The 10-week road improvement scheme is scheduled to start in early April and will not only improve safety for road users, but will also improve crossing facilities for pedestrians.
Included in the work will be reconfigured lane markings, a signalised pedestrian crossing, the installation of speed activated signs in both directions, a new, high-friction road surface and signage.
Highways England operations and maintenance team leader Nick Reed said:
We have been liaising with our local authority partners and listening to communities to make sure we have the right junction layout in place for this scheme.
We have looked at all of the available safety measures for this junction and we are now in a position to start the safety improvement scheme.
Traffic management will be in place during the work, we will be working to keep disruption to a minimum and further details will be available in due course.
The safety improvement scheme is expected to cost around £560,000 and is due to be completed in mid-June, in time for the summer holidays.
