Pont Seibert, Steel bridge between Meudon and Boulogne-Billancourt, France

Pont Seibert is the bridge linking Seguin Island to Meudon on the left bank of the Seine. The old span was a truss-beam bridge that continued as the Pont Daydé toward the right bank. A new steel bridge replaced it, set in place in November 2021, with a single broad flat arch and vertical hangers above the deck.

The first bridge was built in 1931 by the German firm Seibert. It was taken out of service in 1992 after the Renault factory closed, then reopened to pedestrians and cyclists in May 2011 during the redevelopment of Seguin Island. Closed again in 2017, it was dismantled in 2019 because its structure was judged too deteriorated. A replacement was installed in November 2021.

The bridge owes its name to the German firm Seibert, which built the 1931 span; the replacement installed in November 2021 keeps that name. It is meant to carry bus line 42, linking the Brimborion T2 tram stop in Meudon with place Marcel-Sembat in Boulogne-Billancourt, with pedestrian opening announced for 15 April 2026.

The new bridge was installed in November 2021; pedestrian access is planned for 15 April 2026, with bus line 42 following in October 2026. It will link the Brimborion T2 tram stop in Meudon to place Marcel-Sembat in Boulogne-Billancourt. Until then, the crossing is not open, so plan another route between the island and the left bank.

The 1931 bridge was built by the German firm Seibert, which gave the crossing its name. It was dismantled in 2019, and its replacement was lifted into place in November 2021. The new span is meant to carry bus line 42 between the Brimborion T2 stop in Meudon and place Marcel-Sembat in Boulogne-Billancourt.
