The proposal is for the construction and operation of a one lane eastbound entry ramp from the intersection of Silva Road and Hawkesbury Road that would merge onto the Great Western Highway at Springwood. The proposal would also include the provision of a roundabout, signalised pedestrian crossing and other road safety measures at and near the Silva Road and Hawkesbury Road intersection. The proposal would improve access to the Great Western Highway and improve traffic flow, capacity and safety for motorists and pedestrian along Hawkesbury Road.
