Sixth Line Widening

We’re improving Sixth Line

Sixth Line has been designated a north-south minor arterial roadway in the town's Official Plan (Livable Oakville) and plays a key role in the town’s overall transportation system. 

As development happens along the Sixth Line corridor, the importance of this roadway will increase by providing a critical north-south transportation link. 

The current two-lane, rural cross-section needs upgrading to meet future travel demands and help motorists, cyclists and pedestrians get to work, school, retail and home every day.

Improvements will include the reconstruction of Sixth Line from its current two-lane rural cross-section to an urbanized four-lane road with a centre median and on-road bike lanes, parking lay-by’s and landscaping. 

Phase One 

Dundas Street to Threshing Mill Boulevard

Phase One concrete (curbs, sidewalks, etc.), electrical, storm sewer and landscaping works will be largely complete by the end of June 2023 and final paving will be undertaken in summer 2023.  

Phase Two 

Threshing Mill Boulevard to William Halton Parkway

Phase Two continues with the theme of transforming Sixth Line to a more urban corridor with an expansion from two to four lanes including on-street parking, bike lanes and landscaping.  As of June 2023, hydro pole relocations have been completed and the remaining utility relocation work, including Bell Canada work, is scheduled for completion by the end of August 2023.  

Over the summer, underground work will continue with the installation of a section of the Sixth Line storm trunk sewer from Threshing Mill to approximately 230 metres north. This work will require a full road closure for approximately eight weeks and residents will be advised in advance of the road closure through roadside signage. 

From approximately September 2023 to early 2024, town contractors will vacate Sixth Line to allow for subdivision servicing works.  

Contractors retained by the town are expected to return to Sixth Line to complete the majority of the Sixth Line reconstruction works in the April 2024 to Q1/Q2 2025 period.   

Subdivision servicing within Sixth Line

As Sixth Line is transformed from what was essentially a rural road north of Dundas to an urban corridor, local sanitary sewers and watermains are needed on Sixth Line to provide services to those units that face Sixth Line.  

Installation of these services is expected to occur in stages by various developers over the August 2023 to early 2024 timeframe.  

Full road closures are not expected to be necessary for this work though lane restrictions will be required. This work is not related to the town’s reconstruction of Sixth Line and is needed solely to service the new developments.  All work is fully funded by the respective developments and installed by contractors retained by local developers.
