The Pytchley Road railway bridge has been demolished and partly rebuilt over the Christmas period.
The old bridge was taken down during overnight work between Christmas Eve and Friday, December 27.
Network Rail says the bridge work is an essential part of the electrification work on the Midland Mainline and is part of a £70m modernisation project.
Hydraulic equipment, called breakers, was used to demolish the old bridge on Christmas Eve. New arches were then constructed.
Some of the original bridge is still visible near the railway line.
A spokesman for Network Rail said Pytchley Road is likely to re-open on February 28.
Two weeks ago, the Telegraph spoke to a couple living near the Pytchley Road bridge who said they were being kept awake at night at the weekends because of the project’s overnight schedule.
At the time, Network Rail said the work needed to be carried out overnight as this was the time when trains weren’t running.
