Around 8000 vehicles and up to 1000 pedestrians and cyclists crossed the old
bridge each day. The 4.4 metre carriageway width required traffic light control,
causing congestion and long delays at peak times, while the footpaths were only
1.5 metres wide.
The design solution accepted by ERYC consisted of a swing bridge
with a moveable span measuring 45 metres long x 14 metres wide – one of the
biggest to be built in the UK in recent years. A fixed approach pier on the
south side, 12 metres in length, aligns with the nose of the moving section, and
there is a shorter fixed pier on the north side. Unlike the Victorian bridge it
has replaced, which had a central pivot, the pivot on the new bridge is
positioned one-third of the distance from the tail, which has increased the
navigable passage when the bridge is open to shipping from 11.5 metres to 15.2
metres, despite the increased width of the bridge deck.
The regional ICE awards are judged by a panel of ICE members in
the region, including this year’s Chair Marian Hogg, a lecturer at the
Department of Civil and Structural Engineering at the University of Sheffield.
