In a bid to reduce accidents and road rage incidents, Roadways England announced plans to install speed bumps at the eight roundabouts on the A46 Lincoln bypass.
Over the past five years there has been a steady increase in crashes on the roundabouts on the Lincoln bypass and campaigners have been asking Roadways England to come up with the solution.
The authority said it considered reducing the speed limit to 30mph across the bypass but given the constant gridlock, that would not have been an effective measure.
Instead, safety experts advised for speed bumps to be installed at all of the eight roundabouts in a bid to reduce the number of accidents.
Roadways England’s Head of Safety Leonard Miles said: “It’s not the drivers, it’s the roads actually.
“We understand the need to take action to reduce accidents on the Lincoln bypass, and this idea should bring a marked improvement.
“That’s why we will invest over £4 million over the next year to install the speed calming devices at all major entires onto the A46 Lincoln bypass.
“The first to close at night for the installation of the speed bumps will be Carholme roundabout on April 1 for a week, with the other seven roundabouts to follow after that.”
