I drove the Regina Bypass earlier today. A few quick notes, on my way out of Regina:
-- The part of the Bypass that is TCH 1 (including the final phase south of Regina, and earlier phases east to Balgonie) has exit numbers, which run from east to west from 217 in Balgonie to 258 on the west side of Regina. For some reason, the provincial highways ministry logs its cross-province routes that way, in this case starting at the Manitoba border. I think these exit numbers are Saskatchewan's first, though there is at least one older lettered exit on SK 11 north of Regina.
-- It's all four lanes or sometimes more divided, with a posted 110 km/h speed limit except approaching the Bypass terminus at SK 11 exit 19. This includes the part of the Bypass along the west side of Regina, onto which SK 11 was rerouted (originally it connected to the TCH on the east side of Regina, at a congested interchange with Victoria Ave.).
-- While every intersection has exit-numbered ramps, there are two with at-grade minor-road crossings: Courtney Avenue on the TCH at exit 253, and Armour Road at SK 11 exit 14. There are no traffic lights at those intersections, and no reduction in the 110 km/h speed limit.
The Bypass is a longer but faster route through the Regina area, and is a big improvement over the TCH's earlier routing along parts of the older Ring Road freeway and Victoria Ave.
