|Junctions related to the A577|
It opened on 25 March 1968 following completion of the western section of the A506 Skelmersdale Regional Road and the first part of Stannanought Road which linked to Holland Moor and the existing A577 from Wigan to Skelmersdale. Both roads were opened as single carriageway roads due to restriction of Ministry grants.
The eastern dual carriageway extension and connection to M6 was not long coming and this opened on 1 October 1970.
It was then upgraded to motorway in 1977. At this time the eastbound to northbound sliproad was closed, meaning to travel north requires a full circuit of the junction. Therefore traffic for Skelmersdale heading from Liverpool tends to leave a junction earlier.
The original intention was to rebuild this sliproad along with the addition of a westbound to northbound loop and the southward continuation of Stannanought Road. None of this ever happened but evidence of the loop exists by the skew of the westbound M58 bridge over Stannanought Road.
