Closure of the Sentiero dei Principi in Avigliana for Smat works
News of
The Sentiero dei Principi is the hiking trail that climbs from the Mortera hamlet, in the municipality of Avigliana, towards Mount Pirchiriano, linking the hamlet to the Sacra di San Michele. From early November 2026 the trail closes entirely to vehicle, pedestrian and bicycle traffic for about four months, owing to works completing the sewer network in the upper part of the settlement [1].
The works and the funding
The project, worth a total of 266,000 euros, is funded and carried out by Smat, using savings from the sewer works completed the previous winter on via Tresserve. The remaining savings will be used to rebuild the water mains under the Ponte Dora, which suffers from leaks [1]. The project completes the sewer network already begun in the lower part of the settlement during the previous town council term [1].
The closure and its reasons
The plan of works was presented to residents on Saturday 24 October 2026 by Andrea Remoto, the councillor for public works and civil protection, at a public meeting [1]. The narrow shape of the trail and the manoeuvres of construction vehicles require a total halt to traffic until the works are completed, consequently cutting off access to the Sacra di San Michele via this trail for safety reasons [1]. After the pipes are laid and water-related issues on the roadway are resolved, the road surface is due to be resurfaced [1]. Details of the traffic measures are available on the website of the Municipality of Avigliana [1].
