Highways 1. Introduction

The modernisation of England’s motorways and major A roads, also known as the strategic road network (SRN), is making a vital contribution to economic wellbeing and growth. This Route Strategy – one of 18 such reports – provides a statement on the current performance of, and perceived pressures on, the London Orbital and M23 to Gatwick route to inform the planning of future investment.

The SRN supports national and local economic prosperity by: ▪▪ linking together major cities ▪▪ connecting with extensive local road networks ▪▪ providing links to major ports, airports, and rail terminals ▪▪ enabling good access to regions and cross-border routes between the nations of the

The establishment of through the Infrastructure Act 2015 has changed fundamentally the way we plan investment in the network. Funding is now determined every 5 years, in the Road Investment Strategy (RIS), which is set by Government. We are currently delivering on the commitments that were set out in the first RIS covering 2015 to 2020, which are already making a difference for road users across the network. At the same time, we are working closely with the other 3 bodies with statutory responsibility for the RIS – , Office of Rail and Road and Transport Focus – on preparing for the next RIS (RIS2) for the period after 2020.

The M25 London Orbital and M23 to Gatwick route passes through Kent, , , and , the unitary boroughs of , and the Royal Borough of Windsor and Maidenhead, through the area of Slough and along the boundaries of the of Hillingdon, Enfield and Havering.

The route is made up of the and a number of roads adjoining it. These roads include: the A282 Crossing; KEY the M23 from the M25 to junction 9a and London Oribtal and Airport Way to Gatwick; the M4 to junction M23 Gatwick route 5; the A13 and A1089 from M25 junction SRN 30 to Docks; and all motorway and trunk road spurs within the M25 (except M40 junctions 1 to 1a). It covers almost 200 miles; most of the route is motorway with the M25 section being mostly 4 lanes in each direction but varying between 6 lanes (junctions 14-15) and a 2-lane link road at junction 5. The trunk roads vary from a single lane on the A23 and the end of the A1089, to 3 lanes in most other cases. The M25 south west quadrant (between junctions 10 and 16) experiences some of the highest volumes of traffic on the SRN, with a 2-way flow of around 200,000 vehicles per day. Compared to other parts of the SRN, the section has a relatively high proportion of commuter traffic travelling only 1 or 2 junctions, for example, between Surrey and West London. , with direct access to the M25 and M4, attracts movements associated with handling more than 75 Reproduced using Ordnance Survey data © Crown Copyright 2016 million passengers a year (over 200,000 per day) and 1.5 million metric tonnes of Figure 2.1 - Route overview map freight per year. For airport expansion the Government’s preferred option is a new north-west runway at Heathrow Airport.

Dartford is the only river crossing on the SRN east of London and is also one of the more congested SRN sections. Capacity issues already experienced at the and its approaches will become more significant due to the need to accommodate growth in , Thurrock and that associated with the , which is one of the biggest growth areas in Europe. The A13 and A1089 serve Tilbury docks, Lakeside and port and are dominated by freight traffic. Near the M25, the A13 carries around 100,000 vehicles per day. At Tilbury, the A1089 carries around 22,000 vehicles per day. The north side of the M25, particularly at junctions 21a-27, has a relatively high proportion of freight traffic connecting from the Midlands/North and the access points to the continent at Thames Gateway and the Kent Coast. The network here also needs to support adjacent growth, for example, in the Upper Lee Valley, and around . The M23 provides access to , and Crawley. The M23 experiences higher flows on Fridays and Sundays and in holiday periods because of coastal bound and airport traffic. In terms of its strategic economic function, the route services relatively short local commuter movements to and from as well as traffic to and from 3 London airports and shopping centres at Lakeside, Bluewater and Brent Cross. In addition, as a part of the Trans-European Transport Network (TEN-T), the route facilitates sub-regional and national movements between 8 adjacent routes (East of England; Kent Corridor to The M25 south west M25; South Coast Central; M25 to Solent; London to quadrant (between Wales; London to Scotland West; London to Leeds; and London to Scotland East), including freight movements junctions 10 - 16) to and from the South Coast, Kent and Thames Gateway coastal ports. experiences some of the The route also acts as a main between highest volumes of traffic strategic radial routes into and out of London and as a bypass of the capital.

Technology provision varies along the route. The London Orbital is mostly controlled motorway (other than junctions 3-5 and the A282 Dartford Crossing) and has Variable Message Signs (VMS) and Motorway Incident Detection and Signalling (MIDAS) throughout. There are sections of all lanes running from junction 5-7 and 23-27. Technology on the radial motorways is less extensive and largely absent on the trunk road network. Most of the route, including all spurs and the M23 from within the M25 to the A25 Road overbridge south of M23 junction 8, is managed, maintained and operated as part of a privately financed design, build, finance and operate contract (DBFO) which runs for 30 years (until 2039).

