M55 motorway meet junction 4, where the motorway ends and becomes the A5230. The western part of the M55, and the first few hundred metres of the A5230, occupy the route of the old Blackpool Branch railway line. The first motorway constructed in Great Britain was the M6 Preston Bypass, opened in 1958. This ran from the current M6 junction 29 to the M55 junction 1. It was built as a two-lane route. In 1965 the M6 was extended north from what is the current day junction 32 to meet the Lancaster Bypass, and the M6 junction was rebuilt to its current
Heysham to M6 Link Road Heysham to M6 Link Road The Heysham to M6 Link Road, known as the Bay Gateway, is a dual carriageway link road between the Heysham and Morecambe peninsula to Junction 34 of the M6 motorway in Lancashire, England. It was opened on 31 October 2016. In the process, Junction 34 was remodelled. The concept was published in the document "Road Plan for Lancashire", in 1948. The idea was revived in 1962 in the Lancashire Development Plan. The first phase, known as the Lancaster and Morecambe bypass, opened in 1994, leaving the Lune crossing and the motorway link unbuilt.
