19 Street Improvement Project

Construction Season_700x400

The 19 Street Improvement Project will improve safety, movement and capacity on one of Red Deer’s major arterial roadways. This project is big, and will take place over the 2023 and 2024 construction seasons to complete the following:

  • Roadway rehabilitation: 19 Street between Irwin Avenue and Gaetz Avenue is a road in need, with the entire road infrastructure requiring upgrades to maintain the road’s integrity.
  • Roundabout at 19 Street and 40 Avenue: Construction of a multi-lane modern roundabout at 19 Street and 40 Avenue, will improve intersection capacity, reduce overall traffic delays and improve safety for all road users.
  • Trail connections: New multi-use trails will be built to provide better multi-modal connectivity between neighbourhoods, parks, and commercial spaces.

19 street Project-Overview

19 street Roundabout

During construction in 2023, traffic will be reduced to one lane in each direction and the intersections at 49 Avenue, 46 Avenue and Sharpe Avenue will being right-in and right-out only. This is being done to ensure traffic flows more easily and with the safety of drivers in mind.

These diagrams show how traffic will be able to access businesses on 49 Avenue, 46 Avenue and Sharpe Avenue during construction. All businesses will remain open during construction, it just might take a few more minutes to get there.

Why do we need a complete reconstruction?

Asphalt roads get their strength from the quality of the subgrade, base course and asphalt layers. The subgrade and base course are layers with varying degrees of manufactured gravels. Subgrade has very little manufacturing and is generally made up of natural soils, that are good for road building, mixed with some uncrushed rock. Compacted well, it helps support the base course and asphalt. Base course is manufactured and, when compacted well, it helps to support the asphalt layer while allowing water to drain away from the pavement and subgrade. Complete reconstruction involves removing the existing asphalt, base course and subgrade and reinstalling with new material. 

Water is the biggest challenge in the health of a road. Over time, when the pavement cracks, water can weaken the base course and subgrade. When the layers beneath the pavement get weak, the pavement breaks up under the traffic load and that’s what is happening on 19 Street. Complete reconstruction will provide new subgrade and base course to support the brand-new pavement.

Why does it take so long?

Because 19 Street sees a lot of traffic, the pavement structure is deep: almost 1 metre in some places. The contractor will have to remove the existing material and replace it with new material. To keep things dry, the contractor works in small sections, ensuring that they don’t have long sections of roadway open allowing water into the subgrade when it rains. 

Why are we improving this intersection?

During peak traffic volume times, some traffic movements experience significant delays at this intersection. In 2020, the overall intersection delay was 30 seconds. A project team explored various options to solve this issue. One option was to add lanes to the existing signalized intersection, this option resulted in 31 seconds of delay. The multi-lane roundabout option resulted in 6 seconds of delay.
