Originally constructed as a Directional T interchange, the Bridgewater Interchange was converted to a signalised, grade-separated dumbbell junction when the Mersey Gateway Bridge was constructed during the mid-2010s. The Central Expressway was effectively extended over this junction as a flyover, linking the bridge's approach viaduct, and effectively segregating the A533. Northern sliproads were added leading to the bridge, and the Southern ones were reused, so as to fully link the A558 through the junction, and underneath the A533. This junction also acts as the final exit before having to pay the bridge tolls.
