Tower Bridge was closed this morning due to a police incident.
The bridge was shut in both directions on Wednesday morning after passers-by spotted a man on the railings of the bridge.
City of London police said the bridge reopened around 12.30pm.
The force had tweeted: "Tower Bridge is currently closed while we deal with a person who has climbed the structure. Updates to follow."
Around an hour later, it said: "The bridge has now been reopened. Thank you for your patience."
In August, traffic was brought to a standstill on the bridge after it was stuck open for more than an hour due to a mechanical fault.
