When commercial and industrial crossings are constructed, the reinforcement beam is to extend 1 either side of cutdown. 2. Cutdown and splay extension to be constructed where the width is less than 9000 and the crossing width is less than This area is to be formed and surfaced to the Commercial/Industrial standard for all Commercial/Industrial vehicle crossings. This may be extended to where footpath commences. 4. The footpath within the crossing area shall removed and strengthened to match the vehicle crossing construction standard and then be surfaced with the same material as the footpath either side. 5. When crossing is a pedestrian cutdown use pedestrian / cycle cutdown shown in Drawing D VEHICLE CROSSING AND PEDESTRIAN CUTDOWN SET OUT D3.3.1
