The A6117 is listed in the DfT Card Index as Melton Mowbray (Wilton Road).
The road was a short link on the western side of the town centre. It started to the north of Leicester Bridge where the A607 turned right into the High Street. The A6117 continued north along Wilton Road to end on the A606 Park Road and B679 Asfordby Road.
Owing to the short length of the road and the fact its number does not appear on any known maps determining the history of the route is difficult. OS Maps from the early 1930s don't show Wilton Road, suggesting that it was built in the mid 1930s, and that there must therefore have been an earlier incarnation of the A6117. Later maps continue to give the road Class I status - although it is just as likely that the road had been renumbered as a spur than it was still the A6117. Either way the A606 has now been diverted away from the town centre along the entire length of the ex-A6117.
