Alphington residents, angry that a new six-lane bridge will be built metres from their homes, confronted Andrews government ministers as they announced the project at a press conference on Wednesday.

Roads Minister Luke Donnellan and Fiona Richardson, Labor member for Northcote and the Minister for Women, spent several minutes defending the government's decision to put the planned $110 million bridge on the western side of the existing, heritage-listed Chandler Highway Bridge.

Mr Donnellan could not say how many metres from homes the new six-lane road would be, but said its surface would use a quieter bitumen to reduce traffic noise.

A western alignment has been selected in favour of the eastern side of the 124-year-old bridge, where the old Amcor paper mill is to be developed into a housing development with about 2500 properties.
