The construction or renovation of houses, offices and facilities involves quite a lot of work. The first job often involves moving any cables and pipes that are in the way. They have to go somewhere else, which means digging up the street at a different location. Occasionally, roads have to be closed to let construction traffic through. Or roads may be inaccessible for a time, for safety reasons. In cases like this, diversions will be put in place for pedestrians, cyclists and motorists. We make every effort to announce such developments in good time. In the immediate area, we do our best to help road users find the best alternative routes, by means of traffic signage.
