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 been done
We’ve finished the 30-day rail and road blitz at Grimshaw Street east ahead of schedule, opening the road to traffic in the early hours on Thursday 30 October.
Whilst Grimshaw Street was closed between Greensborough Highway and William/Adeline Streets, we demolished and reconstructed the road bridge over the Hurstbridge rail line, installing 67 bridge beams weighing up to 22 tonnes each.
Crews also installed noise walls, constructed bridge abutments and completed the rail tunnel extension under Greensborough Highway, installing 118 beams for the rail tunnel roof, each measuring up to 17 metres long.
We thank you for your patience during this time and please remember to drive safely in the area.
What’s coming up?
From 9pm, Friday 7 November to mid December, Grimshaw Street will be closed on the other side of Greensborough Highway, in sections between Watsonia Road/Macorna Street and Greensborough Bypass.
Across November and December 2025, we’ll build the western foundations for the new Grimshaw Street road bridge. We’ll also build the new walking and cycling underpass between AK Lines and Trist Street reserves.
It’s all part of building the new road connections and dedicated lanes that’ll connect the completed M80 Ring Road to the North East Link tunnels – keeping local roads for local trips.
The completed M80 Ring Road will take 19,000 cars and trucks a day off Greensborough Road, with traffic passing under Grimshaw Street, Elder Street and Watsonia Road – keeping local roads for local trips.
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.
