The A6133 route in Newark provided a slightly more direct link from the A17 to the southbound A46, albeit zig-zagging through the town centre so it is doubtful if it was actually a quicker route. Forking off the A17 immediately to the west of the railway bridge, the A6133 continued to follow Beacon Hill Road into town (this was the original line of the A17), before turning left onto Friary Street and then sharp right onto Barnby Gate. A final right turn led down Carter Gate, and so to the routes terminus on the A46 at Beaumond Cross.
The route described above is as identified from mapping in the later 1960s, after the A1 had been diverted onto the Bypass. However, this would mean that it was out of zone, when the A1 still ran through Newark. As such, it can be presumed that the A6133 continued south from Beaumond Cross on what was to become a spur of the A46, along Portland Street and Victoria Street to meet the A46 to the south. This was formerly the B689 and is now part of the B6166. At present, however, there is no mapping evidence for this.
