FRENCH TOLL ROADS: 30 YEARS IN THE SUN

The article discusses the current improvements to the A8 French Autoroute toll road known as 'The Provencale'. Upgrading and widening the route is not straightforward as customer safety and trouble-free driving take priority. The third lane is being built as a corridor separated from the existing two lanes by temporary concrete barriers. All work that might impede traffic is stopped from June till September. Because of the need to design acoustic barriers, the wide variety of ground material and the hill terrain, the widening is costing as much as a new three lane autoroute through open country. Examples are given of the problems and novel techniques used to solve them, keeping the autoroute open to traffic at all times. A raft of expanded polystyrene was used as a base alongside a section where the original route had subsided by up to 800 mm since it was built. Five months disruption to traffic was avoided by building on underpass bridge 30m away from the autoroute and pulling it into position on a system of air states.
