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 are the first works to commence on the Western Distributor project and will support the Port of Melbourne’s $1.6 billion Port Capacity Project. The CityLink Tulla Widening project will deliver these works on behalf of the Western Distributor project.

These improvements complement the upgrade of Cook Street currently being completed by VicRoads. These works are widening Cook Street from one to two lanes in each direction between Todd Road and the West Gate Freeway.

What's involved

    An additional lane will be added in each direction between Todd Road and the West Gate Freeway

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.


February 2017

Construction to improve access to Webb Dock  is in full swing with crews working day and night in the lead up to kicking off our next major stage of works.

Webb Dock update - Feb 2017

With the existing roundabout at Cook Street/Salmon Street removed and works to widen a section of Cook Street underway– between Gateway Court and Salmon Street activities are now focused on the West Gate Freeway.

West Gate Freeway traffic heading towards the CBD will have noticed plenty of change taking place along the left hand side of the road between Cook Street and the Bolte Bridge.

Crews are hard at work building a new inbound separated road next to the freeway that will provide motorists and trucks safer, dedicated access to the Bolte Bridge entry ramp from Cook Street.

Nearby, crews are building a temporary ramp ahead of major works to build a new, redesigned Bolte Bridge entry ramp.


In the next few months, inbound West Gate Freeway traffic wanting to access the Bolte Bridge moved over to the temporary ramp while crews demolish and rebuild a new permanent ramp that will make it easier and safer for cars and trucks to merge onto the bridge.

Over the next few months’ drivers can expect regular overnight freeway, ramp and lanes closures as crews work towards wrapping up these works in mid-2017.
