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 three bridges: two side-by-side over the CN Rail yard (B170 northbound and B171 southbound); and one with two-way traffic over Yellowhead Trail (B185). B185 was completed in 1982, with B170/B171 completed in 1983. The bridges include three lanes of traffic in both directions, turning lanes onto Yellowhead Trail, and a sidewalk on the east side. This is the first major rehabilitation of these bridges. There is currently no timeline for further rehabilitation work on B170 and B185.
