RESTI DEL PONTE ROMANO DETTO "PONTE VECCHIO"

The Dora Baltea once split into two branches here, the main channel cutting the plain west of Ivrea. On this river, at the narrowest point on the city’s western edge, where the decumanus maximus met the road to Augusta Taurinorum, the Romans built a stone bridge. Now called the Ponte Vecchio, it still carries traffic alongside its modern neighbour a hundred metres downstream.

Though much altered by centuries of destruction and rebuilding, the original Roman structure likely spanned the gorge with two asymmetrical arches. The larger, a full round arch of 14 metres, crossed the main current where water pressure was greatest, between the right bank and a rocky spur. The smaller, a 7.5-metre arch, spanned the gentler flow between the spur and the left bank. Both converged on a single pier, founded directly on living rock, its jagged surface trimmed to receive the masonry.
