The M60 Motorway is Manchester's Outer Ring Road. It was constructed in stages.
The first section to open was the Stretford and Eccles bypass which was originally numbered M62, later renumbered to M63. This section opened to traffic in October 1960 and was one of the first motorways to open in the UK, indeed the beginning of the foundations to the Barton High Level Bridge in the 1950s was the UK's first construction project involving a motorway, starting even before construction of the M6 Preston Bypass and the M1.
The next major milestone was the completion of the M62 to the North and West of Manchester, opening in 1971.
By 1975, the M63 had been extended to Cheadle, and the M66 had been constructed down to Heaton Park.
In 1982, Stockport was bypassed, and in 1989, a portion of the M66 was constructed, joining Stockport to Denton, leaving a 9.5 mile gap in the M66.
This gap was finally plugged in October 2000 when the ring was completed. The motorway was renumbered as M60 upon completion. The junctions were numbered so that the M62 junctions kept their number. Junction 1 is on the south side of Manchester at Stockport.
