Non-Technical Summary - February 2005

Introduction

This document presents a summary of the environmental effects of the M6 Extension from Carlisle to Guards Mill, which are set out in more detail in the Environmental Statement (E.S.) for the Scheme. The E.S. has been published in accordance with Directive 97/11/EEC as applied by Section 105A of the Highways Act 1980 as amended. The E.S. supports the published draft Highway Orders and the draft Compulsory Purchase Order which is due for publication in the near future (legal documents which would allow the Scheme to be built). Details of where the E.S. can be seen for closer inspection are detailed towards the end of this summary under the heading of "Further Information".

Why the Improvement is Needed

The A74 between Carlisle to Guards Mill is the last "missing link" in the motorway network between London and Glasgow. This dual carriageway section of trunk road has several minor road junctions and therefore mixes relatively low-speed local traffic with high-speed trunk road traffic. It has a poor accident record and causes driver frustration, resulting from heavy goods vehicles using the outside lane of each carriageway. The upgrade of this section to motorway standard would bring the following benefits to road users:

• a reduction in the number of accidents on the route;
• the provision of more carriageway space for emergency services attending accidents;
• the provision of more carriageway space to enable traffic flows to be maintained following an accident;
• a reduction in driver frustration;
• an improvement in accessibility for users; and
• the provision of more predictable journey times.

The needs of local traffic and non-motorway users would be catered for by building anadjacent all-purpose road (APR) along the full length of the Scheme.

The Scheme

The A74 Trunk Road is a vital strategic road connection between the M6 in England andthe A47(M) in Scotland, and also provides important community links locally. It is proposed to upgrade the existing road from the end of the M6 motorway at Junction 44, Greymoorhill, to the start of the A74(M) at Guards Mill, just to the south of the Scottish Border at Gretna. The length of this section is approximately 8.6km (5.4 miles). The existing trunk road consists of a dual 2-lane carriageway and the proposal is to widen the route to a 3-lane motorway. The route of the Scheme is illustrated on the plan in the centre of this leafl et.

Although the new motorway would generally follow the line of the existing A74, the proposals also involve a number of deviations from this route. The main deviation would be north of the River Esk, where the motorway would follow a line further to the west of the A74, crossing over the West Coast Mainline Railway (WCML) on a new bridge, before rejoining the line of the A74 south of Guards Mill. The Mossband Viaduct (which carries the A74 over the WCML at present) is in poor condition and would be demolished following construction of the new bridge.

A minor deviation is also proposed just south of the River Esk, where the southboundcarriageway of the motorway would follow a line slightly further to the east of the A74,crossing the River Esk on another new bridge. At Todhills, the motorway would also deviate slightly to the west for a short section. Lighting is not proposed along the motorway, however, the services areas would be lit.

All-Purpose Road (APR)

The APR would be located to the west of the new motorway over its entire length and would cater for local traffic and nonmotorised users. Some sections would utilise the existing local road network (mostly at the southern end along Parkhouse Road), whilst others would be constructed across land adjacent to the new motorway. Existing side road accesses on to the A74 would be stopped up, however, the overbridges crossing the A74 would be retained as partof the Scheme. These structures would link in with the APR.

Disruption Due to Construction

The A74 would remain open throughout the construction works, with two lanes of trafficavailable in each direction for the majority of the time, to minimise disruption to vehicletravellers.Any planned lane closures would occur during off-peak periods. However, theworks would require signifi cant quantities of stone and other building materials to bedelivered by road-going lorries. The number of additional vehicles has the potential tocause congestion during the road works. Therefore, deliveries would be carefullyprogrammed to minimise disruption caused to other road users. Vehicles would also berouted to avoid, as far as possible, residential areas, schools, aged person's homes andother buildings with sensitive users. These routes would be agreed with the localauthority prior to the start of construction. Material would be delivered throughoutthe duration of the works and temporarily stockpiled to ease the supply difficulties.Temporary stockpile areas would be located on land adjacent to the A74 which would berequired for the duration of the construction works. Dust and noise generated duringconstruction would be limited by good site management procedures.

Environmental Effects of the Scheme

The Scheme has been developed to minimise its effects on the environment. The keyenvironmental benefits of the Scheme are presented in the table below:

Environmental Aspect	Benefit
Land-take	The area of land to be taken for the Scheme has been reduced as far as practicable.
Air Quality	The Scheme would not cause roadside air quality levels to exceed Government limits. Specific measures would be taken to minimise the amount of dust generated during construction.
Noise	Noise fences would be installed at sensitive locations and would reduce noise levels at 71 residential properties in the vicinity of the Scheme. The timing and duration of particularly noisy operations would be strictly controlled.
Ecology and Nature Conservation	Sites of nature conservation importance would be avoided where possible.
Landscape and Visual Effects	Local residents and vehicle travellers would experience improved views. Once mature, new planting would blend the Scheme into the surrounding landscape.
Water Quality	The drainage for the Scheme would involve measures to reduce significantly the risks of pollution to local rivers and streams and would be an improvement on the currentsituation.

