Key features

Package 1a 

Early works commenced in January 2022 and included relocation and protection of major water mains and telecommunication networks. This work was completed in early 2023. Two gas main relocations started in October 2023 and were completed in February 2024.

Package 1b (current construction works)

• New southbound flyover on the Monaro Highway over Lanyon Drive (including three-metre wide sealed shoulders). The new bridge structure will have indigenous artwork applied to some of the external materials.
• Upgrading of the highway road pavement from David Warren Road through to Sheppard Street (including three metre wide sealed shoulders).
• New widened bridge on the northbound carriageway over Dog Trap Creek/Woden Creek just north of Lanyon Drive.

Package 1c 

• Roundabout at the intersection of the new Monaro Highway southbound off-ramp and David Warren Road extension.
• Upgrading the signalised intersection at Lanyon Drive and Sheppard Street to four ways to include a direct connection to David Warren Road and the southbound off-ramp.
• Removal of traffic lights at the Alexander Maconochie Centre intersection (David Warren Road).

In addition to the above, a new shared path is being designed as part of the Monaro Highway Upgrade Project. This design will identify the path’s alignment for delivery as part of future stages. Earthworks along the path alignment will be delivered during construction of the Lanyon Drive Interchange to support this future connection in the path network as part of the Active Travel Plan.

Current update

Construction activities began on site in January 2024. The next major package of construction work, following the now complete utility works, includes:

• new southbound flyover on the Monaro Highway over Lanyon Drive (including three-metre wide sealed shoulders)
• upgrading of the highway road pavement from David Warren Road through to Sheppard Street (including three metre wide sealed shoulders)
• new widened bridge on the northbound carriageway over Dog Trap Creek just north of Lanyon Drive.

Initial works on site include significant ground clearing and earthworks with heavy machinery including excavators and trucks moving around the site.

Temporary traffic management

Reduced speed limits will be place for the duration of the work. This will generally be 60km/h on both highway carriageways while work is underway. Temporary lane closures and speed reductions to 40 km/h will intermittently be in place outside peak periods.

The changed speed limit is required for several reasons including each of the below.

• The project site is a very restricted work area due to the existing carriageway and available median and verge areas; this means works will be carried out in close proximity to the existing roadway and road users.
• Temporary concrete safety barriers adjacent to travel lanes, reduced lane and shoulder widths, and temporary traffic diversions are required to accommodate the works safely.

Whilst every effort is made to minimise disruption throughout construction, including maintaining traffic lanes where possible, there are expected to be travel time impacts during the project. We encourage everyone to think about how they travel and whether you are able to travel outside of peak periods.

Possible features

• New flyover on the Monaro Highway connecting Mugga Lane and Tralee Street in Hume.
• Modification of the existing Monaro Highway/Sheppard Street intersection to allow left-in/left-out only movements to and from the Hume Industrial Precinct
• Upgraded roundabout at Mugga Lane and associated lanes approaching the new Hume flyover as well as on-ramp access to the Monaro Highway northbound carriageway.
• Upgrades to local streets and intersections within the Hume industrial precinct including the Tralee Street approach to the Monaro Highway and the intersection of Tralee Street and Sheppard Street.

Possible features

• New flyover on the Monaro Highway over the Isabella Drive extension.
• Extension of Isabella Drive from the existing Monaro Highway roundabout, including a new roundabout connecting to Tralee Street south.
• Monaro Highway southbound off-ramp and associated lanes connecting to the Isabella Drive extension.
• New lanes running parallel with the Monaro Highway northbound carriageway between Isabella Drive and Mugga Lane to facilitate traffic entering and exiting Monaro Highway.

Current update

Preliminary design work is continuing for the Isabella Drive and Hume interchanges. This will inform possible future projects at these locations, subject to future government consideration. As part of this design phase we will be engaging with local businesses in the Hume industrial precinct. If you are a business owner or tenant, we encourage you to get in touch with the project team via email at communityengagement@act.gov.au.

A National Capital Plan amendment is being undertaken for the second package of works encompassing the Isabella Drive interchange and the Hume interchange. The amendment is required to adjust the designated area boundary to account for the updated alignment of the Monaro Highway including its widening and the two new interchanges which will subsequently result in a revised road reserve.

A successful amendment will streamline statutory approvals with the majority of works covered by one planning approval through the NCA for the Monaro Highway Upgrade (MHU) Package 2 – Isabella Drive and Hume Interchange. This amendment is necessary ahead of progressing further design work on both interchanges and to allow for planning approvals to be submitted.

Consultation on the draft amendment commenced Saturday 11 November and closed Friday 8 December 2023. It is currently under assessment. For more details on the draft amendment visit the NCA website.
