A few photos of some ongoing construction along the 401 in the eastern GTA:
Construction at the 404/DVP interchange has exposed the concrete road base of the westbound collector lanes. The collector lanes have been reduced to two lanes through the construction zone, while a fifth lane has been temporarily added to the express.

At Warden, the joints of the concrete are indicative of when the westbound collector lanes were only two lanes wide through the interchange.

Half of the Lakeridge Road has already been demolished. I suspect it will be sometime before the section over the rail lines comes down.

View looking easterly as Highway 401 passes beneath the future ramp to the eastbound 401 from Highway 412.
