Abstract

The Calgary TraiVGateway boulevard interchange at Anthony Henday Drive in Edmonton is a "Systems" interchange. Four of the many flyovers at this interchange have underpassing roadways with curved horizontal alignments. Structure ES (Eastbound - Southbound) and structure NW (Northbound - Westbound) are flyovers over Calgary Trail southbound, which has an 800m Radius at ES and tangent section at NW. Structure NW is on a 600m Radius and 4.8% superelevation. Structures El and W3 are carrying Anthony Henday Drive mainline over Anthony Henday Northbound Westbound, which is on a 400 radius and 5.7% superelevation at this location. Structures El, W3 and ES have to accommodate future widening on one side. This paper describes the design challenges and solutions arrived at, taking in account safety, economy, functionality and aesthetics. For the covering abstract of this conference see ITRD number E211426.
