Yea to fully upgrade perimeter will be a large chunk of change. Largest interchange in the province, 59 and 101, cost 204 million (at the time it started, last I heard there were no major cost overruns). Biff posted a while back that diamonds run for about 20 million, cloverleafs 40-50 million. High speed ramps probably add a lot of costs. The Roblin overpass rehab was about 35 million. Let’s go through a hypothetical list of interchanges and modifications that WSP might suggest for S perimeter, from W to East based on the RFP document:
Portage: Downgrade to partial cloverleaf to eliminate weaving. Won’t need full cloverleaf once headingley bypass is built. Split to 2 bridges to allow 6 lanes, and Increase ramp lengths – 60 million
Assiniboine river bridges – rebuilt or widened to accommodate 3 lanes each way – 40 million
Roblin – All good, just rehabbed, ready for 3 lanes each way
Wilkes – Separate to 2 bridges, widened to accommodate 6 lanes, increase ramp length – 50 million
Wyper Rd. – diamond when needed, long term – 20 million
Mcgillivray – upgrade to parclo, realign mcgillivray/hwy 2/hwy 3 cluster – 60 million
8 mile road – diamond when needed, long term – 20 million
330/Brady rd area – diamond or parclo and rail overpass– 50 million
Kenaston (close Waverley) full interchange with at least 2 high speed ramps (WB to SB, NB to WB), may be built with St Nob bypass or like centreport with ramps and roadway ready for when the highway gets built – 250-300 million
Pembina – Downgrade to parclo to decrease weaving once St Nob Bypass is built, add exchange collector lane for exits and use current 3 lanes in each direction on the bridge for through traffic – 40 million
Red river – Build 2nd bridge to allow 3 lanes in each direction – 40 million
St Mary’s – Parclo – 40 million
St Anne’s – Diamond – 20 million
Railroad and Seine River crossing – Overpass, likely retaining wall rather than groundwork due to nearby businesses – 30 million
59 South – Make full cloverleaf with exchange collector lanes to decrease weaving or downgrade to parclo if City gives up on Lagimodiere ever being free-flow. 50 million
Symington – Diamond, 20 million
Fermor – Widen to 2 bridges to allow 3 lanes each way, make WB to SB loop ramp into a high speed ramp – 120 million
Total 910-960 million depending on kenaston, just for interchanges on South Perimeter. Nevermind widening the highway to 6 lanes and removing to jersey barriers to make a proper median, and adding services roads where needed. Throw in North Perimeter and it will likely near 3 billion for it all.
