Many modern European roads were originally constructed as toll roads in order to bring in the costs of construction. Tolls on roads and bridges were very common in England in the 12th century and in the 15th century, schemes for improving particular roads or rivers were granted by acts of Parliament that authorised justices to levy rates for the repair of certain roads. In 1706, a new concept of road tolls was introduced in England: the turnpike trusts. The turnpike trusts were authorised to erect gates, collect tolls, appoint surveyors and collectors, demand statute labour or its monetary equivalent, mortgage the tolls, elect new trustees, and undertake work necessary for repairing the roads. By 1750, most of the main roads between London and the provincial centres and some inter-provincial routes had been turnpiked. By the mid-1830s, over 1000 turnpike trusts controlled 35'000 km of main roads and disposed about 1.5 million pounds of toll receipts each year. However, the rise of railway transport largely halted the road improving schemes of the turnpike trusts, and from the 1870s, the Parliament stopped renewing the acts and roads began to revert to local authorities; toll roads passed out of fashion until the later 19th century.
