There's also an Alan Turing Road in Loughborough but this looks like a new development.
It is a new development.
This is also not a name change, but on the same estate, a short road is named after the double-agent John Cairncross, except it is erroneously spelled "CAINCROSS" instead.
Another honourable mention is that Charnwood Borough Council seem to have no clue how to spell the name Gracedieu. Three roads in Loughborough are named after the Gracedieu Priory, but each are spelled differently: Gracedieu is spelled spelled as a single word on the footpath Gracedieu Way and at one end of Gracedieu Road, but at its other end, Grace-Dieu Road is hyphenated! And finally the dead-end Grace Dieu Court is spelled as two separate words with a space between the two!
On the Garendon Park development on the other side of town, Baily Road was supposed to be spelled without the "E", but the first street sign to be put up (which wound up facing a different street after the temporary connection between Baily Road and another adjacent dead-end street was severed) spelled "BAILEY" instead. This sign has since been replaced, but Google still seems to think it's spelt with an E.
I created a map of streets in Loughborough that have had their names changed (or disappeared altogether). Some highlights include Thorpe Lane between Ashby Road and the former hamlet of Thorpe Acre, parts of which became parts of Epinal Way, Garendon Road and Rupert Brooke Road; Mayfield Drive, which used to have the rather dull-sounding name of Corporation Road; Old Ashby Road, which was - well - the old Ashby Road until Ashby Road was diverted to the south of the then-new council estate; Gladstone Avenue, which used to be just called... The Avenue; and an alley called Dark Hole Lane, which formerly called Dark Hole Street and also at one time partly called Dark Hole Yard and partly Commercial Place. Whatever it was called, Dark Hole Lane disappeared when the extensive premises of the Clemersons department store on the corner of Market Street and the Cattlemarket were demolished in the early 1970s.
And then we have the street names that disappeared only to crop up elsewhere in town. The historical Falcon Street is perpendicular to the original Falcon Street running from Nottingham Road, which ran parallel to the present Morley Street, which used to be further to the south, adjacent to the former mill. Part of Gordon Street became part of the current Falcon Street, with the name resurfacing as Gordon Road as an approach road to an industrial estate (part of which was later realigned when Station Boulevard was built and eventually became part of Station Boulevard). Lastly, Hartington Street formerly ran parallel with the former Falcon Street and the current Morley Street (being situated to the south of both and north of the former Morley Street), which also vanished and reappeared on a new housing estate off Queens Road on the other side of the Grand Union Canal.
