A556 road

The A556 is a road in England which extends from the village of Delamere in Cheshire West and Chester to the Bowdon Interchange in Cheshire East, bordering Greater Manchester. The road contains a mixture of single and dual carriageway sections and forms a large part of the route between Manchester and Chester. It also acts as a major access route to Chester/North Wales to the west and to Manchester to the east for the conurbation of towns and villages around the Dane Valley centering on Winsford and Northwich. The central part, which forms the Northwich Bypass between Davenham and Lostock Gralam, suffers because of the amount of commuter traffic from this area. The part of the route between the M6 motorway Junction 19 and the M56 motorway Junction 7 is a major route into Manchester and has been recently upgraded to a four-lane dual carriageway.

The road is frequently congested, carrying approximately 80,000 vehicles per day in 2020 between the M6 and M56 and 45,000 vehicles per day From the A533 Junction for Winsford and Northwich to the M6. The road has a high accident record; between 1998 and 2005, there were around 200 accidents, resulting in 5 fatalities and 39 people being seriously injured.
