Traffic information

What is the current traffic situation?

For vehicular traffic:

The affected sections will be closed off to traffic, one by one, as the project progresses. At all times, a 3.5-metre passage will remain open to cars. Rue de Merl has been reopened to two-way traffic. However, Boulevard Marcel Cahen remains a one-way street until May.

Vehicular access to private property will be maintained as long as physically possible. A diversion for cyclists will be put in place by the Service Circulation. Pedestrian access and access for emergency services will be guaranteed throughout the duration of the works.

For businesses and deliveries:

The City will try to ensure access for deliveries to local businesses throughout the duration of the works.

For public transport users:

Line 15 is now serving all stops once again.

Progress to date

Project update:

Construction will begin on 22 May 2018.

How long will the work take?

Planned completion: end of 2019

What work has already been completed?

A large portion of the work has been completed. The section between the roundabout and Rue Charles Martel has been completed, as has all the sewer work and work for the construction of the medium- and high-voltage multi-cable conduit.

What remains to be done?

On Boulevard Marcel Cahen, the work for the dry utility networks in the pavement. On the section between the roundabout and Rue de la Barrière, the water mains and dry utility networks still remain to be laid. This will be followed by the repair and reconstruction of traffic islands and the final repair of the affected roadways.
