Toothill Road, viewed from Bridge Street
The B589, a short road linking the A6 to the A60 in Loughborough, is out-of-zone (see History, below) but otherwise unremarkable.
It begins on the north side of the town centre, heading east from the point where the southbound A6 TOTSOs right from Bridge Street into Fennel Street. The B589 section of Bridge Street quickly becomes Toothill Road, then later – after intersecting Meadow Road – Clarence Street.
The Meadow Lane crossroads is the only light-controlled junction on the route (turn left here for Stanford on Soar and right for Loughborough town centre). The B589 ends shortly afterwards where it meets the A60 Nottingham Road.
The reason that this route is out-of-zone is that the B589 label has been shifted from its original location to the other side of the A6. This move seems to have occurred at some time around 1980. The first B589 (which, being entirely on the other side of the A6, was in-zone) ran from Ashby Road (the A512) along Broad Street to Derby Road (the A6). Broad Street is now an unclassified road. Today's B589 follows the original route of the A6004, from the A6 to the A60. It is currently unclear whether the two routes of the B589 ever co-existed or if the number was directly moved from one itinerary to the other.
An OpenStreetMap trace for this route awaits uploading to the SABRE Wiki.
