A campaign to save an historic bridge over the Hudson River in the USA will come to fruition next year when the former railway bridge is planned to reopen as a dramatic river crossing for cyclists and pedestrians. Eric DeLony reports on the work so far, and what has still to be achieved

Refurbishment of a tourist railway in the Kalavrita valley has required engineers in Greece to come up with some imaginative solutions. Narrow and restricted access, steep slopes and historic structures made the contract, to replace bridge bearings and improve the seismic response of the structures on the line, particularly challenging.

John Mitchell is a contented man. Bridge master of Clifton Suspension Bridge, he is in reflective mood in the bicentennial year of its designer's birth. Although Brunel never saw this elegant marriage of function and form completed, his fondness for the project was clear, describing as 'my first child, my darling'. Mitchell shares this passion for the structure, as have other engineers who have been fortunate enough to look after what is one of the great icons of England's south west, and one of Brunel's more enduring legacies.

In recent years in St Petersburg, a lot of work has been going on to repair,

The cantilever is one of the world's earliest bridge forms originating in China, Tibet and Japan. Shogun's Bridge built in the 4th century AD still spans 26m over the Daiya-gawa River in Nikko, Japan. In the mid-nineteenth century, this structural bridge form was reintroduced and used extensively. But today, two of the world's oldest cantilevers are struggling to survive in the USA.

Two bridge deck overlay replacement projects that have been under way in the Netherlands this summer represent the culmination of a major research effort into solving problems with fatigue damage to steel deck bridges.
