According to an old saying, the streets of London are paved with gold. A more accurate version would have them painted with howlers, typos and careless lines, as this gallery shows.
This worrying paintjob has graced the junction of Golden Lane and Old Street for some time now. To be fair, there is an arrow pointing left as well, but it's still a pretty dumb mistake to make.
Is it possible to shuffle a road like a deck of cards? It seems so, if this puzzling junction at Lancaster Gate is anything to go by.
You can't park on either side of this cycle track near Holloway Road. Are these London's narrowest double-yellows?
No, because here's an even tighter gap in the backstreets of Clerkenwell — close to where the old Guardian offices once stood.
More thin yellows, in Finsbury Park. OK, we can kind of get the point. Don't park your moped or very narrow car in the cycle lane. But surely there must be a more elegant solution?
You know how you sometimes put the wrong word into a crossword puzzle, then try to correct yourself by writing the proper answer in extra thick heavy ink over the top? Well, that happens on London's roads, too, as seen here in Catford. L-OK.
Write your own caption for this one — we don't want to sound like David Brent. Spotted in Hornsey Road.
Can you work out what's happened here? It looks like a utility company dug up a narrow strip of road, filled it in again, then dutifully repainted the road markings... but only the bit they'd damaged. A similar jobsworth touch-up was photographed by Ian Visits.
And finally, not so much a crappy road marking as an intriguing one. The putative underground canal was spotted in Uxbridge. One day, we'll go investigate.
