Highway 401 Widening - Highway 8 to Townline Road

[Viewfromthe42]

So my vote goes: Wide, thick, but identically-spaced white markings when new permanent lanes come in, signifying to keep your space from these lanes for a bit, but they will become part of the flow. Regular width, but more frequent/densely packed lines, showing a lane is about to end, and those tightly packed white lines will soon become a solid white line, e.g. the standard right-edge-of-highway marking.
