16 Route Window C13A Abbey Mills

Introduction 16.1 The main activities in this route window are sewer diversions, which are essential advance works

before the construction of the Pudding Mill Lane portal. The works are expected to take about 15 months.

16.2 The Crossrail alignment of the running tunnels at Pudding Mill Lane will require diversion of the Hackney to Abbey Mills and Wick Lane sewers. Between the Great Eastern Main Line at Wick Lane and the Abbey Mills Pumping Station, the sewers will be diverted north eastwards to run beneath the junction of Marshgate Lane and Pudding Mill Lane before passing beneath Claypole Road.

16.3 The diversion of the sewer through the Pudding Mill Lane Portal Worksite, between Wick Lane and Abbey Mills will require 1.3 km total length of tunnelling, four shafts (including two in Route Window C13) and construction of a new pumping station at Abbey Mills.

16.4 The works will involve two shafts, one of which is required for the insertion or recovery of a TBM; the other site is for access during and after the works. A new pumping station will be constructed at the Abbey Mills site.

16.5 There will be two worksites in this route window. From west to east they are:

Claypole Road Constructed on a soft landscaped area situated between Claypole Road, Bisson Road and Leggatt Road

Abbey Mills Pumping Station

At Abbey Mills, adjacent to the existing pumping station.

16.6 The maps provided at the end of this chapter present the main features of the route window and the assessed construction lorry routes.

Baseline conditions

16.7 Route Window C13A centres on the Abbey Mills residential area of east London in LB Newham. It lies south of A118 High Street and the proposed Pudding Mill Lane Portal Worksite (see Route Window C13), east of the River Lea and the Waterworks River, and west of Stratford.

16.8 Land use in the Abbey Mills area is predominantly residential. There is access to an existing pumping station at the southern end of Abbey Lane and allotments at the southern end of Bisson Road.

16.9 Abbey Lane is the major local distributor road in this area and forms a signal-controlled junction with the A118 High Street. Abbey Lane is closed to general traffic approximately 100 m east of its junction with Gay Road.

16.10 There are no waiting and loading restrictions throughout the Abbey Mills local area. Some vehicles have been observed parking obstructively near junction corners and other pinch points. Issues can be exacerbated at periods when parking demand is greatest ie weekday evenings and weekends.

16.11 There are bus routes on the A118 High Street and the Docklands Light Railway is easily accessible via nearby Pudding Mill Lane Station.

16.12 Low pedestrian flows have been observed throughout the Abbey Mills local area. The Greenway forms a traffic free part an east-west LCN route which utilises the landscaped Northern Outfall Sewer to traverse the Abbey Mills area.

The permanent works 16.13 Sewer diversion through the Pudding Mill Lane Portal Worksite, between Wick Lane and Abbey

Mills will require 1.3 km total length of tunnelling, four shafts (including two in Route Window C13) and construction of a new pumping station at Abbey Mills.

Worksite assessment

Abbey Mills and Wick Lane Sewer Diversion worksites

16.14 The diversion of the sewer through the Pudding Mill Lane Portal Worksite, between Wick Lane and Abbey Mills, will require 1000 m total length of tunnelling, four shafts (including three in Route Window C13) and construction of a new pumping station at Abbey Mills, adjacent to the existing pumping station.

16.15 A permanent access shaft will be constructed on a soft landscaped area situated between Claypole Road, Bisson Road and Leggatt Road, with a vehicular access and egress point on Claypole Road. The entrance will be conspicuously located and will not cause any significant adverse impact on local road users, pedestrians or cyclists.

16.16 Adjacent to the existing Abbey Mills pumping station, a shaft will be excavated to house a new pumping station and to facilitate tunnel drives for the new sewer, and to connect with an existing sewer. An existing vehicular entry and exit point will be utilised which is conspicuously located and will not cause any significant adverse impact on local road users, pedestrians or cyclists.

16.17 The worksite arrangement and associated lorry access and entry points are not predicted to cause any significant adverse impact on local road users, pedestrians or cyclists.

Lorry route assessment

16.18 Material, including excavated material will be delivered and removed by road only.

16.19 Construction lorries can access the pumping station worksite from the A118 High Street via Abbey Lane and Gay Road through an existing entry point.

16.20 Construction lorries can access the Claypole Road shaft worksite from the A118 High Street via Abbey Lane, Bisson Road and Claypole Road. Lorries can egress the site on Claypole Road back to the A118 High Street via Leggatt Road, Bisson Road and Abbey Lane.

16.21 Local bus routes serve A118 High Street. No significant impacts upon bus users or operators are anticipated since the number of lorries travelling along the route is predicted to be less than 30 per cent of the existing lorry traffic flow.

16.22 It is anticipated that a maximum of 10 lorry movements per day will be generated by the two worksites in this route window.

16.23 The daily flow of lorries generated by the worksite will not cause a significant impact.

Lorry holding area assessment

16.24 It is envisaged that adequate lorry holding provision is available on-site.

Mitigation and temporary impacts 16.25 There are no significant temporary impacts and therefore no mitigation measures associated with

this route window.

Mitigation and permanent impacts 16.26 There are no significant permanent impacts and therefore no mitigation measures associated with

this route window.
