XCarb® in iconic bridge solution

Scroll down to read the article

ArcelorMittal is partnering with long-standing customer, construction firm, GAGNE, designer Setec, and the Department of Isère, in the French Alps, to build an iconic new bridge over the Isère river at Brignoud, north of Grenoble.

The previous bridge was irreparably damaged by fire in early 2022. The Department of Isère quickly initiated a reconstruction programme for this important crossing, with a target date for completion before the end of 2026. Specifications included responding to the needs of all users, including road, pedestrian and cyclists, and providing for future levels and types of usage, through incorporating a greater width and number of lanes. The crossing typically handles around 27,000 vehicles a day, is important for local businesses and provides access to busy ski resorts.

The new bridge has an exciting ‘Bow String’ design to reflect the architecture of its predecessor. It will be 23 metres wide, facilitating four lanes of traffic. In addition, the solution goes further by incorporating a second bridge for pedestrians and cyclists.

ArcelorMittal worked closely with customer GAGNE to respond to the tender. It is supplying 150 tonnes of XCarb® recycled and renewably produced heavy plates. The steel is being primarily used in the bridge suspenders.

The new arch bridge will feature a series of steel suspenders manufactured with ArcelorMittal’s XCarb® recycled and renewably produced heavy plates.

A second tender is under way for the 100 tonnes of steel required for the footbridge, and is to be awarded in 2026 for completion in 2027.

Frederic Marechal, Account Manager, ArcelorMittal Europe – Flat Products, added: “The bridge solution for this project is an exciting one, and the Bow String design and specifications are a perfect fit for our steel plate offering. It’s a great chance to demonstrate the benefits of XCarb® and we’re delighted to be working again with GAGNE.”

XCarb® recycled and renewably produced heavy plates have a low carbon footprint of 914 kg CO2e per tonne of steel, achieved through the electric arc furnace (EAF) production route, using minimum 95% high-quality scrap and 100% renewable electricity.

Construction work commenced in April 2025. The road bridge is due for completion and opening to traffic at the end of 2026, and the footbridge for completion by the end of 2027.
