Overnight closures of viale Sauro and via Ricasoli required diversions on several Siena public transport routes. On 10 April, the council published a notice covering 13–23 April, from 8pm until 6am the following morning. The changes affected urban and interurban services, with alternative routes through via Veneto, via Montesanto and via Cesare Battisti varying by destination. The notice also listed temporarily suspended stops. This report reconstructs a time-limited measure whose dates have passed; it is therefore not presented as an operational update on current routes.
