This instersection currently experiences significant a.m. and p.m. peak period congestion that is complicated by the physical arrangement of the northbound/southbound lanes on Shaganappi Trail. Although the intersection is a candidate for interchange construction, it is not part of the current ten year stategic plan. As such, a smaller investment at this time, to improve the intersection will effectively extend the life of hte intersection while providing additional benefits to Calgary drivers. (Barbs note: You know what this means- the future plans of a long needed interchage will be pushed back even further!) The project is currently having supplies delivered to the site and work will commence spring 2012. The Link to the diagram shows Shaganappi Trail widened to three lanes in both directions and both turn lanes will be dual turns and lengthened. You will also see an earlier exit ramp from Northbound Shag to East bound John Laurie.