Air Quality, Noise and Vibration

The Scheme would not result in significant increases in roadside levels of air pollutants,such as nitrogen dioxide (a gas emitted from car exhausts) and dust. Therefore, local air quality would still remain within the Government's air quality limits.

Levels of carbon dioxide (the principal "greenhouse gas") would increase by 2% as a result of the Scheme, compared to the future predicted levels without the Scheme. This increase is largely because cars, and to a lesser extent, lorries would be travelling slightly faster on the new motorway, due to the provision of a third lane to each carriageway, relieving some of the current congestion.

In order to reduce the high noise levels currently experienced at residential properties close to the A74, noise fences are to be incorporated at five sensitive locations: Mossband; Metal Bridge; Todhills; Parkhouse Road; and High Crindledyke.

Following their installation, 71 residential properties would benefit from a reduction intraffic noise. If the Scheme did not proceed, and traffic flows continue to grow aspredicted, 100 properties would experience an increase in noise levels. The timing and duration of any noisy operations during the construction of the road would be strictlycontrolled.

Cultural Heritage

The Scheme would not adversely affect any scheduled ancient monuments or their settings, including the Hadrian's Wall World Heritage Site. However, distant views to and from the Registered Battlefi eld of Solway Moss would be slightly affected. No listed buildings would be adversely affected, and the Scheme provides an opportunity to enhance the setting of onelisted building, Floristonrigg Farmhouse through additional tree planting. One unlisted building of potential historic interest, Bents Cottage, would be demolished. This building would be fully recorded by written records, photographs and drawings prior to demolition.

Ecology and Nature Conservation

Non-Technical Summary - February 2005

Ecology and Nature Conservation

The Upper Solway Flats and Marshes lies close to the Scheme and is protected under UK and European law. It contains one of the largest areas of mudfl ats in the UK and supports several rare species of plants and habitats, as well as large populations of wildfowl and wading birds. The Scheme would not cross the site, and its effects would be limited to noise and visual disturbance to birds during construction works.

The new River Esk bridge would be sensitively designed and constructed. Construction works would be limited to a small area to further reduce the impact of the Scheme on the River Esk.

There are four sites of county wildlife importance in the vicinity of the Scheme. However, only Rockcliffe Moss and Harker Moss would be directly affected, losing just 2% of their areas from the periphery of these sites. The Scheme would, however, offer an opportunity to enhance the quality of these "mossland" habitats (which have become "dried-out") for wildlife by means of raising water levels (see Geology and Soils for further details).

Several other habitats of local nature conservation value have been identified, including areas of marshy grassland, "important" hedgerows and species-rich verges. In addition, red squirrels, bats, barn owls and reptiles are particularly important species which may be affected by the works. Specific measures are proposed to protect, and wherever possible, enhance the status of these species and habitats.

Badger and otter-proof fencing and associated tunnels would be used to guide these species under the motorway, reducing road deaths of these animals to a level well below that on the existing A74. A comprehensive programme would be designed to monitor the impacts of the Scheme on wildlife and the effectiveness of the compensatory measures proposed.

Landscape and Visual Effects

The Scheme is set within a varied landscape, ranging from urban fringe on the northernoutskirts of Carlisle, to areas of lowland peat bog at Rockcliffe Moss and Harker Moss. In particular, the area north of the River Esk has a pleasant quality, comprising estuarinefarmland around the Esk which leads on to the Solway Firth; designated as an Area ofOutstanding Natural Beauty (AONB).

The Scheme would reduce the adverse effect that the A74 has on the surrounding landscape and views at present. This would be achieved by planting native species of trees and shrubs, which, once mature, would help to blend the Scheme into the landscape and improve the views experienced by nearby residents.

The removal of existing roadside planting at the southern end of the Scheme would openup views of the wider landscape for vehicle travellers. Open and attractive views to thenorth of the River Esk, which encompass the fringes of the Solway Firth and distant viewsof moorland and the Lakeland Fells, would remain available with the Scheme.

Land Use

An assessment has been made of the effects of the Scheme on land used for agriculture,by the community, or by other businesses. The Scheme would not affect any land used by the community, such as the Hespin Wood Travellers' Site or the Kingmoor Nature Reserve on the northern outskirts of Carlisle. Furthermore, the Scheme would not affect any planned developments in the area. A small amount of land would be lost at the Hespin Wood Landfill site. However, this would be confi ned to the periphery of the site and therefore the effect would be minimal. The areas of the site used for landfill purposes would remain unaffected.

