Thompson Road and Mornington Peninsula Freeway Interchange Upgrade

Overview

We’re planning for an upgrade to the western side of the Thompson Road and Mornington Peninsula Freeway interchange, in Patterson Lakes.

The upgrade aims to improve safety and traffic flow.

Planning and development

Planning work is underway and key activities include:

• developing a design
• detailed traffic analysis and modelling, to better understand the future growth of the area and the demand this will place on the road network
• environmental investigations to understand flora, fauna and tree species
• investigations to map utility services.

We expect our initial planning work will be complete in 2026. Construction timelines will be known once our planning has progressed further.

Site investigations

To help inform our planning, we’ll complete site investigations. At times, we may need to implement traffic control measures, including temporary lane closures, stop/slow traffic and reduced speeds. We’ll keep traffic disruption to a minimum and avoid busy periods.
