 The largely straight road from Hampton Court was surfaced and tolled in the 1780s by the Hampton and Staines Turnpike Trust.In the west its buildings were set back with gardens and therefore it was widened in Spelthorne in the 1920s.As Staines Road East, the A308 winds past Kempton Park Racecourse, Sunbury-on-Thames and adopts instead of south-west followed after Kingston by west, the direction WNW, allowing it to meet Junction 1 of the M3/the A316 at the Sunbury Cross area also within Sunbury on Thames.
