Project Overview
Rehabilitation of Highway 519 to improve safety, pavement condition, drainage, and structural integrity, while ensuring environmental protection and minimizing community impact.
Key Components
- Grading & Drainage Improvements – Pavement rehabilitation using in-place processing, addition of Granular 'A', and culvert replacements,
- including minor drainage upgrades and catch basin adjustments.
- Hot Mix Asphalt (HMA) Paving – Placement of a 50 mm SP 12.5 surface course, with a 25 mm grade raise to improve ride quality and surface durability.
- Structural Work – Twin Lakes Culverts (Site No. 38C-047):
- Replacement of structural plate elliptical culverts with scour protection.
- Maintenance of existing concrete cut-off walls and replacement of guiderails.
- Use of temporary detour with a restraining soil system and portable traffic signals during culvert replacement.
- Electrical Work – Reinstate existing traffic counting station loop and install temporary traffic signals at Twin Lakes Culverts.
- Environmental Protection – Erosion and sediment control, in-water work timing restrictions, and fish habitat enhancements including enlargement of walleye spawning shoals.
Challenges & Solutions
Project Impact & Benefits
- Extended service life of Highway 519 and improved road safety.
- Enhanced drainage systems and culvert replacements reduce flood risks and support long-term sustainability.
- Improved travel conditions with a smoother road surface and updated guiderails.
- Protected sensitive fish habitats and enhanced walleye spawning grounds.
- Contributed to reduced greenhouse gas emissions by improving traffic flow and minimizing construction-related resource use.
Construction Overview
The 6-month project followed the Design-Bid-Build model, successfully addressing pavement deterioration, drainage deficiencies, and structural vulnerabilities. Strict environmental management ensured compliance with regulatory requirements and protection of sensitive ecosystems. The rehabilitation of Highway 519 strengthened the region's transportation network while supporting local economic activities and community needs.
