About the Project
The southbound 170 Street Bridge over the CN Rail yard (known as B171) will undergo rehabilitation work in 2017. This will include deck removal and replacement, barrier rehabilitation, and abutment rehabilitation. Some underdeck bridge work, including pier repairs and slope protection repair/replacement, will be done on both B171 and the northbound bridge (known as B170).
It is anticipated that there will be minimal construction impacts to adjacent businesses along 170 Street. Traffic in both directions will be restricted but remain open throughout construction with good alternate access in and out of the area.
Project Timeline
2017: Construction (anticipated spring through October)
2016: Preliminary and detailed design work
2015: Bridge condition assessments
Project History
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.
Construction Update - April 2017
April 14, 2017 - Traffic will be split starting Monday April 17 for bridge construction. Work is expected to take six months.
Project Update - March 2017
Starting at 9am on Monday March 27, the 170 Street Bridge will be reduced to two lanes in both directions for removal of curb and gutter and installation of temporary asphalt in preparation for the six-month road closure for bridge rehabilitation.
The southbound bridge will close to traffic in mid-April.
Traffic Impacts
Traffic will be split to two lanes in each direction on the northbound bridge deck for the duration of the project. Drivers can expect travel delays.
