Northern Spire Bridge, Castletown, Sunderland

An earlier project for a new cable stay bridge crossing the River Wear between Castletown and Pallion, with two curving steel pylons reaching to a near-record height of 187m (613ft), was cancelled in 2013 as being too difficult and costly to build. This revised cable stay structure was designed by a joint venture between Roughan and O’Donovan, consulting engineers of Dublin, and Buro Happold, and was built by the Farrans Construction and Victor Buyck Steel Construction joint venture. It has a 105m-tall central A-frame pylon weighing 1,550 tonnes, supported by bored piles installed within a mid-river cofferdam, that was lifted into place by a floating crane in a 16-hour operation over two days. There are two main spans each 148m long, and the deck is 22.5m wide. The bridge was opened in 2018 and cost £117m. The River Wear Trail passes under the bridge on the northern bank of the river.
