size of the park, the area has been divided into five colour-coded zones that allow people to narrow down their location if they need to contact the emergency services. The north–south walking distance is approximately , with a grade of moderate and an estimated walking time of 90 minutes. Highway proposals Early considerations for a road through the valley were in 1990, when it was reported that plans were being drawn up for a dual carriageway through the valley, despite having previously been earmarked for wildlife. In March 1993, the Liverpool Echo reported that residents were suggesting a road be built with restrictions on commercial vehicles and the council were understood to be considering it. In January 1994, it was reported that a 70mph dual carriageway through the valley to ease traffic was a favoured option, which was anticipated to connect with another road that had been planned, the 'Blue Route'. Then-highways chief for Sefton, Geoff Cowie, believed a road would give good value for money and hoped for a quick decision. In 2013, under the leadership of Peter Dowd, Sefton Council placed members of council, as well as its Chief Executive, to the Port Access Steering Group to work with Highways England and Peel Ports (as well as other agencies) to establish "a permanent highways solution" due to the expansion of the port. Sefton Council was chairing the Port Access Steering Group on behalf of the Liverpool City Region (LCR). From this, in the same year, Sefton Council commissioned the Atkins Group to conduct a feasibility study for the road solution. The report/study was completed in February 2014. In November 2014, Atkins made a presentation to the LCR Port Access Steering Group, three of whom (including the chair) were from Sefton Council. In their presentation, Atkins summarised the latest thinking in relation to the Online Option and the Offline Option, as well as considering tunnel options which were deemed to be "cost-prohibitive". The Online and Offline options would later be referred to as Option A and Option B in Highways England's public consultation of 2017. Following the presentation, the Steering Group gave Highways England the task of deciding on Option A or B. The announcement came two years after the completion of the feasibility study in February 2014. In 2003 a similar study had been conducted, commissioned by Sefton Council, and the preferred option then was Rimrose Valley. Plans
