Switch Island
Switch Island is a road junction near Aintree in Merseyside, United Kingdom. The juction is at the western terminus of both the M57 and M58 motorways, which converge on the A59 trunk road, the north-south route from Liverpool. The junction is also the terminus of the A5036, a road which serves the Port of Liverpool. Original plans for the two motorways involved them mergeing at this junction and continuing west, while the A59 continued uninterupted under or over the roundabout, with slip roads to and from the junction. These plans were never completed and instead all four busy roads converge at the same level on the single roundabout, made more complicated as the rounabout is currently cut in two by the dual carriageway, which is currently on the same level. To complicate matters further the through route of the dual carriageway is not the A59 south to the A59 north, but from th A5036 south to the A59 north. Effectively, the two motorways and the port road all feed onto the A59 through route at an incomplete roundabout.
The junction carries 80,000 vehiecles per day, and improvements are a priority for England's Highways Agency.
