Limestone Bridge, 3.8 meters. Built between 1865 and 1870, the Limestone Bridge on Hays Road in the Totara Valley is one of several stone arch bridges built in South Canterbury during the 19th century. It stands as a lasting testament to early engineering and a high level of craftsmanship. Constructed by the Levels Road Board and still in use today, the Limestone Bridge is one of the few intact limestone arch bridges in the borough and possesses historical, archaeological, aesthetic, and architectural value. Between 1865 and the 1880s, several stone bridges and culverts were built in South Canterbury. Most were small, single-span structures constructed from local limestone or bluestone (basalt). Early newspaper accounts of Levels Road Board meetings included references to a 'Manuka Bridge' at Totara Flat. In 1874, Mr. W. Williamson, the board's engineer, suggested that it might be better to forgo further bustling.
