M6 Junction 21
Junction 21 was one of the earlier junctions on the M6 being opened in July 1963 for 4 months it was the southern end of this section of the M6 which had opened southwards from the original Preston Bypass. The junction being the junction for Warrington and Irlam on the A57 the original Trunk Road link between Liverpool, Manchester and Sheffield. The junction is similar to junction 31 at Preston the very first motorway junction in the country being a double roundabout, except this time the road is carried over the M6. The junction is shown below:-
The motorway was opened further south in November 1963, going from this junction straight onto the Thelwall Viaduct. The junction contained some very tight turns as shown below:-
During the 1990's a forth lane was added to the M6 as well as the A57 being dualed between the two roundabouts resulting in the junction now being as shown below:-
