A229 Blue Bell Hill
The A229 Blue Bell Hill stretches between Junction 6 of the M20 in Maidstone and Junction 3 of the M2 at Blue Bell Hill village. This section of road is a key strategic link between the M20 and M2, and between Maidstone and Medway.
Improvements are needed to increase journey time reliability, reduce delays and enhance road safety on the route.
This scheme is still in an early phase of design and further modelling and assessment work will be done to finalise a design that meets the scheme objectives.
In September 2020 there was an early engagement consultation to ask for feedback on 3 possible options. From the consultation and further development work, options 1 and 2 have been taken forward for further investigation and option 3 was dropped from the proposals. The consultation brochure and report can be viewed in the scheme documents section.

This scheme is currently estimated to cost up to £199 million. We have put in a bid to the Department for Transport’s (DfT) Major Road Network funding programme for ‘Large Local Major Schemes.’ If successful, this will cover 85% of the costs of the scheme. The remaining 15% will be from developer contributions and other government funding opportunities.
This scheme is needed to tackle high levels of congestion, concerns regarding road safety, poor air quality and to support local growth and additional traffic from the Lower Thames Crossing (LTC).
The overall aim of the scheme is to improve journey time reliability and road safety. This will allow the road to accommodate an increase in future traffic, expected as a result of the Lower Thames Crossing and proposed local developments, while providing suitable routes and facilities for public transport, pedestrians and cyclists.
The objectives of this scheme are to:
- improve journey time reliability at the M2 Junction 3 and M20 Junction 6 interchanges of the A229
- reduce congestion along the route
- enable the local area to develop in accordance with population and housing growth predicated under Local Plans
- reduce the impact of additional traffic from the Lower Thames Crossing and allow the Lower Thames Crossing to maximise potential benefits it can provide for the Kent area
- improve road safety and address known accident hotspots
- make best use of existing assets including land and highways
- provide suitable routes and facilities for public transport
- provide safe and improved routes for pedestrians and cyclists
- improve air quality, particularly in the Air Quality Management Area
- protect and enhance the local environment.
The Department for Transport (DfT) have now asked us to provide some more information before they determine whether our business case submission has been successful for funding for the next stage of the work.
The scheme is still in an early phase. Further detailed design work will be required before construction could begin including:
- more detailed development of the options to establish a preferred scheme
- refining and developing the design of the chosen option
- development of environmental mitigation plans
- further engagement with the community and other stakeholders
- agreement of funding
- planning and other statutory consent
- development of construction plans to manage both the timing of works and impacts on traffic during construction of the scheme.
The forecasted timescales for this junction improvement scheme, should our business case submission be successful, are:
- submission of the next stage of the business case to the DfT including details of the preferred scheme – summer 2023
- planning permission and consents – spring 2023 to summer 2024
- further detailed design – summer 2023 to summer 2025
- submission of full business case to the DfT – autumn 2025
- construction to begin – spring 2026
- completion of scheme – summer 2028 (aim to be completed before the Lower Thames Crossing opens to traffic).
