€52M Road Project Boosts Saint-Tropez Property Values by 2027

The Saint-Tropez coastal road upgrade reached its first major milestone on 8 July when crews finished the new roundabout at the junction of Boulevard de la Mer and Route de la Foux.

Buyers have already moved on the news. Local estate agents recorded 14 signed contracts for apartments within 400 metres of the route in the past six weeks, compared with seven in the same period last year.

The work matters now because the existing single-lane road funnels all summer traffic through the centre of town. Once the new two-lane section opens, journey times from the A570 motorway to the Vieux Port will drop by roughly 18 minutes on peak days.

Street-level changes in two neighbourhoods

Properties along Rue du Portalet and the upper end of Rue Gambetta sit closest to the new carriageway. Both streets already back onto the Place des Lices market square, where weekly produce stalls draw visitors who will now reach the area faster. The local planning office has also approved three small infill sites on Rue du Portalet for six new apartments each, with building permits issued in May.

Further east, the Résidence du Parc gated development on Avenue Paul Signac has seen its resale listings cut from nine units in January to three today. Agents attribute the shift to improved access once the coastal road links directly to the existing cycle path that runs past La Citadelle.

Price data and buyer patterns

Figures from the Saint-Tropez notaire’s office show average sale prices for apartments in the affected postcodes rose from €19,800 per square metre in the second quarter of 2025 to €22,450 in the second quarter of 2026. The biggest gains appeared in units with sea views, up 17 percent year on year. Comparable sales in the western La Ponche quarter, untouched by the road, increased only 4 percent over the same period.

Developers expect the final asphalt layer to be laid by March 2027. Anyone considering a purchase should check the latest traffic-impact studies published by the Var department before committing, and confirm whether their chosen property falls inside the new 300-metre noise-protection zone.
