APPENDIX 3- DEVELOPMENT AFFECTING MOTORWAYS AND TRUNK ROADS
     
1. The Secretary of State is the highway authority for the trunk road network (which includes most motorways) in England. The Highway Agency, an executive agency of the DTLR, is responsible for the management and maintenance of the network and delivery of the Secretary of State's programme of trunk road and motorway improvements.
  2. For development which may cause a material increase in traffic on the M6 and/or its junctions, the Highways Agency will require a Transport Assessment and will require the developer to fund any necessary.
  3. Transport Assessments will be required by the Highways Agency for any development where any significant increase in levels of traffic may directly or indirectly affect the national or trunk or motorway system. The Highways Agency should be consulted at an early stage to agree the scope and content of the Transport Assessment. The Highways Agency may require the developer to fund improvements to cater for development traffic.
   
  Road Hierarchy
4. The District's road hierarchy is set out in the Lancashire Structure Plan. This is reproduced below.
   
  Motorways
5. These are special roads as defined by Section 16 of the Highways Act 1988.
 
  • M6 - within the District
  Primary Routes
6. These are high quality routes linking major centres of population and provide for regional movements. They comprise trunk roads and the more important 'A' Roads. They form the highway network within the Strategic Transport Corridors.
 
  • A65 within the District;
  • A683/A687 from Heysham to Wrayton;
  Other Main Routes
7. These are good quality roads which acts as links between and into the main towns and between those towns and the Primary Routes.
 
  • A6 within the District;
  • A589 - from A683 at Lancaster to A683 at Heysham;
  • A683 - from A687 at Wrayton to District boundary;
  • A5105 - from A589 at Heysham to A6 at Bolton-le-Sands;
  • Lancaster City Centre Improvements (when completed)
  Distributor Roads (not defined)
8. These distribute traffic within towns and rural settlements. They are intended to cater for movements from locality to locality and to link these areas to the primary and other main routes.
   
  Other Roads (not defined)
9. Provide access to adjoining land or development.
   
  Policy on Development in Relation to Trunk Roads
10. The Department of Transport's policy is set out in Circular Roads 4/88. In summary the policy is as follows:
   
  For Motorways -
11. The Department has a strict policy of not allowing direct access from private development to motorways or motorway slip roads unless the development relates to motorway service areas, road junctions or motorway maintenance compounds. The Secretary of State will direct local planning authorities (LPAs) to refuse planning applications for development whose access arrangements breach this policy.
   
  For All-Purpose Trunk Roads (APTRs) -
12. On APTRs it is clearly necessary in general to restrict the formation of new accesses to them if they are to continue to perform their function as routes for the safe and expeditious movement of long distance through traffic. A particular strict policy is appropriate to fast stretches of rural roads and to trunk roads of near motorway standard.
13. Where a development is likely to generate a material increase in traffic (as defined in PPG13) either via an existing access (whether direct or indirect via a local road) or via an otherwise acceptable new access on to a trunk road, which would result in the access, or the main line of the trunk road, becoming overloaded, the Secretary of State would normally advise (but if necessary direct) the Local Planning Authority to refuse the planning application. Alternatively, if improvements could be designed to provide the additional capacity:
 
  • to the existing or proposed access to the trunk road consistent with the Secretary of State's 15 year design horizon normally applied to those schemes he initiates himself, and
  • to the main line of the trunk road to leave conditions no worse off on completion of the development,
14. the Secretary of State could advise (or again, if necessary, direct) the Local Planning Authority to impose conditions on any planning permission that the development should not occur unless and until those improvements have been carried out.
15. The Highways Agency would thus not expect to object to development consistent with the proposals in the local plan, subject to the completion of any highway works which it considered necessary and acceptable in relation to the trunk road and network.
