Infrastructure and roadwork projects are underway across various regions in France and its territories. In the Grand Est region of France, a €70 million project to expand the RN4 highway near Saint-Georges is in the earthworks phase, with completion expected by 2030.

In Réunion, multiple maintenance and reconstruction efforts are impacting local transit. These include safety barrier repairs on the RN1 near Étang Salé, the reconstruction of the Ravine Harmonie crossing on the RN2002 in St Benoit, and cliff stabilization work on the RN5 Route de Cilaos. Additionally, nighttime closures are scheduled for the Boulevard Nehru structure in St Denis.

In mainland France, repairs on the Passoir bridge in La Boissière-École are set to begin in early October, requiring detours and modified public transport access. This period also includes scheduled archaeological excavations near the D71 as part of urban development.
