London's Tower Bridge is stuck open causing a nightmare for road users.
The bridge opened up earlier today to allow a ship to pass through, but it then failed to close again with people saying they have been waiting to cross for more than an hour.
City of London Police have urged people to stay away from the area. Posting on Twitter, the force said: "Tower Bridge is currently closed to pedestrians and traffic, due a mechanical fault.
"Mechanics are currently working hard to fix the bridge. Please find alternative routes."
According to reports on social media, those who were already on the bridge at the time were told via a public address system to find an alternative route.
On Twitter one person wrote: "Tower Bridge opened almost an hour and it hasn't closed back yet. It looks stuck and the two parts aren't symmetrical."
