|Route outline (key)|
Eastville - Nailsworth
The road starts on the A432 in Eastville, northeast of Bristol City Centre, and almost immediately meets the M32 at junction 2. After flirting with the motorway at this junction the road then runs parallel to the east of the M32 before crossing the A4174. After meeting the B4427 it goes under the M4 (without a junction) to go through Winterbourne. It gradually leaves the urban sprawl of Bristol and is briefly the dominant partner in a multiplex with the B4059 around Iron Acton. At the end of the multiplex it TOTSOs left into a more rural section via Chartfield up to Wotton under Edge, where there is a brief multiplex along the B4060.
At the top of Bear Street both roads TOTSO. The B4058 turns right then left at a roundabout before leaving town. After this, the road winds its way up Coombe Hill and then climbs further into the Cotswolds, meeting the A4135 at the top, which it briefly multiplexes with. The last section runs gently downhill across countryside into Horsley before descending to meet the A46 in the centre of Nailsworth.
Originally, the B4058 only ran as far as the B4060 at Wotton under Edge. The remainder of the route was the B4063 as far as Symonds Hall and then unclassified. The current route dates from the 1935 Road numbering revision.
