Construction on 2017 Main Street Project is scheduled from mid-April through to the end of October, with work proceeding in five stages along Main Street (50 Avenue) - east to west from Highway 2A to 53 Street - to minimize the impact on downtown businesses and residents.

Public sidewalks and area businesses will be open during construction. Look for onsite signage for more information.

Construction Stages

Pre-Staging - Asphalt milling

Construction signage and barricades are placed around the whole project area in preparation for short-term, rolling road closures. Milling machines are in high demand throughout the summer, so milling the whole project area at once is both efficient and cost effective.  The milling process on Main Street and 49C Avenue takes approximately 2-3 days to complete.  Since the milled road is approximately 100mm lower than the existing asphalt, smooth tapers are placed at intersections and crossings.  Once complete, temporary line markings are painted. 

Milling machines grind old asphalt into a recycled asphalt product that manufacturers use to make more asphalt, which is used as temporary road surfaces on Main Street and on 49C Avenue.

Main Street Stage 1

   

Stage 1: Estimated construction start - mid-April; estimated opening in late June.

Construction takes place as per the sequence described here.

Road closures are in effect at the 50 Street intersection, 49 Street, and Highway 2A.  Sidewalks remain open and business access is unaffected.  Pedestrian crossings will be in place as shown. Parking signs will be installed around the project area to direct motorist to nearby public parking lots.  To help plan your downtown activities this summer the City has produced a number of maps (link).

 Main Street Stage 2    

Stage 2: Estimated construction start - mid-May; estimated opening in late July.

Construction takes place as per the sequence described here.

The road closure is expanded to the 51 Street intersection and the south end of 49C Avenue as the sanitary main replacement crew continues moving west.  East of the 50 Street intersection, the concrete crew installs the 49 Street turnaround, constructs the new access to the Flatiron Plaza parking lot and replaces the sidewalk, curb and gutter.

The sidewalks remain open and business access is unaffected.  Pedestrian crossings will be in place as shown.

 Main Street Stage 3    

Stage 3: Estimated construction start - mid-June; estimated opening in mid-August.

Construction takes place as per the sequence described here.

The road closure is expanded to the 52 Street intersection as the sanitary replacement crew continues moving west.  East of the 49C Avenue intersection, the concrete crew replaces the sidewalk, curb and gutter. The sidewalks remain open and business access is unaffected.  Pedestrian crossings will be in place as shown.

Stage 1 area is opened to motorists on a temporary road surface, and landscaping/streetlight crews may be onsite in this area.

 Main Street Stage 4    

Stage 4: Estimated construction start - mid-July; estimated opening in early September.

Construction takes place as per the sequence described here.

The road closure is expanded to the west of the 52 Street intersection as the sanitary replacement crew continues moving west.  East of the 52 Street intersection, the concrete crew replaces the sidewalk, curb and gutter. The sidewalks remain open and business access is unaffected.  Pedestrian crossings will be in place as shown.

Stage 2 area is opened to motorists on a temporary road surface and landscaping and streetlight crews may be on site in stage areas 1 and 2.

 Main Street Stage 5    

Stage 5: Estimated construction start - mid-July; estimated opening in early October.

Construction takes place as per the sequence described here.

The road closure is expanded to west of the 53 Street intersection as the sanitary replacement crew continues moving west.  East of the 53 Street intersection, the concrete crew realigns the 52 Street intersection, constructs new pedestrian bulb-outs and replaces the sidewalk, curb and gutter.  The sidewalks remain open and business access is unaffected.  Pedestrian crossings will be in place as shown.

When the sanitary replacement crew is complete, the concrete crew moves west and completes the sidewalk, curb and gutter replacements west of 52 Street. 

Stage 3 area is opened to motorists on a temporary road surface. Landscaping and streetlight crews are very likely in stage areas 1-3. 



Post Staging – Final road construction, temporary line markings and final asphalt

Construction signage and barricades are placed around the whole project area in preparation for short-term, rolling road closures.

Road crews prepare the road base to its final profile and pave the bottom and middle lifts of asphalt. Road crews are in high demand throughout the summer so this portion may be done in whole or half the project at a time depending on construction progress and impact to businesses.  Once complete, temporary line markings are painted.  This concludes the 2017 work. 

Final Asphalt and final road markings take place in 2018, at which point construction signage and barricades are placed around the whole project area in preparation for short-term, rolling road closures.  Deficiencies, such as trench settlement that may be apparent are corrected prior to the placement of the final lift of asphalt.  The top and final lift of asphalt is placed and permanent line markings installed.  Paving and line marking is estimated to take approximately 3-5 days to complete.
