Northfield / 85 Exchange upgrades?

If you look at the report that was linked up on page 2, the painted median is only 2M wide through the bridge span itself. It tapers down quite quickly off the span. Given this I think the design decision not to use it to widen the bit lanes makes a bit more sense.

Well, not widening the car lanes is definitely the right choice, but there's still no reason not to widen the bike lanes or buffer them from car traffic, given the configuration of the ramps, it looks like they're struggling with what to do there.  I can imagine many cars will just use the bike as a merge lane.  Quite frankly, putting the buffer between cars and bikes, on both sides of the bridge, and using flexible bollards would have been the right choice IMO.
