Arco Municipality Explains Traffic Management for Bridge Walkways

The Municipality of Arco has explained the reasons behind the new traffic layout introduced for the bridge walkway construction, saying the restrictions are required by technical constraints and to ensure safety, public transport continuity, school access, and passage for emergency vehicles.

According to Vice Mayor Marco Piantoni, concerns were raised after all traffic leaving Prabi was directed south, but the council said it is currently the only technically viable option. A three-week test with both lanes open showed about one in three vehicles used the route toward the bridge, guiding subsequent decisions. Checks with local police and Trentino Trasporti—including simulations with real vehicles—found that during the main works, the bridge’s west entrance bottleneck prevents longer vehicles from exiting the town center; the limits are therefore not discretionary but linked to the construction geometry. The plan will be implemented in phases: first keeping the turn toward the bridge open to all vehicles, then banning turns for vehicles leaving Prabi and requiring them to go straight, and finally extending the ban to vehicles from via della Cinta, with access for long and bulky vehicles to the bridge allowed only from the east. For public transport, the agreement with Trentino Trasporti sets that, except for Bus & Go, buses will cross the bridge only entering from the east and exiting to the south via via della Cinta, also aligned with morning school access for Prabi’s middle schools. The municipality is also working to improve signage in the construction area to make restrictions clearer for residents, tourists, and through-traffic.
