One early problem with Adelaide's streets built in a grid layout was the tendency for motorists to use inner suburb local roads instead of main roads. 'Rat trails' of cars sneaked through narrow sidestreets, creating sizeable bottlenecks. This was a particular problem for Dulwich because of its location - various traffic control methods were put in place (closing streets, speed bumps, lowered speed limits, roundabouts) to counter these problems. This forced the re-routing of traffic onto local thoroughfares such as Fullarton, Greenhill, Kensington and Portrush Roads.
