Halfway River Bridge

Mile 37.17 on the Halifax Subdivision

Located just east of Hantsport, the bridge crossed the Halfway River (so named because in early times it marked the halfway point between Grand Pre and Windsor.)[1]

The bridge began in 1869 as a wooden truss bridge with a pile trestle approach. The wooden truss crossing the river was 150 feet long, while the trestle had 32 spans of pile trestles, each 20 feet long. A report by engineer Alexander MacNab in 1873 noted that the main span was weak and needed a pier in the middle and that many of the pile trestles were being replaced by trestle bents.[2]

The wooden bridge was replaced by a causeway with an aboiteau in 1879.[3]

By 1969, the bridge consisted of a 40-foot-long pile trestle over a spillway on the east side of a causeway at the Halfway River over an aboiteau with three 60-inch corrugated metal pipes.[4]

DAR crews had to fill in a major washout at the Halfway River bridge in August 1971.[5]

The railway ceased to be used in 2011. The causeway slowly began to erode and the aboiteau gates ceased functioning. Erosion increased dramatically in September 2017 and a large washout occurred in the causeway, leaving the rails hanging in mid-air and exposing the pile trestle work of older versions of the bridge.[6] The Windsor and Hantsport Railway removed the hanging rails in 2018 but the washout grew leading to extensive tidal flooding of the formerly protected Halfway River Valley which raised fears about erosion and flooding of roads and power lines. The flooding has led to a dispute between the Province of Nova Scotia and the Windsor and Hantsport Railway over who owns the aboiteau and who bears the responsibility for the washout.[7]
