Traffic information

What is the current traffic situation?

For cars and pedestrians:

Most of the work will be carried out inside the large fenced-off areas. Traffic on Rue du Fossé will not be affected. During the work, most parking spaces in the Knuedler car park will remain accessible. In the event of any changes to vehicle access, appropriate signage will be put in place.

For businesses and deliveries:

The City will ensure that deliveries to local merchants can continue uninterrupted throughout the duration of the works. Access to Place Guillaume II by way of Rue du Fossé will be remain open.

The City thanks local residents, businesses and road users for their understanding and apologises in advance for any inconvenience caused.

Progress to date

What work has already been completed?

Most of the horizontal micropiles to support the umbrella arch that will serve as the overhead covering for the car park. Archaeological digs undertaken by the National Centre for Archaeological Research (Centre National de Recherche Archéologique – CNRA). Boring of post holes and erection of metal posts. Demolition and structural works to rebuild the staircase on the north-western side.

What remains to be done?

Complete the jacking and injections to build the umbrella arch. Erect girders to link the umbrella arch and vertical columns. Then the contractor will commence the mass excavation works. Next, they will carry out the underpinning works for the arches and ramps in the existing car park before building the extension in the excavated section. In the last stage of construction, they will renovate and refurbish the existing car park.
