This is not deemed an appropriate alternative due to the use of a motorway junction and highways established at the current location, need to divert vehicles on to alternative routes, causing congestion in the wider whereas this would not be the case for new locations area. This would result in potential adverse environmental effects associated with noise, air quality, human health, and effects on travellers, among others. It Is considered that the strategic alternatives options considered would not A Do-Nothing alternative was not considered an option and was therefore not address the objectives of the scheme and the diversion of traffic away from M6 considered in further detail.

Design Alternatives Option 5: Two new straight two-lane bridges and retain existing structures Walsall MBC has been working with Highways England to develop possible This option is for the construction of two new two-span concrete bridges (two transport solutions to improve M6 J10 and the outcomes of which are lanes wide each) and retention of existing structures. This option was discounted documented in Walsall Council’s Major Transport Scheme Concept Design (2013) as the continued use of the existing infrastructure would require extensive report. As part of the design development, several alternatives were considered and ongoing investment due to the current condition of the structures as the for M6 J10 and the report sets out six possible options for improving M6 J10 and two existing bridges are reaching the end of their serviceable life. This would are detailed in the table below: require a long-term programme of interventions such as night closures, traffic management/diversion with resulting additional congestion, which the Scheme Option 1 Two new straight two-lane bridges and flyover, demolish aims to mitigate, not to increase. existing bridges Option 2 Two new straight two-lane bridges and hamburger, demolish existing bridges Figure 5.1: Option 3a – Two new straight four-lane bridges and existing bridges demolished Option 3a Two new straight four-lane bridges, demolish existing bridges Option 3b Two new curved four-lane bridges, demolish existing bridges Option 4 Four new straight two-lane bridges, demolish existing bridges Option 5 Two new straight two-lane bridges, retain existing structures
Of the above solutions, options 3a and 3b (see Figures 5.1 and 5.2) were taken forward for further consideration and assessed fully in the Environmental Assessment Report (EAR). The remaining four options were discounted and therefore were assessed only at a high level in the EAR. Further detail on the options and the reasons for their discontinuance are detailed below.
Option 1: Two new straight two-lane bridges and flyover and demolish existing bridges Option 1 features a central ‘flyover’ principle in its design above Junction 10 and was dismissed at the preliminary stage. This was due to the design being unable to meet the desirable maximum vertical gradient for the ramp to tie into Bloxwich Lane, also it cannot be constructed within the footprint of the junction.
Option 2: Two new straight two-lane bridges and hamburger and demolish existing bridges The design included the addition of a central bridge across the junction to form a ‘hamburger’ style junction, which introduced an additional signal stage on each side of the circulatory. Including the central bridge along with the lack of circulatory storage space resulted in the weakening of the required benefits to address the transport problem as it was not considered to provide the benefits of vehicle congestion relief when compared with other options.
Option 4: Four new straight two-lane bridges and demolish existing bridges Construction of four new two-span concrete bridges (two lanes wide each) and to demolish the existing structures. This option was discounted as the modelling suggested that this solution would have provided insufficient capacity between the A454 Black Country Route and the B4464 Wolverhampton Road to accommodate vehicles travelling around the circulatory. Furthermore, the construction of four new bridges increases costs and reduces the cost benefit. M6 JUNCTION 10 - Highways Improvements Design and Access Statement | 12
Design Selection Process Figure 5.2: Option 3b – Two new curved four-lane bridges and existing bridges demolished During the optioneering process both Option 1 and Option 2 designs failed to provide significant benefits in future scenarios. The remaining four options which mirror the existing layout of the junction but increase capacity with larger bridges showed potentially significant benefits and were taken forward for design work.
The same design constraints were apparent for options 5 and 6 as neither can be constructed without departures from standard, as a Design Manual for Roads and Bridges compliant restraint system cannot be installed the existing structures.
The preferred option for the scheme was concluded as Option 3b comprising two new four-lane bridges with a circular build and demolition of the existing structures.
As stated above, many of the proposed options were discontinued at an early stage of the schemes development. However, options 3a and 3b were considered further in the EAR which examined the potential environmental effects for both scheme options. The EAR assessed each option based on various technical assessments including air quality, cultural heritage, landscape, nature conservation, geology and soils, materials, noise and vibration, people and communities, road drainage and the water environment, and effects on travellers.
The EAR therefore found that both options would have a comparable effect on the environment. Therefore, equal scoring for environmental factors was given for both Option 3a and Option 3b. Because of this, other factors considered in this process resulted in the selection of Option 3b.
Option 3b was subsequently chosen for the proposed scheme for improvements to M6 J10. 13 | M6 Junction 10 – Highways Improvements Design and Access Statement

5.4. Use and amount The proposed development is for a package of highways improvements at M6 J10 and comprises the construction of new curved bridges to be replace the existing structures. The application does not seek to change the permanent use of the land and will continue to be used as a highway and motorway junction serving the M6 northbound and southbound carriageways, A454 Black Country Route, B4464 Wolverhampton Road West, and A454 Wolverhampton.
A temporary construction compound is required for the scheme and this will be located east of M6 J10 on land currently occupied by either Bloxwich Lane Industrial Estate or John Hill & Sons Moorside. Only one construction compound will be required and this will be chosen in the post-consent phase of the scheme.

