New energy-efficient tunnel lighting project continues in Monaco

The first stage of a project to replace outdated lighting systems in Monaco is nearing completion under The Rock, but Phase Two is about to begin on Boulevard du Ténao.  

Back in July, the Principality launched a lighting replacement and renovation project to upgrade the fluorescent and high-pressure sodium bulbs that currently illuminate the country’s tunnels. They are being replaced with energy-efficient LED lighting in line with Monaco’s overall switch to more environmentally-friendly practices.  

The first group of tunnels concerned run under the Rock. Here, some 1,340 new LEDs are being installed in the seven tunnels that make up the network. The work in this part of Monaco is nearly finished, although some road disruptions persist.  

Workers are on the job from 9pm to 5.30am in order to limit impact on daytime traffic, but by night, the majority of the tunnels are closed. Travel between Fontvieille and the rest of the Principality is only possible via the Liaison Marquet.  

The second phase of works is due to begin on 4th September. This part of the project concerns the Tunnel Saint Roman on Boulevard du Ténao. Here, state services will switch out 234 old bulbs for new over several weeks between early September and 20th October. The work will be carried out during weekdays from 8.30am to 4pm.   

“In order to limit nuisance, the work will be carried out with alternating traffic, with restitution of the two-way traffic outside the working hours,” says a government spokesperson.
