Plans were announced in February 2016 which proposed a new £200m road could be built through Rimrose Valley to link directly into the A5758 Broom's Cross Road in an effort to reduce the heavy congestion on the A5036 Dunnings Bridge Road; Sefton Council rejected the proposal in March 2017, citing the desire to instead build a tunnel to overcome the congestion concerns. In December 2017, Highways England attempted to defend their position that a bypass road is the preferred option to provide a direct link between the Port of Liverpool and Switch Island junction, citing considerable cost and disruption if a tunnel, estimated to cost six times as much, were to be constructed.
