A pedestrian bridge that's barely a year old has had to close because of metal thieves. 912 metres of stainless steel wire were taken from Puddlers Bridge, which links Merthyr Tydfil town centre to Pentrebach. The theft happened last week.
The thieves have left a dangerous gap on the ramps leading up to the bridge, with local officials shutting the bridge as they're worried that someone could fall down onto the busy A4060 below.
Carwyn Morris, who designed the bridge, has said that the wire stolen was worth around £20 but it could cost £12,000 to fix. That is going to have to come from the highways budget. Councillor David Jones told ITV News that it's the equivalent of sorting out around 150 potholes.
They hope to have it open again in the next few weeks.
