With the advent of artificial canals, most of them were constructed with towpaths suitable for horses.[2] Many rivers were improved by artificial cuts, and this often gave an opportunity to construct a towing path at the same time. Even so, the River Don Navigation was improved from Tinsley to Rotherham in 1751, but the horse towing path was not completed on this section until 1822.[3] On the River Avon between Stratford-upon-Avon and Tewkesbury, a towpath was never provided, and bow-hauling continued until the 1860s, when steam tugs were introduced.[4]
