Each tower consists of two tapered vertical reinforced concrete legs braced together with four reinforced concrete horizontal beams. The beams built by slip-forming, are hollow columns 155 metres high and vary from 6 metres x 6 metres at the base to 4.5 metres x 4.75 metres at the top. The inside faces of the legs are vertical and 18.4 metres apart.There is an electric lift in one leg of each tower for maintenance use. At deck level a reinforces concrete platform is cantilevered out on three sides of each leg to form the link between the main and side span footways.


   Each cable comprises 14,948 parallel galvanised drawn wires which, for the purpose of erection and anchorage , were divided into 37 strands. In addition, on the Hessle side span , there are a further 800 wires in each cable divided into 4 strands held by strand shoes both at the anchorage and at the tower saddles. With spinning and adjustment of the strands completed, the cables were compacted into a circular shape. After the complete suspended structure had been erected , the cables were coated with red lead paste, wrapped with soft steel galvanised wire and painted.


   The suspended structure consists of stiffened steel plate panels welded together to form a hollow box section 22 metres wide and 4.5 metres deep, with 3 metre wide panels cantilevering from each side. To maintain the shape of the section, and to form cross-girder webs, transverse diaphragms are fitted at 4.525 metre centres. The upper flange of the box forms the carriageways and the cantilever panels the footways and cycle tracks.The connections for the hangers are provided by brackets welded to the edge of the box of intervals around 18.1 metres.
At each tower and anchorage the deck is supported by two A-frame rockers. The rockers transmit both vertical and lateral loads while permitting longitudinal movement, vertical rotation and a small amount of lateral rotation of the deck. The upper edge of each rocker is pinned to a bracket on the end diaphragm of the box and the two lower ends to either the lower tower portal
or to the front of the anchorage. Expansion joints in the carriageway at each tower are of the rolling leaf type and between the side span and the abutment, of the compressible rubber type. Along both sides of each carriageway there are crash barriers consisting of four tensioned wire strands carried on posts at 4.525 centre and anchored at each abutment and the towers. A tube type parapet, 1.16 metres high, runs along the outside edge of each footway. The carriageways are surfaced with a 38mm thickness of mastic asphalt and the footways with a double dressing of rubber bitumen and 3mm chippings.
Four maintenance gantries give access beneath the bridge deck. The streamlined shape makes the deck aerodynamically stable and greatly reduces wind loads on the bridge.
