Have you reviewed the road closure order(s) These are often thoughtlessly drafted with a sole focus on motor traffic either assuming or ignoring the detail that pedestrian traffic will not make 2 mile diversion for a 200 yard closure, and will either march through the work-site or make an informal and often less safe arrangement without the legally specified arrangements for providing a pedestrian route around the work-site. Personal experience when I was arranging a bridge replacement saw the official arrangements suggesting a 6 mile diversion along an A-road and back lanes almost all of it without footways. I had to propose the pedestrian and cycling diversion (in the very middle of the village where people went under this bridge to get to the shops!)

So check out the plans for signage of the works (Chapter 8) and the arrangements for pedestrian traffic – including prams and wheelchairs, and at least 1.5m wide. Likewise for cycling, although perhaps with some parts where cyclists may have to walk. Then make sure this is delivered, as prescribed by the book.
