Network Rail has started preliminary work on a new footbridge over the Brayford Wharf rail crossing in Lincoln.
Ground and services investigations are underway and workers are on site.
As previously reported, controversial plans for the new footbridge over the Brayford Wharf level crossing were approved by the Planning Inspectorate in late 2017.
The plans were initially refused by the City of Lincoln Council, whose planning committee felt that the removal of two lift shafts restricted access for disabled people.
Network Rail appealed the decision with the Planning Inspectorate, stating initial designs were “too expensive” and adding that people who cannot use the stairs will still be able to use the crossing as normal.
The adjacent footbridge over the High Street level crossing has lifts with disabled access.
A Network Rail spokesman said: “We’re very pleased to be making progress on the footbridge for Brayford Wharf which will offer a safe route across the railway for pedestrians 24 hours a day, seven days a week with no need to wait at the level crossing barriers.
“We are currently finalising the details of our build programme. We are working to minimise the disruption caused by our work and will share our plans with the community so that they know what to expect as soon as possible.”
