 A pub once stood adjacent to the A316 in Hanworth called the "Brown Bear"; it was demolished in 1973 when the road was made into triple lanes and the flyover with limited access over the junction of Bear/Hanworth Road built.The A316 was the first road in Britain to have stationary traffic enforcement cameras on it, when, on 22 May 1992, then Metropolitan Police traffic officer Roger Reynolds switched on the first such camera, a Gatso, near Twickenham Bridge facing the road westbound.Adjacent to the road in Old Deer Park is a memorial bench to a local girl, Nicola Regan, who died after being run over on this stretch of road in front of a group of friends on 22 March 1991.
