9 July 2026

The Cranbourne and Pakenham lines are boom gate free and trains are running through the Metro Tunnel. We’re continuing construction of the new road under the rail line, connecting Princes Highway-Lonsdale Street to Cheltenham and Hammond roads. The new road underpass will open in spring – 2 years ahead of schedule.

What we’re doing

We’re continuing to build the new road underpass, installing kerbs on Cheltenham Road and Princes Highway-Lonsdale Street and undertaking works on the speed hump on Webster Street in July.

To safely complete works, we’ll close lanes and pedestrian paths along sections of sections of Cheltenham Road and Princes Highway–Lonsdale Street. We’ll also temporarily close Webster Street between Ellis Street and William Avenue.

What to expect

  • Lane closures overnight from 8pm to 6am and during the day from 9am to 3pm
  • At all other times we’ll work from 7am to 6pm, Monday to Friday and 7am to 3pm, Saturdays
  • Road and lane closures with detours and traffic management in place
  • Increased noise, vibration, vehicles and workers in the area. Water carts and street sweepers will be used to minimise dust.

Properties impacted by these works will be contacted directly. Access will be maintained for residents, businesses and emergency services.

We’ll make every effort to complete works on schedule; however, dates and times are subject to change.