Highway Alignment Figure 5.5: Highway Layout of M6 J10 The overarching purpose of the scheme is to increase capacity of the M6 J10 roundabout. This is to be primarily achieved through increasing the amount of vehicle lanes from two to four on the overbridge widening the east quadrant from 2 to 5 lanes and widening at the west quadrant from 4 to 5 lanes (See Figure 5.5). In addition, it is proposed that other road lanes are increased at the following sections:
• The northbound M6 off-slip increases from four to five lanes at the approach to J10; • The westbound Black Country Route, going west from the J10 roundabout, increases from two to three lanes as far as the junction with Marshland Way; • Wolverhampton Road West, where the eastbound lane approaches J10, there will be an increase from two to three vehicle lanes; • The southbound M6 off-slip increases from four lanes to five where it meets the roundabout; • Where Wolverhampton Road meets J10 on the east side of the roundabout, there is a lane increase from three to five; and • At the junction between Bloxwich Lane and Wolverhampton Road, the overall road width will increase on Bloxwich Lane due to the installation of an enhanced pedestrian crossing, incorporating an island in the road.

Structures Figure 5.6: Plan of proposed new bridges at M6 Junction 10 In order to expand the lane capacity of the roundabout the existing bridges are to be demolished and be replaced by two new bridges. The two-new concrete and steel bridges will be constructed on the outside of the existing bridges and will be single-span thus removing he need for a central pier at the M6 motorway central reservation underneath, as shown in Figure 5.6.
Retaining walls will be constructed in each of the four corners of the roundabout in the following locations as shown on Drawing No. HE551484-MMSJV-SRW-RDBT- DR-CB-00021:
• In the north-west corner of the roundabout, in the area where Wolverhampton Road West and the northbound on-slip road to the M6 adjoin the roundabout, the retaining wall will be approximately 11m in length and up to approximately 1.0 and 2.5m in height and located between the northwest pylon and footway between B4464 Wolverhampton Road West and M6 northbound slip road; • In the north-east corner of the roundabout, the area where the southbound off-slip from the M6 and Wolverhampton Road adjoin the roundabout, the retaining wall will be approximately 384m in length and up to approximately 0.7m and 6m in height. The retaining wall will be located between the M6 southbound slip road adjacent to the footpath and extends as far as the Bloxwich Lane junction; • In the south-east corner of the roundabout the retaining wall will be located between in where Wolverhampton Road and the southbound M6 on-slip adjoin the roundabout and adjacent to the southeast pylon and private land. The retaining wall will be approximately 203m in length, and up to approximately 0.7m and 2.1m in height; and • In the south-west corner of the roundabout the retaining wall will be located from the northbound slip road from the M6 to where the Black Country Route adjoins the roundabout, the retaining wall will be approximately 20m in length and up to approximately 0.7m and 4.4m in height.
On the west side of the junction, the southern side of the A454 Black Country Route, where the westbound lane leaves the M6 J10 roundabout (in the vicinity of the northern end of Bentley Mill Lane), one noise barrier will be installed. This will be at a height of 2m above the existing wall (which will be retained) for a length of approximately 87m. On the eastern end of this barrier, for a distance of 108m, it will be 3.8m high from the ground, as there is no existing wall to build it upon. The total length of the noise barrier will therefore be 195m.
In the north eastern corner of M6 J10, a second noise barrier will be installed, 4m high, for a length of 165m.

Junction Strategy and Traffic Signalling Lighting Gantries and Signage The M6 J10 roundabout will be fully-signalised and pedestrian crossings will be fully incorporated into the The lighting and gantry design for the proposed scheme is shown in Figure 5.7 and will be similar in nature signal phasing to ensure no additional driver delay. to the existing layout. However, additions are proposed in the form of new lighting columns will be removed. Lighting will be of a similar-strength to the present conditions. The junction between Wolverhampton Road and Bloxwich Lane will continue to be signal-controlled with the timing coordinated with those at the adjacent M6 J10. Up to nine gantries will be installed to provide signage for vehicle users as the wider highway widths necessitate some above-road signage to ensure visibility to all drivers. These have been located to minimise Additional lanes will be provided on the overbridges of the M6 J10 roundabout and on some approach roads the visual intrusion on residents as much as possible through the use of existing screening. to the roundabout. The lanes of the roundabout, and the approach roads, will be comprised of feeder lanes. Signage (including overhead gantries where appropriate) will inform road users of the correct lane to use. The proposed gantries will be at a height of approximately 8.5 metres (from ground level to the top of the signage) and are required to ensure visibility of directions to all road users, as necessitated by increasing the number of road lanes as road-side signage may be blocked from view by vehicles in neighbouring lanes.
The remaining road signage will be of a similar design to those at present with other signage located parallel to the roadway rather than above it.

