170 Street is a major north-south arterial roadway connecting Edmonton industrial, commercial, and residential areas with St. Albert and Yellowhead Trail/Highway 16.
The intersection of 170 Street and Yellowhead Trail features 3 bridges: 2 side-by-side over the CN Rail yard (B170 northbound and B171 southbound); and 1 with 2-way traffic over Yellowhead Trail (B185). B185 was completed in 1982, with B170/B171 completed in 1983. The bridges include 3 lanes of traffic in both directions, turning lanes onto Yellowhead Trail, and a sidewalk on the east side. This was the first major rehabilitation of these bridges.
