The project to increase capacity of the junction and refurbish the bridge over the A47/A15 roundabout & junction, known locally as Rhubarb Bridge, started during January 2019 and will run until Winter 2019.
The project is being carried out by Skanska on behalf of Peterborough City Council and will see structural repairs made to the bridge.
As well as the bridge repairs, signalised pedestrian crossings and ground-level footpath across the roundabout will be installed. Upgrades to street lighting and traffic signals at the junction will also be carried out.
The work is being part funded by the Cambridge and Peterborough Combined Authority who carried out a structural survey on the bridges, which confirmed that they could be maintained.
Lane restrictions will be in place during the week which are likely to cause some disruption for motorists. The centre road lane will be closed to traffic, with temporary road markings put down so that the two outside lanes can continue to be used. The restrictions will be lifted at weekends, where it is possible and safe to do so.
