The Worcester and Birmingham Canal was authorised by the
Worcester and Birmingham Canal Act 1791 (
31 Geo. 3. c. 59), after overcoming opposition by the
Staffordshire and Worcestershire Canal and the
Birmingham Canal Company. The first saw the new route as direct competition, while the second would not allow a junction between the two canals. The canal was built southwards from Birmingham, where there was a gap between the canal and the Birmingham system. Shortly after passing through King's Norton, a ridge of hills was pierced by the Wast Hill Tunnel. Construction of it began in 1794, and by 1807, boats could reach Tardebigge. There was then a period of no activity, but the canal was finally completed to Diglis Basin and the
River Severn in 1815. An agreement enabled a stop lock to be built to connect the canal to the Birmingham Canals in the same year. The Stratford-upon-Avon Canal was authorised in 1793, to ensure that the prosperity being generated by new canal routes would not bypass Stratford. Construction began at Kings Norton Junction, less than from Selly Oak Junction, where the Worcester and Birmingham met with the
Dudley Canal No. 2 line which passed through the
Lapal Tunnel. This route would give easy access to the Dudley coalfields. After the first three years, progress was slow due to a lack of capital, and it was not until the canal reached
Kingswood Junction at Lapworth in 1803, where there was a link to the Warwick and Birmingham Canal (later part of the
Grand Union Canal), that large volumes of traffic used the canal and Kings Norton Junction. The final section from Lapworth to Stratford was built between 1812 and 1815. Although the southern section of the Stratford-upon-Avon Canal was closed, the northern section did not officially do so, although there was little traffic after 1939, and Lifford Bridge, shortly after the stop lock, could no longer be swung after 1942, when the
Great Western Railway repaired it in a way which prevented its movement. It was the scene of one of the first campaigns by the fledgling
Inland Waterways Association, when
Tom Rolt announced in 1947 that he intended to navigate through the junction and along the canal. The Railway company had to jack the bridge up, to allow his boat to pass, and the event was widely reported in newspapers, gaining useful publicity. ==Location==
