Is Canal Street, at 171 feet wide, the widest street in the world? Many sources on the history of Canal Street will include the fact that this is the widest street in the world, sometimes in America, sometimes in New Orleans. The reason for the girth (and the name) is the planned but never built here canal.123

While I grew up across the lake, my mom grew up on this side. Canal Street in the 1960s was the shopping district. I learned from stories from my mom’s childhood about going shopping with her aunts on Canal Street, getting dressed up and taking the bus to spend the day going to the fancy shops and eating yummy food. It was a special treat to get to go to Canal Street to go shopping.
Canal Street was laid out around the turn of the 19th century and reached its most prominent time in the 1840s, according to Richard Campanella, when the Americans were flooding into the city and settling upriver from the French Quarter. Canal Street became the border between the two neighborhoods, Faubourg Ste. Marie and the Vieux Carre. Some say that the term neutral ground (still used today instead of median) originated here. This area was a neutral territory between the Americans and the Creoles, who some historians say had hostile relations.
I heard the fact about the widest street in the world and repeated it without question4. Canal Street is still often a sparkling magical place of my mom’s childhood in my memories. But the person I repeated it to, thankfully, questioned it. It came up again on a tour recently, where I had to break the news.
Widest Street in the World
A Google search for “widest street in the world” does not return Canal Street as the answer. The result, in Argentina, is 110 meters and 16 lanes wide, which is more than double the width of Canal Street. They built this roadway well into the 20th century though. It couldn’t have been the widest road in 1891 when the Library of Congress published images with captions claiming Canal Street as the broadest street in the world.

Broadest Street in America
You can find many sources showing Canal Street as the broadest street in America5. Wikipedia has narrowed this down further, “Canal Street is often said to be the widest roadway in America to have been called a street, instead of the avenue or boulevard titles more typically appended to wide urban thoroughfares.”6 This seems like it’s possibly only oft-repeated by tour guides as it doesn’t include a source for this claim, but using semantics like these does make it far more likely to be true.
Googling “widest street in America” returns many results too, including a street in New Hampshire that is 172 ft wide7 and one in Oklahoma that is “six ft short of being as wide as a football field”8. This could mean 294 ft (a football field is 100 yards or 300 ft long), 354 ft (360 ft long with end zones), or 154 ft (160 ft wide).

Widest Street in New Orleans
A Google search for “widest street in New Orleans” does return Canal Street in the AI results! AI is compiling answers from all over the web, so if it’s on the internet we can believe it, right?

The planned canal that was never here was actually built where the Pontchartrain Expressway/Boulevard is today, which is obviously wider to the naked eye than Canal Street, with a huge park as a neutral ground. According to Richard Campanella, the New Basin Canal was 60 ft wide with a foot print of 300 ft9. The photos demonstrate that construction took up all of the allotted space for the new road, more than double the space of Canal Street. But the road over the canal is called boulevard not street…
Semantics
One side of the former canal is called West End Boulevard and the other is Pontchartrain Boulevard/Expressway. Perhaps the separate names cause the distinction? Or maybe it’s because it’s a boulevard and not a “street”. I don’t know of any roadways named street that are wider than Canal in New Orleans, but I also am definitely not familiar with all the streets in New Orleans. Do you know of any wider streets?
Was Canal the widest roadway in the world at sometime? Possibly. Is Canal the widest street in New Orleans now? Maybe. That road in Argentina is an Avenida, not Calle, so it might not even outrank Canal. I think with enough qualifications we can probably make anything a superlative. Tour guides are especially good at this trick, so be careful about what you repeat 😉
