Time lapse video of 'peace bridge' build over 18 months

Londonderry's 'peace bridge' has been officially opened by the NI first and deputy first ministers.

Started in January 2010, it cost £14m to build and its construction took 18 months.

The bridge covers a distance of 312 metres and will carry pedestrians and cyclists to and from the cityside and Waterside.

A camera placed on top of the City Hotel captured its 18-month construction.
