Major Road Network has part(s) of the class A road
The Major Road Network (MRN) is a classification of local authority roads in England.  It incorporates the National Highways-controlled Strategic Road Network (SRN) and the more major local authority controlled  A roads.  This network accounts for around 4 per cent of the nation's road length but 43 per cent of the traffic flows.  It is designed to allow central government funding to be more effectively targeted towards the more economically critical road infrastructure.  The system was proposed by the Rees Jeffreys Road Fund in October 2017 and adopted by the government in its 2017 Transport Investment Strategy.  The MRN scheme was implemented in late 2018 and local authorities were required to submit proposals for £3.5 billion of funding for new schemes to be constructed 2020-25.
