A bridge in the South Wales town of Ystradgynlais has ''collapsed'' following Storm Dennis.

The Teddy Bear Bridge has been left hanging after a section of wall near the walkway collapsed into the River Tawe following rising floodwaters. An adjacent road surface has also been left hanging in the air.

Residents were told the bridge could completely collapse at any moment.

One resident said they were ''concerned'' following the incident on Tuesday morning.

We thought that we had escaped the weather, the river was high this weekend but then it went back down. The bridge collapsed out of the blue. We are concerned - who knows what could happen. We have been in touch with the council and they are treating it as an emergency situation. Resident

Powys council has confirmed that they have closed the road until further notice.

Wayne Thomas, chairman of Ystradgynlais Town Council, called it an ''emergency situation'' and expressed his fear for residents nearby.

We have had past experience of flooding, it's a 4ft high wall and I expect the river will reach it."I have no doubt that this will affect the properties, it really is an emergency situation, I'm frightened for the people who live there. "The pub nearby has also just spent thousands of pounds refurbishing it." Wayne Thomas, Ystradgynlais Town Council

Engineers are due to inspect the bridge to decide what the next steps are.
