From this area the circuit headed south to cross the southern portion of Birmingham's ring road, the A4540 road, before it turned left and then headed east on a minor collector road. After approximately 180 metres cars took the southern part of the Belgrave Interchange roundabout as a right-left-right chicane, before following the slip road to drop down on to the south side (normally westbound lane) of the A4540 Belgrave Middleway dual carriageway. This continued as an undulating and slightly curved straight for around 650 metres until the cars arrived at the Haden Circus roundabout, named Halfords Corner after the title sponsor. Here, a large proportion of the centre of the roundabout island had been flattened and surfaced with tarmac forming a broad pan, reducing the radius of the hairpin corner significantly, but the slightly dished profile of the roundabout itself remained resulting in a significant hump as cars entered the corner's braking zone.
