Sandside railway station, on the Hincaster Branch of the Furness Railway, was built in 1876 by Lancaster architects Paley and Austin. The line closed to passengers in 1942 and the station has been demolished.
Until the building of the Arnside viaduct in 1857, Milnthorpe (upstream of Sandside) was a substantial port, handling cargoes including coal and guano. Its customs house was at Sandside, still existing as Crown Cottage with a datestone of 1728. Builders' merchants and other commercial operations occupy sites along the riverside which were previously used by the merchants of the port.{{cite news|last1=Bingham|first1=Roger|title=Milnthorpe once had a 'thriving port'|url=http://www.thewestmorlandgazette.co.uk/nostalgia/8345078.Milnthorpe_once_had_a__thriving_port_/|accessdate=2 November 2014|work=Westmorland Gazette|date=20 August 2010}}
