PLANS AND SPECIFICATIONS OF CAMBRIDGE CHESTERTON / ABBEY FOOT / CYCLE BRIDGE (SCHEME 2018)

The location and general plan layout of Chesterton/ Abbey Bridge are shown on the plan marked “The Cambridgeshire County Council (Construction of Cambridge Chesterton / Abbey foot / cycle bridge) Scheme 2018” sealed with the Common Seal of the Cambridgeshire County Council and deposited at Shire Hall, Castle Hill, Cambridge CB3 0AP.

POINTS OF COMMENCEMENT AND TERMINATION

North Approach – Top of the North Abutment

Commencing from a point on the North bank of the River Cam 42.23 metres east of the existing railway bridge and situated on the Halingway towing path.

Ditton Meadows Approach – Top of the South Abutment

Terminating at a point on the South bank of the River Cam, 35.79 metres east of the existing railway bridge where the new bridge approach meets the existing Jubilee Cycle Path (Sustrans National Cycle Route 51).

Navigation Span

The bridge has a clear span of 44 metres (between abutments), spanning diagonally across the entire width of the River Cam (25 metres approx.). The bridge runs parallel and to the east of the Chesterton railway bridge. It will be constructed 10 metres away from the railway bridge.

Headway and Waterway

The navigation waterway is unrestricted for the full width of the river except where locally constrained by the jetty beneath the existing railway bridge. At which point the Waterway measures 28.97m. The soffit level of the bridge is +7.03m AOD, giving a 3.17m clearance above the current air-draught requirement set by the nearby Chesterton railway bridge.

Overall Dimensions

The proposed bridge consists of a segregated deck surface of separate lanes for pedestrian and cycle traffic separated by a white line.

The total clear width across both lanes at the abutments is 4.51 metres, with a wider section at the middle of the bridge of 4.92 metres. The bridge will carry a 2.69 metres wide cycle path and a 2.22 metres wide footpath at its widest point. The total clear width across both lanes at the abutments is 4.51 metres.

The structural parapet varies from a height of 1.1m (1.4m on the cycle side) above the deck at the abutments, to 2m above the deck at mid-span.

The length of the south ramp structure is 87.60 metres, whilst the north ramp is 81.3 metres long.
