Lydiate Ash – Stourbridge Starting at junction 4 of the M5, the road heads West on a single carriageway alignment, meeting the B4091 at a roundabout, then becoming a dual carriageway. There are local accesses for the villages of
Belbroughton,
Clent,
Romsley and
Holy Cross. Following a roundabout in
Hagley the A491 is concurrent with the
A456 for a short period before heading north towards
Stourbridge. At
Pedmore the
A4036 leaves at a roundabout towards
Dudley. The former northern section of the A450 (now B4187) from Worcester joins from the left. The A491 then continues to join the Stourbridge ring road. The one-way ring road forms part of the A491 and is concurrent with the A458 and forms the starting point of the A451 to Kidderminster.
Stourbridge – Wall Heath The original route of the A491 resumes on the northern side of the Stourbridge ring road. This final section is entirely single carriageway, apart from a short distance between the staggered junction with the
A461, in an urban environment causing major delays. The road passes through
Amblecote,
Wordsley and
Kingswinford, passing numerous traffic light controlled junctions including those with the
A4101 and
B4175, before terminating on the
A449 at a roundabout just north of
Wall Heath. ==Former routes==
