Ironic enough... I start this thread because I couldn't easily find any info on the TCH twinning in Saskatchewan... well, I dug a little deeper and found a nice description of a ~9km 4-lane bypass of the town Moosamin under construction, and a completition date estimated at fall 2008.
I also found some interesting info pertaining to the TCH in Regina.
Theres a new southeast ring-road planned, designed to bypass the current stretch where the TCH turns off and runs along the big-box strip along Victoria Avenue. There was also a $16.0M funding commitment towards a new interchange at Lewvan Drive, hopefully to begin construction next year.
(I kinda thought it was wierd how Regina has a freeway semi-ring road, yet theres an at-grade intersection with no traffic lights with a 4-lane expressway.
