The section of the A45 from Birmingham city centre to the M45 is all dual-carriageway.
The former route of the A45 through Coventry exits at a junction as the A4114, in the part of Coventry called Allesley, the western end of the Coventry bypass.
The route bypasses Ringstead and the A45 finishes at a GSJ with the A14 near Thrapston.
The city council, working with Travel West Midlands and Centro, is considering improvements along the A45 Coventry Road through Digbeth and Deritend, along the Small Heath Highway and Coventry Road to the Solihull boundary.
The A45 Coventry Road is an important route for road users and pedestrians, and a major bus route between Birmingham and Solihull.
The improvements, which are intended to benefit pedestrians, cyclists, bus users and motorists, will follow the route of the 58 and 60 bus services.
