Buses will replace trains on the Werribee line tomorrow for the next week as crews work to remove three dangerous and congested level crossings.
Buses will replace trains between Laverton and Werribee from the first train Friday, 7 August until the last train Thursday, 13 August.
Passengers who must travel for one of the permitted reasons are asked to allow an extra 25 minutes travel time.
On the roads, Werribee Street, Werribee will be closed at the level crossing between Cottrell Street and Princes Highway from 8pm Thursday, 6 August to 3am Friday, 14 August.
Motorists conducting essential travel can detour via Bulban Road, Galvin Road, Browns Road, Alfred Road, Nattarak Avenue, Tindale Boulevard and Princes Highway.
On Cherry Street, one lane of traffic will be open in each direction and speeds reduced near the level crossing.
The inbound exit from the Princes Freeway to the Princes Highway, Hoppers Crossing (C109) has closed long-term. Motorists can use the earlier Sneydes Road exit.
In normal times nearly 60,000 vehicles use the level crossings at Cherry Street and Werribee Street in Werribee, and Old Geelong Road in Hoppers Crossing each day. The three crossings will be gone for good by 2022.
When the bridge is completed in 2022, a new interchange will connect the Princes Freeway to the Princes Highway, Old Geelong Road and Heaths Road.
