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

Main Street 2017 Construction Schedule


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. 

2018 Final Paving and Permanent Line Markings

It is the City’s goal to limit disruptions to the Lacombe’s downtown to as short of a timeframe as we can while maintaining quality and safety requirements. 

To that end starting Monday (July 9, 2018) morning (about mid morning) crews will be temporarily closing Main Street and 49C Avenue to motor vehicle traffic between 53rd Street and Highway 2A. This will allow multiple crews to have full access to the work zone at all times so they can work concurrently.  This closure is anticipated to remain in place until the end of day on July 18th.  

Sidewalks will remain open and pedestrian access to businesss will not be affected by the temporary road closures. However be advised that a early step in the paving process is the application of what is know n as a “tack coat” on the current asphalt surface that will last 2 days prior to paving. The tack coat helps to bind the current asphalt surface to the new asphalt.  It is black, very sticky and may be tracked off the road onto the sidewalk and potentially inside businesses by pedestrians or unsuspecting staff.  Crews will be laying road fabric and pylons at intersections to provide pedestrians a means of navigating downtown without tracking the tack coat. We encourage the public to use these crossings.

The general sequence of activities starting next week will be as follows:

July 9                   Road Closure and street sweeping

July 10                 Tack Coat

July 11                 Tack Coat and patching in front of Healthfitters

July 12 to 13        Paving

July 14 to 18        Permanent line markings

July 18                 Road Open

July 20 to ~27      Concrete repairs in front of Healthfitters

August                  Installation of planter hangers on street poles and correction of any other remaining minor deficiencies.
