Blackspot Program

Between Millers Road and Melbourne Road, in Altona North and Newport Council has been successful in obtaining funding for $1,799,000 under the Federally Funded Blackspot Program, to deliver infrastructure improvements on Mason Street that will help improve safety outcomes.

Council has created a concept plan for these infrastructure improvements and is seeking feedback on this plan, before the project progresses into detailed design. You can view the concept plan here or in the document library to the right of this page.

Mason Street, Newport

A high number of accidents has been identified along Mason Street, with a total of 33 accidents in the last five years, including one fatal, 10 serious and 22 other injury accidents. 10 out of 33 accidents were cyclist-related.

Mason Street is an east to west route which connects Millers Road to the west and Melbourne Road to the east. Mason Street has a two way traffic volume of 16,000 vehicles per day and has a posted speed limit of 60km/hr for the majority of its length, reducing down to 40km/hr east of Williams Street on the approach to the commercial centre. There is also an existing 40km/hr school speed zone located between Seventh Avenue and Second Avenue.

Mason Street is part of the principal bicycle network, however, at the roundabouts, cyclists are required to merge into traffic and cycle through the roundabout. Bus routes 432, 471 and 944 night bus services also operate along Mason Street.

What traffic changes are included in the concept plan?

The proposed scope of work is as follows:

  • upgrade of existing school crossing on Mason Street between Fourth and Third Avenue to a zebra pedestrian crossing with Flashing lights for improved pedestrian safety.
  • reduction of the speed limit on Mason Street from 60km/hr to 50km/hr between Millers Road and William Street
  • installation of electronic 40km/hr speed signs on Mason Street through the Newport shopping precinct
  • construction of new C Roundabout at the Fifth Avenue and Mason Street intersection, and modification of existing roundabouts at the following intersections:
    • McIntosh Road and Mason Street
    • Blenheim Road and Mason Street
    • Mason Street and Maddox Road
  • construction of two raised pedestrian crossings on McIntosh Road near the Mason Street intersection

The proposed traffic treatment map below details the locations and treatments proposed along Mason Street, Newport.


What are the benefits of the proposed traffic changes?

The concept plan seeks to introduce road safety treatments that will address the issues along Mason Street and reduce the likelihood and severity of crashed occurring.

The proposed C-roundabouts will create an irregular central island to slow down vehicles as they manoeuvre through the island and the reduction in the speed limit will reduce the severity of crashes as they occur. The plan also aims to promote cycling as an alternate mode of transport by provide safer bicycle facilities along Mason Street and importantly improve pedestrian safety.

What are C Roundabouts?

The C-Roundabout is a modified roundabout design that consists of a central island of an irregular shape. The implementation of C Roundabouts will result in reduced speeds at these key intersections providing increased safety to pedestrians and cyclists. Research shows that this type of roundabout significantly decreases the change of a fatality occurring.
