VINCI Construction continued replenishing its order book in these geographies despite a sometimes challenging backdrop, in particular due to the economic impact of unrest in Mayotte, New Caledonia, and the West Indies in 2024. Business volumes remained stable, with revenue standing at €0.75 billion. Business is holding up in Guadeloupe and Martinique thanks in particular to projects in construction and water supply networks. In French Guiana, business was buoyed by social housing projects, orders from the Guiana Space Centre and a number of other large projects including the courthouse in Cayenne. At Le Larivot, also in French Guiana, VINCI Construction is building a 120 MW bioenergy power plant which will supply the city of Cayenne (population approximately 65,000) with electricity. Civil engineering work was completed in 2025. On Reunion Island, prospects in the building sector are encouraging, both in renovation and new build. Teams are currently working on the Espace Bertel, a large-scale property development (30,000 sq. meters) combining shops and offices in Saint-Denis. Mayotte is gradually recovering from Cyclone Chido, which wreaked havoc on the island in late 2024; reconstruction operations have begun and should reach their peak in 2026. VINCI Construction is also carrying out the second phase of the Caribus program, Mayotte’s first bus rapid transit network, designed to relieve traffic congestion and offer accessible and affordable transport options. New Caledonia has yet to recover from the aftermath of the 2024 crisis. Conversely, business continues to grow in French Polynesia.
Business volumes remained stable in 2025. In roadworks, VINCI Construction’s main area of activity in the country, the most significant projects were the widening of the A81 motorway near Stuttgart, renovation of the B3 federal road near Hanover and upgrading of the A59 motorway near Duisburg. Other projects included the renovation of a section of the A6 near Saarbrücken (where the asphalt plant used biofuel, eliminating approximately 200 tonnes of CO2 emissions) and of the A31 motorway in North Rhine-Westphalia, extensive street upgrades in Hamburg, and improvement work on Blumberger Damm, a thoroughfare in Berlin. Also in Berlin, the Via Structure subsidiary is building the new Elsen bridge, replacing one of the city’s busiest. The project reached a major milestone when the 400-tonne central section of the new bridge superstructure was successfully installed in October 2025. Other important projects included the replacement of the Steinhavel lock in Brandenburg, the general overhaul of the Riedbahn line operated by Deutsche Bahn between Frankfurt and Mannheim, and the construction of several electricity substations in cooperation with a number of VINCI Energies business units. One such project under way relates to the extension of a local wind farm located near Ahaus (North Rhine-Westphalia).
In roadworks, VINCI Construction’s subsidiaries completed motorway sections spanning more than 40 km in the Czech Republic and 18.5 km in Slovakia, contributing to the improvement of transport infrastructure in these two countries. In the Czech Republic, work continues on three sections of the D6 and two sections of the D35. Construction of the new 12.6 km section of the ring road east of Prague also progressed, while work started on the country’s largest arch bridge near the town of Plasy.
In rail works, operations to modernise the junction began at Central Europe’s largest freight station in Česká Třebová (Bohemia). In Prague, regional subsidiaries were involved in laying new tram tracks on Wenceslas Square in the city’s historic centre. In Košice, Slovakia, reconstruction began on the city’s tram lines.
In the building sector, a new modern primary school with a capacity of up to 540 pupils was completed in Bašť, near Prague. In Brno, the Czech Republic’s second largest city, work began on expanding the wastewater treatment plant and the municipal water management network.
In water works, regional subsidiaries took part in the extension of the Klecany hydroelectric power station.
