A cable-stayed swing bridge is under construction on Humberside that will carry the south orbital road over the River Hull. The bridge will be supported by six 84 mm dia spiral wound strands passing over a saddle surmounting A hollow steel mast rising above the pivot point. The cable supported main cantilever will deflect 475 mm in the unpropped condition, that is when the bridge is open to river traffic. When closed, this nose will be jacked on 2 movable bearings and the bridge will be locked through hydraulic controls. The south bridge carries dual, three-lane carriageways and footpaths over the river. The 18.5 M dia hollow concrete main pier is situated half in the east river bank and half in the river. The landing pier is a cellular concrete structure standing in the river to support the nose of the swing bridge and the link span with the west side viaduct. The 84 M long all-welded steel swing span is based on a framework of twin box girders. The orthotropic deck will be completed with hand-laid mastic asphalt. The cables will be erected and stressed once fabrication has been completed. The construction methods used for each part of the bridge are described. Completion is scheduled for October 1980. (TRRL) most important single accident factor was perception-hindering elements: hedges, parked cars, etc., were causal factors in 38,7% of accidents.
