A large concrete and steel leviathan is marking the the 50th anniversary of slicing a community in half. The Marylebone Flyover was officially opened on this day in 1967.

The flyover itself is just one part of the Westway, a 3.5-mile long elevated dual carriageway section of the A40 trunk road in west London constructed between 1964 and 1970.

The flyover was designed and built separately from the Westway, and this section is a bit of an oddity, as the Westway is elevated for most of its length, and comes down to street level just before reaching Edgware Road. That would have caused a gigantic problem as the Westway and Edgware Road meeting at a crossroads would have required a huge road junction and lots of traffic lights.

So, just as the Westway seems to have ended, there’s this last hurrah, as the flyover lifts motorists back skywards one last time before dropping them back down to a conventional wide road.

Despite its bulk and presence on what is a rather pedestrian unfriendly road junction, the structure still manages to pull off a deceptively delicate effect with single splayed support rather than a forest of unimaginative piles.

The underneath of the flyover has a shuttered construction finish, which is to say, the concrete was poured into moulds lined with planks of wood, so that the wooden grain would decorate the finished product.

The construction of the flyover also required the demolition of a swathe of housing and shops on the western side of Edgware Road in order to link it up with the Marylebone Road. A cinema, a church, and an entire street (Mitcham Street) of houses had to be torn down to make space for the flyover.

It also saw the demolition of the then nearly 100 year old Metropolitan Theatre, which was one of the city’s great old Music Halls, although at the time it was serving as a restaurant instead.

The flyover isn’t just for road traffic though, as where it comes down to street level and the underneath is bricked up, that’s for an electricity substation.

The flyover also has an under — an underpass for humans added at a time when subways under roads were all the rage.

In fact, they turned into homes for the homeless and hangouts for the addicted, and gentle folk stuck to the pavements.

These days there’s a move to close off these underpasses, and the one at Marylebone, nominally named after Joe Strummer, a musician of some note who one busked here, is likely to be bricked up as well.

It’s unlikely to be much mourned, with just two people hurrying through on my visit at the height of the morning rush hour. People avoiding it unless they need to cross multiple crossings in the land above.

Above, on the flyover itself, a sign still adorns the side of the flyover, installed at a time when politicians were delighted to open major new roads rather than apologize for them.

The flyover has always been a bit of a runt in the Westway project as far as its impact on society. The construction of the Westway spurred huge protests against it from local residents, and after it arrived, it’s uncompromising concrete structure inspired artists and musicians.

People seem to overlook the Flyover when talking about the Westway. It’s an overlooked punctuation mark to the long sentence of the main story. But punctuation marks are just as important.

Without this flyover, the road junction for both pedestrians and motorists would be a horrific sight.

At 50, the old structure is getting a bit of TLC, with structural repairs planned for next year. At the moment, there’s also a slowly fading work of art on the flyover, carved out of the grime accumulated in 50 years of road traffic.

It’ll never be loved except by us weird fans of concrete, but spare a smidgen of cake for the Marylebone Flyover.

Fifty years old today.

This website has been running now for over a decade, and while advertising revenue contributes to funding the website, it doesn't cover the costs. That is why I have set up a facility with DonorBox where you can contribute to the costs of the website and time invested in writing and research for the news articles.

It's very similar to the way The Guardian and many smaller websites are now seeking to generate an income in the face of rising costs and declining advertising.

Whether it's a one-off donation or a regular giver, every additional support goes a long way to covering the running costs of this website, and keeping you regularly topped up doses of Londony news and facts.

    Isn’t this flyover also heated – I remember seeing somewhere that there’s an electrical grid in the ramp concrete that can stop (or probably more like the case – could once – stop) the accumulation of ice.

      It was – like most 1960s/70s road ideas, they later decided it was a very poor idea.

    Part of the 1949 Ealing Film ‘The Blue Lamp’ was filmed here. See the scene where Dirk Bogarde attempts to create an alibi by attending the Metropolian Music Hall. Also the scenes filmed on the Edgeware Road when police are talking to barrow boys and secondhand clothes dealers to try and trace a raincoat worn at the murder of PC Dixon.

    Between 1964 and 1967 I was employed by Cementation as a Formwork Engineer and the initial design of the formwork to the flyover fell to me. Robert Myers was the site engineer he checked my calculations. He spent hours trying to find a mathmatical formula to calculate the horizontal and vertical ordinates to the soffit curve of the flyover. He was later told that the curve on the drawing was found by bending a length of curtain rod to give a pleasing shape. On site the curves were laid out on a stage using flexible battens
    The formwork was a series of ribs cut from three inch timber and supported on steel scaffolding. On the ribs were nailed sawn boards. I am responsible for a small deviation from the proscribed board layout.I regard my ‘mistake’ with some amuzement whenever I pass under the flyover.

    As a post script to my comment of the 15 june 2019. It is my belief that the formwork to the flyover is the largest piece of (one use only)formwork ever constructed
