Passerelle Saint Laurent, Pedestrian suspension bridge in Grenoble, France

The Passerelle Saint-Laurent is a pedestrian suspension bridge over the Isère in Grenoble, linking the historic centre on the left bank to Place de la Cymaise in the Saint-Laurent district. Its flat walkway has dark metal railings and is carried by diagonal black cables running from a massive white stone pier on the left bank down to a stone abutment on the right. A lower rectangular metal platform, also railed, hangs beneath the deck.

A ford at the Rabot cliff narrowing was crossed by a temporary bridge built by Lucius Munatius Plancus on 12 May 43 BC. Around 1095 Bishop Saint Hugh had the first stone bridge built; it was carried away by the September 1219 flood, and a square toll tower with a Notre-Dame chapel rose from 1381 to 1423. After the 1651 collapse of two arches and the tower, a wooden bridge followed, replaced in 1837 by an iron-wire suspension bridge with a timber deck.

The bridge links two contrasting neighborhoods and serves as a daily passage for residents and visitors moving between the city center and the Saint-Laurent district. It functions as an important crossing point in the rhythm of urban life.

The footway is accessible year-round and provides a level, safe crossing without steep slopes or obstacles. The nearest tram lines are A and B, with stops at Hubert Dubedout Maison du Tourisme station.

The chapel on the bridge was moved under the vault of the square tower in 1443, and in 1492 the city arms were placed "ante capellam beate Mariae super pontem". The tower, built 1381-1423 with demolition materials, also held an astronomical clock and two jacquemarts; Lesdiguières' artillery destroyed the figures during the siege that ended in 1590.
