90 Business over the Mississippi River, formerly the Greater New Orleans Bridge — is the city's signature river crossing and the farthest-downstream bridge on the entire Mississippi. It links downtown to the West Bank via the Pontchartrain Expressway on one side and the Westbank Expressway on the other, and it's slated to become part of I-49 South once that route is completed. With four general lanes each way plus reversible HOV lanes, it's one of the busiest crossings in the country — and a frequent congestion point. The 511 cameras on the approaches let you see whether the bridge is flowing before you join the queue.

Using the cameras for fog, congestion and evacuation

Three situations make the New Orleans cameras genuinely useful. Fog is the first: the long water crossings — the Twin Span and the river bridges — fog in quickly, and the cameras show you the real visibility instead of an optimistic forecast. Congestion is the second: the river crossings and the Superdome interchange back up daily, and a glance tells you whether to wait or reroute. And hurricane evacuation is the third and most important. When a major storm threatens, the state can run contraflow on I-10 out of the metro — reversing the inbound lanes toward Baton Rouge and beyond, with traffic diverted up I-55 toward Mississippi. Once contraflow is up, ramps and routes change, so scan the cameras early and follow official orders.

One caveat worth repeating: these are traffic cameras, not weather stations. The temperature and wind shown come from the nearest National Weather Service airport, so read them as the nearest airport's conditions alongside each camera, and trust the image itself for what's on the bridge.

Plan the whole trip

New Orleans is the southeast anchor of a long Gulf corridor. Heading east across the Twin Span and on toward the state line, switch to the live Mississippi cameras. Heading west on I-10 past Baton Rouge and Lake Charles toward Texas, pick up the live Houston cameras. For the statewide picture, start at the Louisiana camera map, and for everywhere else we cover, the road cameras hub is your home base. Five minutes of looking is the difference between a smooth crossing and an hour stuck on a bridge over the river.
