The jetty will be closing in August to facilitate the works.
Initial works have included setting up the site depot, construction of a 350m of 'haul road' along the edge of Ditton Meadows to the bridge location, environmental and engineering surveys and clearance works. Off-site the bridge is being fabricated in a factory in Yorkshire.
Works will commence on site on the bridge structure this summer. Unfortunately, these works will necessitate the closure of the jetty under the railway bridge, partial closure of the river and full closure of the river to all access for a few hours at a time. These closures are needed to create a safe working environment for piling and construction of the bridge base. The jetty will also be replaced as part of these works. The works will involve the use of heavy machinery and GCP apologises in advance for the noise.
GCP says: "We are working closely with Conservators of the River Cam to reduce the impact of the necessary river closures on access. Our contractors, Tarmac Infrastructure, will make every effort to ensure that full closures of the Cam take place outside of peak rowing times.
"In order to keep the jetty open for as long as possible and to be responsive to works progress, the date and exact timings of the closures will be confirmed on signage by the jetty and on routes to the area. We anticipate the closure taking place from August 2019 and running through to Summer 2020, although if it is possible to open the path earlier every opportunity will be taken to do so.
"The jetty under the railway bridge forms part of the National Cycle Route 51. We recognise that this is a popular route and diversions for pedestrians and cyclists will be put in place. We are also planning a range of engagement to alert residents and local path users to the works including a letter to residents of the north Abbey and Fen Ditton area as well as social media and on the ground signage.
"Advance notice signage will be in place from this week (22 July). Signs will include a contact number.
