So far, 32 pairs of wheel timbers have been replaced and works are on track to be completed by the end of November.
Speed restrictions are currently in place to make it safe for trains passing over these bridges. Network Rail is carrying out regular inspections to monitor the safety of the bridges, with additional measures and further speed restrictions able to be implemented if necessary.
The remaining weekends of work are on the following dates:
- Sunday October 25
- Saturday October 31 and Sunday November 1
- Saturday November 7 and Sunday November 8
- Sunday November 22
- Sunday November 29
Passengers planning to travel on the route from Ely to Peterborough on these dates are urged to check with their train operator before setting off for their journey.
Ellie Burrows, Network Rail’s route director for Anglia, said: "A huge amount of progress has already been made as our engineers work hard to renew the wheel timbers across the four structures.
"Running a safe railway is my absolute priority and this work is vital to keep our network running safely and smoothly while reducing the risk of delays. I’d like to thank our passengers for their continued patience while we complete our work."
Jamie Burles, Greater Anglia managing director, said: "It’s good to hear that this work is going well. We will continue to make sure passengers can complete their journeys – even if part of it is by bus. We have enough buses so that people can socially distance.
"Please remember to wear a face covering on our stations, trains and the rail replacement bus service."
