Turnpike trusts were bodies set up by individual acts of Parliament, with powers to collect road tolls for maintaining the principal roads in Britain from the 17th but especially during the 18th and 19th centuries. At the peak, in the 1830s, over 1,000 trusts administered around 30,000 miles (48,000 km) of turnpike road in England and Wales, taking tolls at almost 8,000 toll-gates and side-bars.
