My top 10 Manitoba-wide overpasses, in priority-ish order, with AADT, would be:
1) Bishop @ St Mary's/Dakota .....(57,000 x 31,600) ..7th in accidents
2) Bishop @ River Road ..............(67,300 x 5,400) ....Or delete light elsehow
3) Kenaston @ McGillivray ..........(53,600 x 21,700) ...1st in accidents
*4) Lagimodiere @ Regent .........(52,300 x 36,500) ...3rd in accidents, but no room
5) Lagimodiere @ Dugald ...........(52,300 x 26,200) ...Combine Marion
6) Perimeter @ Pipeline .............(25,540 x 1960) .......Cheap
7) Perimeter @ St Annes ............(27,340 x 12,300) ...Expensive
8) Deacons Corner ....................(20,120 x 6290) .......Cheap
9) TCH @ Yellowhead ................(8670 x 3690) ..........Cheap, dangerous
10) TCH @ Carberry...................(8300 x 2520) ..........Cheap, political
11) Perimeter @ McGillivray .......(21,520 x 8040)
Problem with McGillivray/Perimeter is the design is horrible + expensive. Traffic is low-moderate. And even if you overpass it, you've still got 3 more EB lights at La Salle Road, Kenaston, Waverley. So what have you really solved for a ton of money?
Most of the above create large free-flow sections at a time (River, Pipeline, St Annes, Deacons). They eliminate that 1 nuisance light. Levels of gov't need to work together here. Winnipeg needs their share of the pot.
