A46 Coventry junctions upgrade
The A46 is a strategic road link between the East and West Midlands, connecting Coventry and Warwickshire to the motorway network. Traffic congestion has led to slower speeds, longer trip times and more queueing for drivers. By upgrading the A46 we’ll unlock this congestion, improve journey reliability and support economic growth across the West Midlands.
We’re investing in the A46 at Coventry by upgrading two junctions to:
- improve safety
- increase road capacity
- relieve traffic congestion
- smooth the flow of traffic
- support the growing economy
The upgrade is being delivered in two phases.
Work at the Binley junction started in March 2020 and was completed in February 2023.
From 25 October to 6 December 2023, we're consulting on our plans to upgrade the Walsgrave junction. To find more about our proposed scheme, view our online consultation brochure here.
The Coventry junctions (Walsgrave) scheme is part of our commitment to improve the A46 ‘Trans-Midlands Trade Corridor’ between the M5 and the Humber Ports.
The Coventry junctions scheme involves the upgrade of two at-grade junctions (Binley and Walsgrave) to provide relief from traffic congestion and to improve journey times by increasing the capacity on the A46 between the M6 and the M40. This will benefit both the strategic and local traffic needs and support future growth forecasts from Coventry City Council.
Walsgrave junction is the last remaining roundabout east of Coventry and north of Tollbar End junction that is at-grade, and as such it is a pinch point for traffic. The Tollbar End junction and M6 Smart Motorway improvements have increased the pressure on Binley and Walsgrave junctions.
The A46 Binley junction improvement scheme was opened to traffic in November 2022, converting the junction from an at-grade signalised roundabout to a grade separated junction. There are concerns that without further investment to reduce congestion on the A46, the benefits of the improvement works at Tollbar End junction would be limited. In particular, the current delays at the Walsgrave junction could undermine the existing investment which has been made on the A46 improvements.
Our current project timeline is shown in this diagram:
The aims of the scheme are to:
- improve safety
- support the growing economy
- support the smooth flow of traffic
- increase capacity
- relieve congestion
A46 Coventry junctions (Walsgrave): Preferred route fly through video - visual description
This visualisation has been created to provide a preview of the proposed scheme layout. The features shown are for consultation purposes only and may change as the design develops.
Our proposed design
The A46 Coventry junctions (Walsgrave) scheme aims to realign the existing A46 dual carriageway through the existing junction, for a length of approximately 880m with a 50mph speed limit.
We’ll realign the B4082 link road single carriageway with a 40mph speed limit running parallel to the A46 for approximately 910m connecting into the proposed dumbbell junction.
We’ll also create a new junction which consists of two new roundabouts connected via a new bridge over the A46.
We’re proposing to realign the A46 to provide a continuous dual carriageway through the existing Walsgrave junction.
The majority of the scheme will be at existing road level. Starting from Brinklow Road, the first 300m of the A46 will be at the existing road level before gradually rising to a maximum of 0.7m above the existing road and then returning to existing road level at Hungerley Hall Farm access bridge. The raised section is due to the existing road level being higher and meets design standards.
Due to the curvature of the new road, the speed limit through the A46 Walsgrave junction would be reduced to 50mph to meet design standards.
The B4082 link road will remain as a two-lane single carriageway on the existing alignment towards the proposed Walsgrave junction for approximately 245m.
A new section would be created, taking the road north towards the proposed Walsgrave junction.
The road would be in a cutting (below existing ground level) between Hungerley Hall Farm and the A46 before it rises on an embankment (above existing ground level) to meet the new junction. This would provide access from the local road network onto the A46 northbound and southbound.
We propose reducing the speed limit on the B4082 to 40mph to meet design standards.
Existing junction and lay-bys
The existing Walsgrave roundabout and two existing lay-bys will be removed and replaced with landscaping.
The proposed new junction connects the local road network via the realigned B4082 to the A46 northbound and southbound.
The junction is made up of a western and eastern roundabout connected by a new bridge that crosses over the A46 at approximately 9m above the existing road level. We’re looking to reduce the height of the bridge as the design develops.
The western roundabout has been designed to accommodate a future access route for emergency services vehicles to the University Hospital, which would be delivered by others in the future and does not form part of this scheme.
Three drainage features, known as attenuation basins, are proposed. These will contain surface run off before discharging to the River Sowe.
The drainage features will be located off the B4082 near the existing Hungerley Hall Farm access road, between the new section of the B4082 and A46 and to the north of the proposed western roundabout.
There is a National Grid overhead line to the west of the A46 and over the existing B4082. We don’t anticipate any impact on the overhead line and we’ll work with National Grid to ensure we allow enough working space.
