 It then goes under another railway bridge by Tolworth railway station before crossing the A3 at the Tolworth Junction, a grade separated roundabout, which the A3 takes uninterrupted.In rush hour, traffic jams from Tolworth junction can stretch to the junction with Thorndon Gardens.Now as a non-primary road and a single carriageway road again, the A240 continues north-west as commercial Tolworth Broadway passing a well-known landmark, Tolworth Tower, before becoming longer Ewell Road which gently ascends from 24 to 32m where it crosses the South Western Main Line northeast of Surbiton railway station.