The Scheme would result in the demolition of five residential properties and the permanent loss of 40ha of agricultural land. The operations of twelve farm businesses (including full and part-time enterprises) would be affected by the Scheme.

Vehicle Travellers and Non-Motorised Users

The existing A74 causes high levels of driver stress at times, particularly from slow-moving farm traffic and HGVs in the outside lane overtaking slower vehicles, sub-standard local accesses, and narrow lay-bys. The Scheme would lower driver stress by reducing frustration and improving safety for users of the Scheme.

The existing service areas south of Todhills would remain to provide traveller carefacilities for motorway users. However, direct access to the farm-shop at Floristonwould only be available from the new all-purpose route.

The Scheme would result in one footpath being severed where it abuts and crosses the A74 at Griershill, since pedestrians would no longer be allowed to cross the motorway. However, this footpath currently leads to a "dead-end" at the A74 fence line, and the Scheme would allow its connection back to the existing highway network at Low Harker. No bridleways would be affected. The allpurpose route would assist the provision of the proposed national cycle route, which Sustrans (a charitable organisation promoting cycling) plans to create betweenGretna and Carlisle. This would be achieved by the APR, which would provide cyclists withsafer and direct route between Carlisle and Gretna. The APR would also enable localjourneys to avoid the motorway, providing safe, direct access to schools and other community facilities.

Water Quality and Drainage

At present, drainage water from the A74 flows directly into local watercourses with nopollution control, or containment for accidental spillages. However, under the Schemedrainage proposals, ten new drainage ponds would be constructed to store, clean and control the discharge of road drainage before it enters local streams and ditches. This would result in a net improvement in the quality of these watercourses. During construction, pollution control measures and good site management practices would reduce the risk of local watercourses being accidentally polluted.During the construction of the River Esk bridge, artificial "islands" would need to be temporarily installed within the river channel for the works to take place. These "islands" would be carefully designed, installed in phases and removed as soon as possible to minimise their effect on river levels and flows. Once constructed, the new bridge would not significantly alter the flow or level of the River Esk.

The Scheme would encroach slightly into an area of floodplain between the River Esk and Guards Mill. This would result in a minor reduction in the floodplain's overall capacity to store water during a flood event. However, the effect of this would be minimal, since during a flood, water within the floodplain would only be expected to rise by approximately 1cm as a result of the Scheme.

Geology and Soils

The ground investigation has revealed that there are relatively few contaminated sitesalong the Scheme. Consequently, the risk posed by contaminated land to members of the public and construction workers is low. These risks would be reduced further by the adoption of good hygiene practices and safe-working procedures during construction works.

Groundwater beneath the site would also be protected from pollution during constructionby the adoption of good site management practices.

However, there is a minor risk that groundwater could be drawn away from the "mossland" sites (which could further accelerate the "drying out" of these sites) and the landfill sites as a result of the materials used to construct the Scheme. The significance of this risk would be further assessed during the detailed design and construction of the road and, ifrequired, mitigation measures implemented. These could include the isolation of roadexcavations, to maintain the groundwater levels at these sites.

Under the Scheme drainage proposals, water from several of the new drainage ponds would enter ditches running through the "mossland" sites. This would help to maintain the groundwater levels at these sites, further enhancing their long-term sustainability andnature conservation value.

Policies and Plans

Upgrading the A74 to motorway was included in the Roads Programme in 1989. It has therefore been included as a proposed road improvement in both Regional Planning Guidance and the County Structure Plan. The Local Plan also identifies a protected route for the Scheme.

Overall, the Scheme would not significantly hinder the implementation of any plans orpolicies.

What Happens Next?

Depending on the nature and number of any objections received, a Public Inquiry maybe held before an independent Inspector. If a Public Inquiry is to be held, all thosewho have responded would be notified individually at least six weeks beforehand and notices would appear in the local press. All comments received would be made available to the Inspector who may decide to make them public. Publicity would be given to any alternative proposal received. The Secretary of State for Transport would consider the Inspector's recommendations (in the event of a Public Inquiry) and decide on the way forward.

Public Exhibition

A public exhibition of the proposals will be held at the Rockcliffe Community Hall,Rockcliffe on 7th (2pm to 8pm) and the 8th of February 2005 (10am to 8pm).

Detailed plans and general details of the proposals together with proposed measuresto reduce the environmental impact will be on display.

Representatives of the Highways Agency, their Contractor and the design team willbe available at the exhibition to explain the proposals.
