Later, when he became the Director of (Infrastructure?) at West Yorkshire Metropolitan Council, he kept the original calcs and drawings in a drawer in his office (no digitisation in those days). I'd say he was proud of it. He was a very capable bridge engineer and manager. <br />The design and construction predated me but I hazily remember two things about the bridge from a later visit to solve an internal drainage problem. <br />I think the cantilevered hard shoulders are not continuous longitudinally, but are relatively short lengths (widths of cantilever) butted up to one another. I never got to look at the calcs or the drawings. <br />The bridge is at the low point on a longitudinal road sag curve. It has an inspection manhole access in the hard shoulder near the low point. The lid allowed water in and (of course) the outlet holes - probably near the top of the inclinded legs eventually became blocked with debris. The internal boxes filled up with water (!). The perhaps temporary solution was to catch the water in a tray under the manhole lid and 'plastic gutter' it away to the outlet holes, from where it would drop into the valley below. It was felt important to keep water away from the external tendons thinly encased in concrete as pods on the floor/wall section surfaces inside the box. I moved jobs two years later. The bridge maintainers would still be faced with clearing these outlets from time to time. With all the danger and cost of lane closures to access the box, perhaps that is one of the reasons justifying the access platform? justanordinaryguyhttps://www.blogger.com/profile/08823291165152439339noreply@blogger.comtag:blogger.com,1999:blog-6470543006314152962.post-33715570962344076932014-07-28T20:04:18.115+01:002014-07-28T20:04:18.115+01:00Do you know the purpose behind having the inclined...Do you know the purpose behind having the inclined supports ?Cowardhttps://www.blogger.com/profile/07754877001171900260noreply@blogger.com
