An historic steel truss bridge in New York, USA, has been raised by 1m to improve resilience against flooding and ice jams.

Carpenter’s Flats Bridge over the Ausable River now rests on concrete caps that were poured on top of the existing substructure. The project, which was declared complete on Tuesday, also included work to improve the approaches and to bring guide rails up to modern standards.

The bridge was constructed in 1941 and rehabilitated in 1994. It is 78m long and can be found on the National Register of Historic Places. In recent years it has been repeatedly closed following ice impacts.

Funding for the project came from the state, and the Federal Emergency Management Agency (FEMA).
