|Junctions related to the B4110|
Tollbar End is a grade separated junction between the A45, A46 and B4110 on the eastern end of the Coventry Bypass. 90,000 vehicles a day use the junction, which prior to its upgrade between 2013 and 2016 caused significant congestion on most approaches.
Before the Coventry Bypass was constructed in the 1920s, there would have been no significant junction at this site. Once the A45 was diverted to the south of Coventry, the A423 took the former route of the A45 into the city centre. The junction would have then remained relatively unchanged until the 1990s when the Coventry Eastern Bypass was constructed as part of the A46, which plugs into the northern side of the roundabout.

A £106 million scheme to enlarge the roundabout and build an underpass between the A45 and A46 arms was completed in 2017. The scheme includes widening of the A45 Stonebridge Highway between this junction and Stivichall Interchange to D3, which opened to traffic in early 2016. The underpass was opened to traffic in November 2016, while work on the roundabout was completed a few months later.
The grade separation of Tollbar End was first proposed in 1998 as part of 'A New Deal For Trunk Roads', while it entered a targeted programme of improvements. It wasn't until August 2013 that work commenced on the project, following several consultations, exhibitions and modifications to existing plans.
Previous upgrade proposals
Proposals to grade separate the junction date from as far back as the 1960s with firm plans being made by the 1970s. However the main traffic flow would have been far different from today's. The Eastern Bypass would have been a urban distributor serving the north and east suburbs of the city eventually dumping its traffic on the North-South Motorway at Rowley's Green. It wouldn't have been a major trunk road connecting to the M69. As a result the flyover favours the A45. The roundabout itself would have moved slightly westwards and the former protected line for the Eastern Bypass is now the retail park access road.
