As a result, the estimated cost of the route to Anglesea Road and then around to Princes Highway West is $618 million - about $200 million more than Option 3 plus a connection to Anglesea Road would have cost. In addition the fact that the route is 3 km longer than Option 1, that most freight traffic comes from the west, and the route requires trucks to negotiate slopes down into the Waurn Ponds Valley and then back out again means the additional cost to users is around $10 million per annum. Finally around 360 households are located within 160 metres of the Ring Road and subject to noise and diesel engine particulate matter pollution whereas with the Option 3 route only 10 houses would have been within 160 metres.
