The Webb Dock Access improvements will better connect freight from Webb Dock to the freeway network. It will make it easier and safer for trucks to enter the Bolte Bridge and free up space and help traffic flow on the M1.

The Webb Dock Access improvements, delivered by the CityLink Tulla Widening project, will support the Port of Melbourne’s $1.6 billion Port Capacity Project.

What are the benefits?

The Webb Dock access improvements will:

  • improve safety on the Bolte Bridge entry ramp, reducing the risk of truck roll-overs and their associated costly delays which can be felt across the freeway network
  • improve traffic flow and safety for motorists and trucks travelling between the West Gate Freeway and the Bolte Bridge
  • provide a quicker and more efficient route for freight that is unaffected by traffic volumes on the M1
  • reduce weaving and merging on the freeway, a major cause of congestion.


Webb Dock Access update – June 2017

Webb Dock Access improvements are in full swing with plenty of major progress.

Bolte Bridge entry ramp

While drivers use the temporary inbound Bolte Bridge entry ramp, crews have been able to excavate a large section of the existing ramp before building the new, redesigned ramp.

A piling rig is working around the clock to install over 1000 piles – approximately 12 metres deep – needed to create a strong foundation for the new, improved ramp to be built upon.

West Gate Freeway

Nearby on the West Gate Freeway, crews are working nights to install the cables and fibres needed to power and supply information to the new digital overhead signage structures and digital displays as part of the state-of-the-art freeway management system we’re installing to create a safer, better flowing and more reliable freeway for drivers.

Cook Street

In Cook Street, crews are busy working nights to relocate the complex variety of utility services in the area. The utilities routed through the area – including gas, power, electricity, water – supply services to thousands of homes and businesses in the Docklands, South Melbourne and Port Melbourne. Crews are working very carefully to ensure that our works don’t cause any disruptions to these vital services.

Crews will be installing a new signalised interchange on Cook Street which will provide a safer, dedicated access onto the West Gate Freeway.


Over the next few months, drivers heading in from the west can expect to see nightly lane closures on the West Gate Freeway. We’ll also be scheduling some overnight inbound Bolte Bridge entry ramp closures to help our crews get the job done as quickly and safely as possible.