This chapter outlines the emerging issues raised by stakeholders and More free-flowing network is supplemented by Highways England information. Many motorway junctions in this part of the SRN experience capacity issues, causing congestion, delays and unreliable journeys during much of the day. The M1, The following text and figures within this chapter provide M11, M4 and A23 radial routes all suffer from peak hour a summary of the information collected and applied to traffic flows into and out of London. our strategic themes. The route is consequently one of the worst for journey experience, with the M25 cited as being the most problematic road to join and exit because of traffic A safe and volume, congestion or traffic queuing and delays caused serviceable network by accidents or roads closed (Transport Focus). Particularly around the south west quadrant of the M25, capacity issues are exacerbated by drivers making Sections on this route which have been identified as short hops of 1 or 2 junctions, causing weaving, delays having some of the worst safety issues on the SRN are and affecting journey time reliability for other users.

The lack of M25 motorway services from junctions 12-21 also represents a gap in the provision of safe rest facilities for drivers and potentially affects road user satisfaction.

This is compounded by shown across Figures 3.1 to 3.3. a lack of coordination between sets of adjacent traffic signals at some locations. A lack of convenient interchanges with rail services has An improved environment been cited as an issue to address.

The route passes through a variety of areas experiencing different environmental challenges. Air quality and noise issues are problematic at many locations. Almost 200 Noise Important Areas have been identified, for example at , Leatherhead and . A number of locations are within or close to Air Quality Management Areas (AQMAs) and nitrogen dioxide emissions are frequently above statutory limits and close to sensitive receptors on a number roads, for example, on the M25, the A282, the M1 and the M11. The M25 passes through 3 Areas of Outstanding Natural Beauty (the Kent Downs, Surrey Hills and Chilterns), which are vulnerable to visual impacts. Inclement weather can cause issues at some locations on the route. For example, the M25 between junctions 7 and 8 is vulnerable to snowfall and ice formation while QEII bridge closures on the A282 at Dartford can be caused by high winds, resulting in severe delays. Some links (for example, the M1 junctions 4-5) can flood during intense rainfall events.

Diversionary Routes An essential facet of a resilient road network is the ability to effectively divert traffic away from closed carriageways in the event of an unplanned incident. The map indicates the diversionary routes that currently exist on this route and that have been agreed with the local road network operator. However, it should be noted that the provision of these routes is dependent upon the nature of the KEY incident and the suitability and availability of the surrounding network. In some instances, Route the diversion route may not be suitable for HGV traffic or might not be available due to Diversion road network via local road events on the local road network. A review is currently underway to improve the quality and Strategic road network coverage of these routes, and to improve the traffic management procedures that are relied upon to implement these routes in the event of Figure 3.4 - London Orbital & M23 to Gatwick diversionary routes a carriageway closure.

Maintaining the strategic road network We carry out routine maintenance and renewal of roads, structures and technology to keep the network safe, serviceable and reliable. We also ensure that our contractors deliver a high level of service on the SRN to support operational performance and the long-term integrity of the asset. The heavy year-round use of all our routes means that they require regular maintenance and inspections for repairs to keep them fully operational, in order to support economic growth. Our maintenance regime focuses on 4 key aspects of the routes: road surfaces, bridges and structures, drainage and earthworks. The summary condition of each on this route is set out below:

Road surface The surface condition across the route is considered to be sound or having some deterioration with less than 0.5% having severe deterioration that would require focused investigation.

Findings from the research phase will feed into Highways England’s Strategic Road Network Initial Report, expected to be published later this year, which will outline Highways England’s ambitions for the network across 2020–2025 and beyond. The Initial Report will be the subject of public consultation.

29 London Orbital & M23 to Gatwick Route Strategy

In the finalmobilisation phase, we will set out a Delivery Plan with a detailed programme of investment to be carried out in 2020 to 2025 on the basis of the commitments in RIS2. Continued investment in modernisation, maintenance and operation will further improve the road network on top of the measures and schemes currently being undertaken, and will allow us to further support users of the strategic road network and the UK’s economy. The rigorous process of developing RIS2 should ensure that the best use is made of taxpayers’ money and that investments have the maximum impact. The views and perspectives of different stakeholders, including motorists, are important to us. Stakeholders may also wish to contact one of the partner organisations. For example, stakeholders can keep up to date with Transport Focus’ work, by signing up to their monthly electronic newsletter Road User Voice. Alternatively, stakeholders may prefer to make their views known through one of the many organisations involved in RIS2. They include the AA, RAC, RAC Foundation, Road Haulage Association, Freight Transport Association, Campaign for Better Transport, Confederation of British Industry and many others. We will provide information about the process and emerging findings at events for representative organisations in spring 2017. At the same time, we are developing the dialogue with emerging STBs, local government, LEPs, business groups and environmental organisations. We want to align our analysis, and eventually our decision-making, with that of other organisations, so that we can maximise the benefit of investment, for example focusing on improving the interconnectivity between different modes and between the strategic and local road networks. This should lead to a richer discussion during public consultation on the Strategic Road Network Initial Report.
