A £2 million scheme is to improve safety at one of the county's busiest and most dangerous junctions.
The large roundabout outside Asda, at Fosse Park – where the A5460 meets Fosse Park Avenue – has been the scene of 42 crashes involving injuries over the past three years.
Leicestershire County Council is planning extra lanes, better pedestrian crossings, cycle links and other measures to make it safer.
The work is to take place over several months, beginning in the school summer holidays with completion expected by November, when the Christmas shopping begins.
Ian Drummond, county council assistant director for transport, said: "This work will improve traffic flow at what is a particularly busy junction, which will continue to get busier as the area grows.
"Not only that, but it will also see important safety improvements made for motorists, cyclists and pedestrians.
"These will in turn, hopefully, reduce the number of accidents at the roundabout."
However, the improvements are set to add more traffic problems to a summer already full of roadworks in the Fosse Park area.
Later this month, gas mains work will take place for about a week over the half-term holiday, affecting the A5460.
Then, during the summer – at the same time as the roundabout work – the Highways Agency will be improving the roundabout under the M1 at junction 21.
Leicestershire County Council said it was too early to give information about the dates of the work, road and lane closures, but said it would be releasing details nearer the time.
Mr Drummond said: "We anticipate it should mean we won't have to make any significant changes to the roundabout for many years to come."
Motorists told the Leicester Mercury their main safety concern was for cars pulling out of Fosse Park Avenue on to the roundabout.
This is not controlled by traffic lights but will be after the work is done.
Nichola Wilkins, 27, of Enderby, said: "I've seen two accidents on that roundabout and both times the drivers have gone out of Fosse Park and into the side of someone else.
"I think more traffic lights might be useful."
Kathleen Longford, 52, of Broughton Astley, said: "It's a very tricky roundabout – confusing and fast, too.
"There do seem to be a lot of roadworks coming, though."
"I'll probably go and shop elsewhere."
Stephen Lawrence, 35, of Hinckley, said: "I've never had a problem with safety but it is a busy roundabout and I don't know how spending £2 million is going to change that."
The work will also include a new signalled junction to allow the western service road traffic to enter the A5460 Narborough Road South more safely.
It will also include an additional lane and signals control on the southern slip road approach with the A5460 link Road.
The county council said it had discussed the project with residents and businesses in the area about the best time of year for the work.
Plans of improvements can be viewed at Braunstone Civic Centre in Kingsway, Enderby Civic Centre in King Street, and at County Hall in Groby Road, Glenfield, until May 15.
