San Casciano Tunnel – San Casciano Val di Pesa (FI)

Also for the #greenlight project by ANAS Arianna is located in Tuscany in the province of Florence in San Casciano Val di Pesa in the San Casciano tunnel on the Florence – Siena RA3 motorway connection. This gallery is part of the #greenlight Toscana lot awarded by our partner Bouygues Italia.

The tunnel redevelopment project had to include a replacement of the existing SBP and SAP light fixtures, maintaining the same power and the same number of floodlights.

The new Arianna lighting guarantees high uniformity, without shadowy areas, and a very low level of glare along the entire tunnel. Furthermore, thanks to the innovative characteristics of the Arianna lighting fixtures, the reinforcement lighting combines high performance with zero glare for maximum safety.

The goal of making the tunnel much safer and more comfortable has undoubtedly been achieved. The surveys carried out after installation confirm that the lighting project was carried out to perfection and that all the client’s requests were respected.


The San Casciano tunnel is a one-way tunnel with two traffic lanes, consisting of two pipe structures, one towards Siena and the other towards Florence, both approximately 400 m long.

The Petrarca Tunnel was installed in the CRI 80, 4000 K configuration with radio wave remote control for both the permanent and reinforcement lighting.

In all, 190 Petrarca Tunnels were installed for the two pipe structures; 55 as permanent features and 135 for reinforcement; with a total power of approximately 35 kW.
