Highbridge grew in importance as a regional market and industrial town during the latter half of the 19th century and the early part of the 20th century. Important employers included the livestock and cheese market, Highbridge Wharf, Buncombe's Steamrollers, and the Somerset & Dorset Joint Railway railway works, which closed in 1930 with the loss of 400 jobs. Heavy industry and transport declined in Highbridge after the Second World War as the Wharf proved too small for the newer generation of ships, with the last cargo of timber arriving in 1948 and the wharf was closed to shipping the following year, and commercial freight moved away from the railways. Since the 1970s close proximity to the M5 motorway has driven a growth in light industry and in the town's commuter population.
