There is no programme for lighting all motorways. Lighting is provided where there is special need; such as, where there are frequent interchanges, where traffic densities are high and design standards restricted, at complicated interchanges, at steep hills, on sections prone to frequent fogs or where there is a night accident problem.

The cost of installing lighting when a three-lane motorway is being built ranges from £46,000 to £58,000 per mile depending on the mode of lighting and road layout. After it is open the costs range between £78,000 and £116,000 per mile.
