"From November 2007 at at the end of February 2008, the layout of the circuit Bugatti U level of the turn of the Garage-green will be the subject of important work. The objective being to always better answer the safety requirements imposed by the International Federation Motorcylcist, this turn neither more nor will be moved less to be able to offer a broad release on the left side of the track. That amounts entirely shifting the entry of the turn, the loop and the exit towards the line of a score of meters. Financed by the Mixed Trade union of the 24 Hour old circuit of Mans, owner of the circuit, at the request of the ACO, at a total cost of 4,8 million euros, this work will have the originality to preserve at identical the drawing out of U so particular of this turn. 750 m of track thus "will move" towards the east, and the linear length of the layout of the Bugatti circuit will be slightly changed. In against part, this zone of the circuit will pass to 12 m broad, and the entry of the turn will profit from a bituminous mix extra width from 5 m, including 2 m covered of synthetic grass, and 15 m gravel vat. In the curve, the external gravel vat will pass from 52,50 m to 75 m, with 20 m of release out of bituminous mix. In addition, this new Garage-green falls under a total project of creation, side is Bugatti circuit, of a new entry éponyme, with some steps of the terminus of the tram. The spectators will be able to thus come directly to the entry from the circuit by public transport. An access for the people to reduced mobility is envisaged, as well as the possibility of establishment of a provisional platform of more than 2 000 places, and the startup of a new tunnel which will make it possible to pass under the track to go up to the Dunlop footbridge via the two already existing tunnels."
