About this Event
The concrete bridges that were designed and built during the early expansion of the motorway network from the late 1950s onwards, provide a rich, but slowly disappearing, design legacy. Some are well-documented, such as Owen Williams’ M1 bridges - few of which survive due to carriageway widening. The footbridges that remain range from utilitarian – chosen for ease of construction – to one-off experimental structures that have become landmarks for bridge-curious travellers. When the opportunity presents itself, observation of the architecture and engineering of these motorway structures can be a rewarding experience.
Helena Russell is a freelance technical journalist and engineer, formerly editor of Bridge Design & Engineering. In her talk she will look at some of the highlights of Motorway footbridge design, focussing on Hallingbury Footbridge on the M11 motorway [pictured]. As well as exploring the engineering aspects of the structure her talk will look at the bridge through the eyes of both the pedestrian and the road user and consider how they engage with the landscape and architecture.
She will also discuss some other examples of interesting motorway footbridges, to highlight an aspect of Britain’s motorway heritage that has scant formal recognition despite its contribution to the visual environment and contribution to technical innovation. Some of these structures have already been lost and those that remain are at risk due to planned widening schemes or ongoing maintenance demands. Very few are listed, but whether this offers anything other than wider recognition is questionable. Followed by a discussion as to whether these structures can and should be afforded greater protection.
For online attendance, please book your ticket before 18.00 on the day of the event. A link to watch the talk online will be sent to attendees before it begins.
