Construction of a relief road to the north of Lyon will complete the city's inner ring road, linking the existing A6 Paris motorway to the north with the southbound A7 Marseille motorway to the west and with the two eastern motorways across the north of the city. Lyon has always considered itself a major European crossroads and aims to continue this after 1992 although Germany, Switzerland and Italy are also fighting for this position. Success hinges on the resolution of the city's traffic congestion problems. Through traffic uses the city centre and inner crossings and tunnels under the Rhone cause traffic jams. The Common aute Urbaine de Lyon's transport plan involves a 515.5 million pounds public transport programme and a 618.5 million pounds roads programme. A tunnelled route for the northern relief road was chosen as causing less disruption and demolitions. This will comprise two linked 900m sections and a third 3.7km section consisting of parallel tunnels carrying traffic in each direction. Surfacing briefly, traffic then runs into the longest and deepest tunnel passing 30m below the Saone. At the eastern end running is at surface level before crossing the Rhone on a 500m curved viaduct. Tunnelling will be by drill and blast and a specially adapted pressurised tunnelling shield. Finance has been arranged privately and the project should be completed in 1994. (TRRL)
