Work to build a flyover at a notoriously busy roundabout in Little Eaton has been brought forward by two years.
Currently motorists face an average peak time delay of 16 minutes at Abbey Hill roundabout, with queues stretching around 2.6 miles.
The problem has affected commuters for more than 30 years - since the A38 was first built and the Government ran out of money to complete that part of the work.
Now it has been announced that a flyover will be built at the roundabout in 2016 - two years earlier than was originally planned.
The plans were announced as part of a £175 million scheme unveiled by Chief Secretary to the Treasury Danny Alexander which will also see flyovers at Kingsway and Markeaton roundabouts.
Belper MP, Pauline Latham said she had been campaigning “very hard” for the road improvements for many years.
“This is exceptionally good news for Derby and Derbyshire,” she said.
“I am pleased that the Government and in particular the Transport Secretary and fellow Derbyshire MP, The Rt Hon Patrick McLoughlin, has really listened to me campaigning and lobbying on this issue.”