Construction Compounds Drainage The application proposes two options for construction compound areas to be used during the construction The existing drainage around M6 J10 collects runoff from both impermeable and permeable areas and is discharged into Sneyd Brook [subject to confirmation]. The proposed layout intends to maintain the existing phase. Both compound options are east of M6 J10 and can be accessed via the existing highway.

The location of the compounds is illustrated in Figure 5.9.

6. Landscaping
6.1. Proposed Landscaping Figure 6.1: Site Clearance Plan
The scheme proposes significance clearance of the existing surrounding landscaping, as shown in the Site Clearance plan (Drawing No. HE551484-MMSJV-HAC-000-DR-CH-00001) at Figure 6.1.
Landscaping Plans have been prepared by Mott MacDonald are provided at Figure xxx and each element of the proposed landscaping is discussed in further detail below:
Highway Verges within the Roundabout The area within the roundabout will comprise a native woodland mix consisting of Betula Pendula 30%, Alnus Glutinosa 30%, Acer Campestre Prunus Spinosa Tilia Cordata and Quercus Robur planted as whips. It is proposed that scattered throughout the area are a number of more mature Pinus Sylvestris trees to provide a level of instant impact with the planting. The embankments to the central roundabout will be planted in a grass mix which should open up views of woodland planted mix at the centre of the roundabout.
Motorway Approaches A secondary woodland planting mix consisting of Populus Nigra 10%, Alnus Glutinosa 20%, Acer Campestre 30%, Crataegus Monogyna 20%, Rosa Canina 20% has been proposed along the northern and southern approaches to M6 J10 with more mature Pinus Sylvestris trees planted to form an avenue of trees on each side of the motorway.
Central Reservations The central reservation approaching from the south is planted with a mix of ornamental cherry trees and the eastern approach has a mix of Quercus Palustris and Liquidambar Styraciflua planted in a line within the central reservation. Both sets of trees will provide seasonal displays of colour and visual interest throughout the year. The western approach has screen planting for properties which are located in close proximity to the Site. Screen planting with larger trees has also been proposed for the north-eastern area adjacent to Wolverhampton Road to screen properties from the highway.

8. Summary and Conclusion
Mott MacDonald has been instructed by Walsall Metropolitan Borough Council Figure 8.1: Visualisation of proposed works at M6 Junction 10 (WMBC) to prepare a Design and Access Statement in support of a Full Planning Application for series of highways improvement works to M6 Junction 10.
The proposed development seeks to improve highway capacity and reduce vehicle delays through the construction of new widened bridges, improvements to the junctions slip roads, installation of traffic signals, widening of the nearby Bloxwich Lane Junction, modifications to part of the Black Country Route along with associated landscaping and other complimentary works. The full development description is as follows:
“Planning application for two replacement wider bridges over the M6 Motorway and a package of highway improvements comprising, enhanced motorway slip roads, installation of traffic signals, widening of the Junction of A454 and Tempus Drive Bloxwich Lane, modifications to the Black Country Route, landscape works and associated infrastructure and engineering works.”
The junction suffers from capacity issues resulting in vehicle congestion and delays along the strategic highway network. In tandem with this the existing structures at the junction are in need of urgent repair. Highways England carried out a host of inspections throughout 2012 on the existing bridges of M6 J10 which indicated signs of ongoing deterioration. The resulting Inspection Report suggested replacement of both bridges would be required within 3 to 4 years of 2012. Further and more recent inspections were also undertaken by Highways England, however these did not indicate further appreciable deterioration. However, Highways England’s Professional and Technical Solutions have agreed to still replace the bridges to avoid any future maintenance interventions from impacting the capacity of the M6 and Junction 10.
The Design and Access Statement has set out the design concepts that have been applied to the development. It demonstrates that the proposed scheme represents the best design solution taking into account the sites surrounding and the need for an appropriate solution to solve the issues present with the existing arrangements of Junction 10.
The design of the works has been developed with due regard to the relevant planning policies in respect of the Statutory Development Plan, National Planning Policy, and Supplementary Planning Guidance. Particular regard has Source: Highways England (2017) been had to Policy ENV3 of the Black Country Core Strategy, Policies ENV32, ENV33, and ENV34 of the Walsall UDP and Section 7 of the National Planning Policy Framework.
