 Infill development within this area continued in the late 1860s with Hastings Road and Franklin Road, followed in the early 1870s by Agnes Street, Franklin Street, De Montfort Road, Fairlight Place and St Martin's Place.Meanwhile, the Kemp Town branch line had opened in 1869, forming the eastern limit of the residential area until 1880 when Bonchurch Road, Brading Road and Totland Road were built further up the hill on a north–south alignment parallel with the line.Newmarket Road, Upper Wellington Road and Normanton Street filled in more gaps in the meantime, and Elm Grove itself was continuously built up as far as Totland Road by 1884.
