After Selly Oak, the A38 takes the Bristol Road into the city as far as the Belgrave Interchange with the A4540 Middleway ring road. The city centre section takes a novel line, laid out as part of extensive reconstruction works in the 1960s, and is one of the few remaining pieces of the original "concrete collar" inner ring road. Thanks to being mostly underground, travelling through an underpass at Holloway Head and the two Queensway tunnels at Paradise Circus and Snow Hill, plus a flyover at Lancaster Circus, the A38 is able to travel straight through the city centre uninterrupted, eventually meeting, at a final underpass beneath Dartmouth Circus, the A38(M) Aston Expressway. The old road took a largely similar line as far as what is now Paradise Circus, before zig-zagging in a less direct and much slower route through the city centre, taking in the north side of New Street Station and then travelling along Corporation street to briefly rejoin its modern alignment.
