Maintenance works on the motorway bridge in Thionville are nearing completion, and the speed limit has been raised back to 90 km/h. For several months, major roadworks on the Viaduc de Beauregard – the bridge's official name – had required a reduction in the speed limit on the A31 from 90 km/h to 70 km/h.
Work began at the site in May 2024, with the speed limit subsequently lowered from 90 to 70 km/h in May 2025. The fixed speed cameras on the bridge were also adjusted accordingly. Some 13 months later, the renovation is now almost finished, and the temporary restrictions have been lifted.
The bridge is used daily by some 80,000 vehicles, including many cross-border commuters travelling to Luxembourg for work, as well as Luxembourg residents heading to Metz for shopping. According to information obtained by our colleagues at RTL Infos, the speed limit for cars will remain at 90 km/h, while lorries will be restricted to 80 km/h.
The 70 km/h limit had been introduced as a safety measure, partly to avoid a full closure of this vital crossing. Extensive maintenance was required on the bridge, which was inaugurated in 1972, as decades of steadily increasing traffic had taken their toll on the structure.
While some minor works are still outstanding, those in charge of the project have expressed confidence that, once completed, the bridge will remain in good condition "for the next 100 years." The renovation has cost €13 million, with the French region of Grand Est covering the majority of the expense.
