A city as large and bustling as London is, naturally, full of roadways and streets. Some of them seem to stretch for miles at a time as they wind their way around the city. Some are impressively narrow, while some A-roads that start in London can take you to the other end of the country! But do you know which one actually takes the crown as London’s longest road?
That honour goes to a road over in South London: the Thames-hugging Rotherhithe Street.
Now, before everyone runs to the comments with refrains of “well actually…”, hear me out. – Rotherhithe Street is the longest continuous street in London that does not undergo any name changes. London is home to other vast expanses of road, like the A5/Edgware Road. But these undergo many a name change along their route.
Plus, we have to set some ground rules – one of which is that the road must be wholly inside London. Otherwise, who knows where you’d end up? We’re also deferring to pedestrian access and narrow dictionary definitions, with the distinction that a street “often has houses or buildings on both sides”.

Measuring 2.4 kilometres, Rotherhithe Street is not exactly suited for marathon training or long-distance hikes. But that doesn’t take away from the fact that, according to the above rules, it is the longest road in London.
Rotherhithe Street – aka London’s longest road
Rotherhithe Street starts (or ends, depending on which direction you take) from just outside Surrey Docks Farm. The street then meanders in a semi-circle, and takes you across two bridges, before petering out in a narrow pedestrian street that joins with Elephant Lane outside the King’s Stairs Gardens.
Along the road, you’ll find pretty parks, historic pubs, and even city beaches. Rotherhithe Street goes through several narrow points, with historic London buildings that speak to the area’s crucial maritime history towering over you as you stroll along its length.

If you don’t fancy wandering along the road for over two kilometres, much of Rotherhithe Street is mirrored by a shore-hugging Thames path that runs parallel to the street.
What to see on Rotherhithe Street
One of the most notable sights along Rotherhithe Street is the historic Mayflower pub – which is one of the oldest pubs in the city. Fun fact: it was purportedly made using wood from its namesake boat. Whether or not that’s true, we can’t say, but it’s still a delightful pub to enjoy a slice of history (and a pint or two!).
Other attractions along the road include the Brunel Museum, which tells the story of the Brunel engineering family, who built “the world’s first tunnel through soft ground under a navigable river”, and the Pageant Stairs Obelisk. The latter mysterious monolith bears no inscription or explanatory plaque – but it simply marks the Canary Wharf Estates boundary on the south side of the river.

And alongside plenty of pubs and historic sights, the road provides access to an impressive number of parks and green spaces. Pearson’s Park can be accessed from Rotherhithe Street and feeds into a large network of greenery that sits at the centre of the area. There’s also Durand’s Wharf, which provides a gorgeous bit of coastal park space. And, of course, there’s the Surrey Docks Farm, a working city farm and charity
Near where the road connects to Elephant Lane, at its easternmost point, you’ll even find the ruins of a former royal manor from the 1300s.
Other long London streets
Here are some other properly lengthy stretches of asphalt. Be warned though, they’re not exactly walkable…
- Edgware Road/A5: this remarkably straight stretch of road changes name multiple times and runs from Marble Arch to Edgware
- Green Lanes: forming part of the A105, this runs between Newington Green and Winchmore Hill.
- Upper Street: Carry on along Upper Street, which becomes the bottom portion of the A1, all the way to its end, and you’ll end up all the way over in Edinburgh, travelling along London Road! (After almost 700 kilometres that is…)
