Perryn Road footbridge over the A40, London by Grimshaw
[FIRST LOOK + PROJECT DATA] Grimshaw has completed this 32m-long footbridge over the A40 Western Avenue in Acton, West London
Designed with Hyder Consulting, the bright-yellow link replaced an ageing, damaged structure and runs diagonally over the busy dual carriageway.
The new bridge, which forms part of a larger redevelopment project that has also seen the overhaul of two major road bridges, is served by both ramps and stairs and provides improved access for pushchairs, cyclists and wheelchairs.
According to the practice, ‘the key design challenge’ was to build the bridge foundations on limited land next to the carriageway, a task made harder ‘by the quantity of utility services buried under the pavements’.
A spokesman said: ‘The new footbridge was designed so that the old one could remain in place until the new span was completed. This was installed in a single lift in one overnight closure of the road – the first ever planned complete closure of the A40. Once in place, this span and its new stairs were opened for public use, while the old footbridge was demolished to make room for the new ramps.’
