 Although it appears to be an isolated oddity, the road is a reminder of many planned and never built freeways in the Sydney Basin, much like the Gladesville Bridge road complex.The original plans for the Warringah Freeway show the Burnt Bridge Creek Deviation as part of an expressway that would service the growing Northern Beaches area, but it was never built.Suggestions have been floated in recent years to connect the two freeways, with the aid of a tunnel.
