We’re building a new Grimshaw Street interchange
The upgraded interchange will see through traffic pass under Grimshaw Street, with dedicated lanes kept for local trips. A bus priority lane will improve public transport travel times. Two new underpasses will create safer journeys for pedestrians and cyclists. We’ve also created more space for trees and plants.
A new, wider Nell Street walking and cycling bridge will create better east-west connections for locals. In response to community feedback, we’ve moved the bridge further south for a shorter, more direct crossing.
There will be improved green spaces for Trist Street Reserve and AK Lines Reserve with upgraded with new wetlands, indigenous trees and plants, walking and cycling paths, noise walls and seats.
What’s coming up?
We’re getting Grimshaw Street ready for major construction of the new interchange later this year, including building retaining walls, relocating utility services and preparing ramps.
During September 2025, there will be intermittent day and night traffic changes, including lane and road closures, on Grimshaw Street and local streets to conduct utility and bridge works.
In October, Grimshaw Street will be closed in both directions between Greensborough Bypass and William/Adeline streets, as we begin major works to construct the new Grimshaw Street interchange. During works, we’ll build the eastern foundations for the Grimshaw Street road bridge, a new walking and cycling underpass and new gantries over the road. Buses will replace trains on the Hurstbridge Line during works.
From early November to mid-December, Grimshaw Street will be closed in both directions between Macorna Street/Watsonia Road and Greensborough Bypass. During works, we’ll build the western foundations for the new Grimshaw Street road bridge, and the new walking and cycling underpass between AK Lines and Trist Street reserves.
Keeping in touch
We regularly speak to nearby residents and businesses about these works in more detail, including how we’ll be managing any local impacts.
