The improvements to M5 Junction 10 will increase the capacity of the junction and upgrade it to an all movements junction. Four new slip roads will replace the existing two slip roads, and two new single span overbridges will replace the existing Piffs Elm Interchange Bridge which will be demolished. A new elongated roundabout will be created using the two new overbridges.
Signage and technology equipment will be installed along the M5 to the north and south of the junction. The A4019 will be realigned to join the roundabout at an appropriate angle. The new roundabout, and approaches to it, will be lit. The speed limit of the A4019 across the roundabout will be 50mph. The national speed limit for motorways will apply on the motorway slip roads.
The existing Leigh Brook culvert (under the M5) will be extended to run beneath the new slip roads. The River Chelt culvert (under the M5) will be retained and will not need to be extended. River banks for both Leigh Brook and the River Chelt in the environs of the culverts will be reprofiled and planted to improve habitat and biodiversity.
A dedicated route for cyclists and pedestrians will be provided through the junction. A new access track to the northeast of the M5 Junction 10 will replace the existing access points to field areas and to the informal Traveller site. The existing public footpath (ABO14) west of the M5 and south of the A4019 will be rerouted to ensure connectivity. The existing public footpath (ABO16 part 2) through the River Chelt culvert will be retained.
Highway drainage from the new slip roads and roundabout will be to two new attenuation basins to
the west of the M5, north and south of the junction. To the southeast of the M5 Junction 10, an area of land will be reprofiled by excavation of material, to provide flood storage for the Scheme, and compensation for the loss of flood storage from the construction of the Scheme. The land around this excavated area will be designed to provide a mix of habitats.
An underpass will be constructed immediately to the east of M5 Junction 10, to provide a traffic free route for pedestrians, cyclists, horse riders and bats to pass under the A4019.
