Anne-de-Bretagne bridge: widened for trams, bikes and walkers
The new part of the bridge between the quai de la Fosse and the Île de Nantes opened to pedestrians and cyclists on 23 October 2026, with a timber-decked promenade jutting out over the Loire as a viewpoint and a planted linear garden; cars follow south to north by the end of November. Works now move to the original bridge, to be lowered and strengthened to carry a two-way cycle track, planted walkways and the new tram track, with full opening around the end of 2027, when it will be the widest bridge in Europe.

Metropolitan express rail service (SERM) Nantes Saint-Nazaire
Labelled by the State in June 2024, the "metropolitan RER" promises trains every 30 minutes at peak times by 2030-2035, backed by express coaches, car-pool lanes and cycle routes. On 2 October 2026 the metropolitan council approved two rail studies under the 2021-2027 State-Region plan: modernising signalling around Nantes (€45.56m, €2.9m from the Métropole) and a more frequent Nantes-Pornic and Saint-Gilles-Croix-de-Vie line (€7.5m of studies, works mid-2031 to end 2033).
Budget 45,56 M€ (signalisation) ; 7,5 M€ (études Nantes-Pornic) Funded by Contrat de plan État-Région 2021-2027; Nantes Métropole (2,9 M€ and 750 000 €) MobilityStatus checked 23 October 2026 · Source

Mazaire biomass heating network, La Chapelle-sur-Erdre
A wood-chip boiler house with 500 m of underground pipes, under construction until January 2027, will heat 10 public buildings (a secondary school, a primary school, a nursery, a gym) in place of ageing gas boilers, cutting their CO2 emissions by 70%, or 170 tonnes a year; it is one of 12 new networks in the Métropole's heat network plan, and a residents' monitoring committee follows the project.
