This junction was the location where the Wishaw and Coltness Railway (this portion opened around 1842) was met by the Caledonian Railway in 1848. The Caledonian used the W&C as part of its approach to Glasgow and to the north.
Going east on the W&C the line dropped to a single track at the foot of the Morningside Incline (at Morningside Incline Signal Box). The line continued to the Coltness Iron Works and beyond.
There were sidings at the junction which were expanded to include a yard on the north side, west of the junction and approached from the east, and another to the south, east of the junction and approached from the west. A signal box was built north of the junction.
In 1880 the Wishaw Deviation (Caledonian Railway) opened connecting the main line south at Law Junction to Carfin Junction, this new line flying over the top of the W&C just east of the junction.
The signal box closed in 1973, replaced by the Motherwell Signalling Centre. The junction became a single lead with a loop at the start of the W&C line.
After closure of the line to Kingshill Colliery No 1 in 1974 the W&C route was reduced to a short branch to the Costain concrete works.
The loop by the junction was taken out in advance of the deviation line's deteriorating bridge over the older line was replaced.
It served a short lived coal loading pad near Stirling Road Junction (Watsonhead Loading Pad) in the 2000s. The junction was taken out around 2015.
