Roger Evans, BSc, CEng, FICE, M.ASCE Roger Evans has been involved with the Humber Bridge project since 1981, most recently as Bridgemaster and Engineer. He advises the Humber Bridge Board on engineering and operational matters and manages the Board’s staff. His previous experience included bridge design and the supervision of construction works, particularly heavy foundations.

Humber Bridge

When opened to traffic in 1981 the main span of the Humber Bridge was the longest in the world. The bridge incorporated the latest technologies, including a box stiffening girder as developed on the Severn and Bosphorus bridges, and represented an extremely economical solution for a bridge of this magnitude. The use of concrete towers instead of steel was contrary to normal practice and led to further financial savings.

In large measure the shape of the deck and towers was controlled by aerodynamic considerations, with the end result being a structure which was both functional and elegant.

Funded from toll income, the bridge is owned and operated by the Humber Bridge Board who employ their own staff to operate the bridge. The presentation describes certain aspects of the design and gives an overview of the maintenance and inspection regimes.
