Looking west from the Ninth Line overpass in western Mississauga. Just west of Ninth Line, the mainline Highway 407 lanes cross overtop of the 401. Considering the complexity of the 401/407 interchange, it is quite surprising that is has but a two-levels.

Highway 401 looking west from the Mississauga Road overpass. Mississauga Road is located at kilometre marker 336. The Mississauga Road overpass and interchange were reconstructed in the early 2000s in advance of the extension of the core-distributor system extension west of Highway 410. The upper photos show Highway 401 prior to the extension of the collector lanes through western Mississauga, while the lower two photos highlight the widened segment of highway.

Highway 401 looking east from the Second Line West overpass towards the Mavis Road interchange. The Mavis Road interchange was completed in late 1999. The Mavis Road overpass was designed so that the abutments can be removed, allowing the structure to be elongated to support a C/D underneath the overpass.

This view looks westerly towards the Second Line overpass. The Second Line overpass will be demolished in coming years to make way for a highway widening project. This four span arch bridge looks to be in ailing condition as crews have completed various concrete patches to repair spalling concrete in lieu of a full scale rehabilitation.

Looking westerly towards the Mavis Road interchange from the McLaughlin Road overpass. The McLaughlin Road overpass will be replaced during the 2007 construction season, as a precursor to a series of projects that will see Highway 401 widened through Mississauga. The lower photo shows construction underway to elongate the Mavis Road overpass which is a precursor to a larger contract to extend the collector lanes westerly from Hurontario Street to the Credit River bridge.

View looking easterly from the McLaughlin Road overpass towards Hurontario Street. The upper two photos show Highway 401 with a 1970s era cross-section that was typical of virtually all freeways in Ontario constructed or widened during the 1960s and 1970s. Virtually all urban freeways in Ontario used to look like this before they were retrofitted with tall-wall barrier and high-mast lighting. While high mast lighting and tall-wall barrier are an improved design from an operational standpoint, it is unfortunate that Ontario's freeways are losing their past character as they are reconstructed. It is also unfortunate that truss lighting is not being used in new applications not suitable for high-mast lighting. The lower photo shows the cross-section of Highway 401 after the highway was widened to twelve lanes through the Hurontario Street interchange.

Looking westerly from the Hurontario Street (Highway 10) overpass in Mississauga. In the upper, pre-widening photo, notice the somewhat elongated configuration of this interchange. The elongated shape is due to the interchange ramps not being realigned when this interchange was converted from a cloverleaf design into a parclo A-4 type. The middle photo shows the highway during the construction project that saw collector lanes pushed through the Hurontario Street interchange. Additional photos taken during this construction project are available on the construction focus page. Finally, the lower photos show Highway 401 after the construction to add collector lanes through the Hurontario Street interchange had been completed. The first completed photo shows the interim configuration where the inner HOV lane remained closed, while the final two photos were taken after the collector lanes had been extended to beyond Mavis Road.

Hurontario Street carried the Highway 10 designation until it 1998 when all urban sections of the Highway were transferred to local municipalities. Click here for Highway 10 images.

Highway 401 is being widened from six to twelve lanes between 2009 and 2013 through Hurontario Street. Click here for more information and photos.

Looking east along Highway 401 from the Highway 10 overpass. Highway 10 is located at roughly kilometre marker 342. Now that the highway has been widened to twelve lanes, the cross-section that is pictured in the upper photo, before the widening project started is almost unrecognizable compared to the lower photo.

Westbound views in both the express and collector lanes approaching the Hurontario Street overpass. The third westbound express lanes exits at the Hurontario Street interchange. In the future, when the collector lanes are extended further west through the Mavis Road interchange, an HOV lane will begin in the express lanes at this off-ramp. The HOV lane is envisioned as far west as the Highway 24 interchange in Cambridge.
