M8 Harthill Pedestrian Bridge
The project involves building a footpath over the Lewes Road which, despite its speed limitations, can get quite busy throughout the day. Building this bridge over a road as important as this one can be quite a challenge and therefore I have decided to study this in detail.
The M8 Harthill Pedestrian Bridge, designed by Burohappold, had a very similar problem in the instance that it had to help the local residents cross the busy road safely and simply. It also uses a lightweight helical structure as per our design.
The bridge uses materials that maximise durability and minimise maintenance, something that would be also very apparent in our design. The construction of this bridge was completed in prefabricated sections which were then raised onto the piers from the road and fixed onto these supports.
If we take this piece of evidence and apply this to our design, we can see that this will be similar to how we can procure the construction of the footbridge. This will entail forming the supports before attaching the pier via a crane. This may entail a partial close of lewes road and deliver prefabricated sections to site.
