 A request from the Midland Railway to convert bridges over the canal into embankments was denied by the proprietors, on the basis that they did not have to authority to grant it.The railway bridge at West Hallam was rebuilt in the 1950s, although that at Derby Road was partly filled in at the same time.The road bridge at New Stanton was lowered in 1913 by the Ironworks Company, who attempted to get Shardlow Rural District Council to contribute to the cost, but there is no known record of the outcome.
