Junction 9 of the M74 is an unusual junction comprising a single, long and sinuous, southbound exit slip road.
It arose from the first southward extension of the M74 in 1986 (see M74 and A74(M) History). This extension was partly an on-line widening of the A74 Blackwood bypass, originally opened in 1963. Where the new motorway line diverged from that of the older bypass, a section of former southbound carriageway survived to form the slip road.
At the divergence the slip road is carried over the B7086 on the surviving eastern half of a 1963 bridge. The western half was demolished to make space for the eastern half of a new bridge carrying the new main carriageways.
The slip road passes under Vere Road by a bridge built to accommodate the original dual carriageway.
At the south end of the slip road it is easy to see that the southward B7078 continues the curve of the slip road, as both were once part of the A74 mainline.
