RR 233 – Hwy 830 (Wye Road) to Hwy 628 (Roundabouts)
Analysis & Functional Planning Study
Strathcona County

Al-Terra initially developed a simulation model to compare a two-lane roadway with roundabout intersections to a four-lane roadway with conventional intersections as options for Range Road 233. This important arterial road provides access to collector roads serving several estate subdivisions.

Al-Terra was then asked to develop a functional plan for this 3-km roadway and six roundabout intersections. Cost comparisons indicated that major savings would be achieved, by deferring four-lane widening, and by using single lane roundabouts to meet traffic demand safely, and eliminate the need for signals.
