A pillar-supported wooden bridge was built over the Moesa during the Middle Ages. The bridge maintenance was paid for by the village of the County of Bellinzona, which included Arbedo. The bridge was in a strategic position and in 1495 it was destroyed to slow the Swiss Confederation army. The army then turned and marched in the direction of Lombardy. Also important for trader traffic the stone bridge over the stream Traversagna, which was built in 1485. In the southern foreland, various canals were built which supplied water and power to mills and sawmills that were used throughout the region.
