Major Road Network
The Major Road Network is a classification of local authority roads in England. It incorporates the National Highways-controlled Strategic Road Network 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.
2016 Rees Jeffreys Road Fund report
The creation of the Major Road Network was proposed in the October 2016 Rees Jeffreys Road Fund report A Major Road Network for England written by David Quarmby and Phil Carey. The authors stated that the existing Highways England Strategic Road Network, which accounts for 2 per cent of England's roads but 33 per cent of its traffic did not sufficiently safeguard the economically-critical parts of the road network. The remaining 98 per cent of the network is currently under the control of 153 separate local authorities. Quarmby and Carey proposed a new classification of roads combining the SRN with of the most important local authority A roads. This expanded network would account for 43 per cent of the nation's traffic and 4 per cent of its road length.Quarmby and Carey proposed that A roads with average daily traffic flows in excess of 20,000 vehicles be included into the MRN along with roads with average daily traffic flows in excess of 10,000 where more than 5 per cent of traffic was heavy goods vehicles or more than 15 per cent were light goods vehicles. Additional roads were added to link all towns with a population in excess of 50,000 persons to the network, remove isolated sections of road and reflect predicted growth to 2040.
The MRN would be separated into four tiers:
- Tier 1 – limited-access roads devoted to movement between major urban areas and subject to the highest speeds
- Tier 1A – limited-access roads in urban areas with heavier traffic flows, more frequent junctions and require more oversight by a regional authority or city
- Tier 2 – multiple-access roads, usually rural A roads which link secondary urban areas but may have frontages and local access uses
- Tier 3 – multiple-access major roads in urban areas, often with a mix of user types and conflicting movements
