Thorn wins Marseille tunnel contract

There's a new look to the Vieux Port Tunnel in Marseille coming along soon, and it's all down to new lighting. The Infrastructure Branch of the Marseille Provence Métropole (MPM) has awarded Thorn the contract to refurbish the 600m long immersed tunnel with 759 high output Gotthard fluorescent luminaires – in wattage ratings of 55W, single and twin.  The majority are dimmable.

The equipment will be installed during the first half of 2012 by electrical contractors Forclum, a subsidiary of Eiffage, the 8th largest construction group in Europe

The dual, two lane, Vieux Port Tunnel is the middle of three critical road tunnel links, carrying traffic along the Marseille coastline. Built under the city's Marina in 1967 it now requires major modernisation to handle the increased traffic flow and to improve safety.

Gotthard is ideal for this kind of specialised lighting where energy efficient, high illumination of low glare is required. Closure for maintenance purposes will be considerably reduced due to the highly sealed, robust nature of the luminaires.

To tackle congestion - Marseille is a bustling city of over one million inhabitants, and one of the few European cities in which several motorways terminate within the city - the MPM reoriented its major highways underground via new tunnels along the coastline. This not only enables thousands of road users to benefit from improved journey times though the city - and between Europe and the South - but allows economic redevelopment of the waterfront area to take place. These works, costing around €135 million, form part of the largest urban renewal project in Europe, and helped support France's oldest and second-largest city in winning the race to become the European Capital of Culture in 2013.

Thorn also lit the Joliette tunnel to the north, which opened in early 2011. At 5 meters below sea level and 1 km long the tunnel replaced the A55 viaduct and removed traffic from ground level. Altogether Thorn provided 391 Gotthard units – a mix of 55W fluorescent and 150W-250W high pressure sodium fittings – plus 20 low level Orus lanterns with Flat beam ® optics and 35W HIT lamps
