A47 Road - History

History

The original (1923) route of the A47 was Birmingham to Great Yarmouth, but there were some changes made to its route in the early years. At its eastern end, the A47 originally ran through Filby and Caister, with the Acle Straight bearing the number B1140. The A47 was rerouted along the Acle straight in 1935, with the old route being renumbered as the A1064 (Acle to Caister) and part of the A149 (Caister to Great Yarmouth).

The second change also dates from 1935. The A47 originally ran via Downham Market, not King's Lynn. In 1935, it was rerouted via King's Lynn, replacing part of the A141 (Wisbech to King's Lynn) and part of the A17 (King's Lynn to Swaffham). The old route via Downham Market was renumbered as the A1122 (Outwell to Swaffham) and part of the A1101 (Wisbech to Outwell).

The third change took place some time before 1932. The original route of the A47 between Guyhirn and Wisbech was via Wisbech St Mary, with the direct route being part of the A141. This is because there was no road bridge over the River Nene at Guyhirn, and hence no junction between the A47 and the A141. Some time between 1923 and 1932 a bridge was built, and the A47 and the A141 swapped routes between Guyhirn and Wisbech.

Major improvements were made from the late 1970s until early in the 1990s. The 7 mile (11.3 km) £5 million part-dual-carriageway East Dereham Bypass built on part of the disused railway line was opened in spring 1978 followed by a five mile (8 km) part-dual-carriageway Swaffham Bypass, costing £5 million which was opened in June 1981. Bypasses for Uppingham (£1.4 million) and Blofield (£4 million) were opened in 1982 and 1983 respectively. The southern section of the Great Yarmouth Western Bypass was opened in May 1985 and the northern section in March 1986 at a cost of £19 million followed by improvements to the one mile (1.6 km) Postwick-Blofield section (£1.2 million) which was opened in November 1987. In 1989 Acle Bypass was completed as a cost of £7.1 million and the £1.2 million East Norton Bypass was opened in December 1990. The three mile (4.8 km) £9 million East Dereham-North Tuddenham Improvement opened in August 1992 and the £62 million Norwich southern Bypass in September 1992.

Escalating road protests starting with Twyford Down in 1992 and culminating with the Newbury bypass in 1996 (at which over 1,000 people were arrested) led to over 300 road schemes being cancelled in November 1995 and to the cancellation of further schemes including the Thorney bypass by the new Labour government in 1997.

In 2002 the government announced a new road building programme which included the three mile (4.8 km) dual-carriageway Thorney bypass which opened on 14 December 2005.
