Redeveloping Main Street Bridge, Blackburn

Council is replacing the bridge at Main Street, Blackburn.

A structural assessment found that the current bridge, which has been in place since at least 1945, is beyond maintenance and needs to be replaced.

The $1.5 million new bridge will be similar in function and design to the existing bridge, with two lanes and a footpath on each side. 

From July 2021 to December 2021, Main Street will be closed to vehicles and pedestrians and the local bus will be diverted while works are underway. 

Plan your trip ahead of time to avoid delay and check alternative routes. Find information below on detours.

November 2021 update

Works are progressing well at Main Street, Blackburn. Demolition of the existing bridge is complete. Concrete beams that will form the new bridge structure have been lowered into place. 

Next steps include:

  • casting the bridge deck and approach slabs 
  • utility service reconnections
  • reinstating the footpath, barriers and asphalt.

We expect the project to be completed in December 2021-January 2022. 


  • Vehicle detours will be in place using the surrounding road network.
  • Some bus service changes will be necessary. Bus commuters will still be able to use Main Street stops. The two bus stops in Main Street between Heath Street and the Avenue will need to be closed.
  • Pedestrians can detour through Furness Park or Kalang Park. Please note: Furness Park is a gravel path with some steep sections. Kalang Park is a gravel path with less steep sections than Furness Park. Pedestrians with mobility issues may need to use the concrete footpaths in Heath Street, Blackburn Road and The Avenue.

There will temporarily be ‘no stopping’ on the north side of Heath Street between Main Street and Blackburn Road.

Previous updates

October 2021 update

The bridge abutments (supports) have been poured and the beams that support the deck of the bridge will be installed in the coming weeks.

The two week COVID-19 shutdown of the construction industry has set back progress on this project. In addition there were delays due to alterations required to underground services. Attempts are being made to recover the lost time, however, it is unlikely that the completion date of December 2021 will be achieved. Further information on the completion date will be provided in November 2021.

September 2021 update

Works are progressing well at Main Street Bridge, Blackburn. Demolition of the existing bridge is almost complete. The next stage is to build the bridge supports. The concrete beams that will form the new bridge structure are currently being manufactured.
