Project Overview
Reconstruction of a key corridor on Highway 7/8, enhancing safety, drainage, traffic control, and the CVIF facility.
Key Components
- Grading & Drainage Improvements – Earth excavation, ditching enhancements, culvert and sewer replacements, and crossfall adjustments to maintain existing drainage patterns.
- Granular Base & Hot Mix Paving – Full-depth asphalt removal and replacement with Granular A, Superpave 19.0 (binder), and Superpave 12.5 FC 2 (surface). Concrete pavement installation at the CVIF.
- Traffic Control Upgrades – Replacement of the traffic signal at Perth Road 107, new electrical works for the CVIF, and installation of new signage to enhance traffic safety and flow.
- Commercial Vehicle Inspection Facility (CVIF) Reconstruction – Complete facility upgrade to current standards, including equipment replacement and improved site layout for safety.
- Utility Coordination – Relocation of Bell, Hydro One, Union Gas, and Rogers utilities prior to construction, with pole support managed during the works.
- Environmental Protection – Implementation of erosion control measures, tree clearing restrictions, and planting of new trees throughout the corridor.
Challenges & Solutions
Project Impact & Benefits
- Improved pavement condition, resulting in smoother driving surfaces and enhanced road safety.
- Upgraded drainage systems extend service life and reduce flooding risk.
- Modernized traffic control systems and signage improve overall traffic flow and safety.
- Enhanced CVIF operations through site improvements and updated equipment.
- Environmental protection through strategic tree planting, erosion control, and conservation of natural areas.
Construction Overview
The project was delivered over a 12-month period, following the Design-Bid-Build model. Long-term and short-term single-lane closures were implemented throughout the construction period, ensuring minimal disruption to traffic while maintaining safety standards. The final infrastructure upgrades significantly enhanced the roadway's durability, traffic safety, and drainage capabilities, while also modernizing the CVIF for more efficient operations.
