Parramatta Road could look very different in five years. Sydney’s inner west council today announced a proposal for electric track-free trams (a bus and a tram hybrid) to improve congestion. This comes after more than a dozen plans to improve the artery in the past two decades.

The route, which would run between Strathfield and the city, would be completed within five years in tandem with the West Connex motorway.

The solution was recommended in a study commissioned by the inner west and Canada Bay councils, who also considered alternatives such as light rail and dedicated diesel bus lanes.

While trackless trams are used in several European cities such as Barcelona, Geneva and Luxembourg, it would be the first system of its kind in Australia.
