Bridge works could hamper links to a Stirling community for up to 42 weeks.
SNP politicians have raised concerns over Network Rail plans to undertake essential maintenance to the Seaforth Bridge, which links Riverside with the rest of Stirling, from June.
They say the work will cause the bridge to operate with one lane for 10 weeks, be closed to all traffic for 16 weeks, then operate with one lane for a possible further 16 weeks.
Councillor Steven Paterson who represents the area at Stirling Council, said: “This announcement will cause considerable alarm in the community.
“It is essential dialogue begins with locals as soon as possible to update them on what is planned, discuss the contingencies which will be implemented and listen to their views in order to find workable solutions to the inevitable challenges people will face as a result of this work.
“I understand a paper will be brought before a special meeting of the council’s planning and regulation panel next Tuesday which will detail the proposed work. Contingency measures to be recommended include a new temporary pedestrian bridge alongside the current one, to remain for the extent of the work, temporary link roads alongside the railway track to Springkerse Road by the old Players building and another link further along Forthside Way. I am disappointed Network Rail appears to have left it to the last minute to inform the many members of the public whose lives seriously affected by this work.”
Stirling MSP Bruce Crawford said now proposals were on the table, it was important the community were fully involved.
Labour councillor Corrie McChord said: The council has told Network Rail how important it is they fully inform the community of their intentions for the Seaforth Place bridge.
“The SNP ought to know the only reason any work is required is due to their own Scottish Government’s much delayed railway electrification scheme. ”
Network Rail said: “These works are essential for future electrification of the railway to Stirling, Dunblane and Alloa.
“We hope at next week’s meeting to secure agreement to take work forward, then put in place a programme of engagement with communities and stakeholders.”
