The A4123, also known as the Birmingham New Road or Wolverhampton New Road, is a major road in the West Midlands linking Wolverhampton with Birmingham. It was one of the first major new roads constructed for use by motor traffic, and was designed as an unemployment relief project. It runs roughly northwest to southeast from the Wolverhampton Ring Road to Harborne, west Birmingham.
Construction of the road began on 4 February 1924, and was built in individual sections., and provided jobs for at least 470 unemployed workers in surrounding areas including Birmingham, Wolverhampton, Dudley, West Bromwich, Smethwick and Oldbury. It was opened by the then Prince Of Wales (later Edward VIII of the United Kingdom) on 2 November 1927.
