Kirklees Viaduct M62

 

Kirklees Viaduct

M62 Motorway over River Calder, Calder & Hebble Navigation, and Calder Valley Railway


Grid Ref  SE 161 217

Constructed 1972 -1973

Following the collapse of the Cleddau steel box girder bridge at Milford Haven South Wales in 1970. and whilst I was working for  West Yorkshire County Council, I was drafted into a team of bridge engineers with Gerry Morgan and Ian Smelt, tasked with carrying out structural design checks to the box girder bridges currently being designed for the last section of the M62 Motorway in West Yorkshire to be completed.

In accordance with the requirements set down by the Merrison Committee appointed by the Department of Transport for Steel Box girder bridges (SBG6A) the team checked the design as it progressed and as the design rules  for steel box girders were continually updated by the Merrison team. Numerous visits to the Department of Transport in London were required for briefings on the updates.


As fabrication of the steel boxes was proceeding concurrently with the design and check, the end result was that some additional stiffeners had to be added to the external surfaces of the boxes. These stiffeners are visible on the box soffits adjacent to the column tops.


I have  included some old construction photographs on the next page.

The background to the Steel Box Girder Bridge Structural Design Checks and the far-reaching consequences is set out in an excellent paper in the Proceedings of the Institution of Civil Engineers by  Bridle and Sims
