Halfway River Bridge
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) where it meets the larger Avon River.[1] The Halfway River is small, but it has a deep tidal estuary surrounded by wide tidal marshes where it is crossed by the DAR. This crossing required regular upgrades and repair throughout the history of the DAR.
The river was first bridged by the DAR in 1869 with a 1,800 foot trestle and a covered wooden truss bridge.[2] By 1873, an engineer's report indicated that the trestle was 640 feet long (32 trestle spans, each each 20 feet long) and the bridge was a 150-foot long wooden truss bridge. The report by engineer Alexander MacNab noted that the main span was weak and needed a pier in the middle and that many of the pile trestles were gradually being replaced by trestle bents.[3] The wooden bridge was replaced by a causeway with an aboiteau in 1879.[4] The aboiteau as rebuilt in 1914-1915.[5]
By 1969, most of the trestle approach had been filled and converted to an embankment leaving a 40-foot-long pile trestle over a spillway on the east side of a causeway crossing the Halfway River over an aboiteau with three 60-inch corrugated metal pipes.[6] DAR crews had to fill in a major washout at the Halfway River bridge in August 1971.[7]
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.[8] The Windsor and Hantsport Railway put up barricades and removed the hanging rails on February 7, 2018,[9] 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.[10] After the site the site was documented by arachaeologists, the province rebuilt the aboiteau in the fall of 2019 and is suing the Windsor and Hantsport Railway for the cost.[11]
