As Grande Prairie continued to grow, traffic volumes along 68th Avenue increased significantly. To accommodate this demand, the existing two-lane roadway was upgraded to a four-lane arterial. The project also included the addition of a right-turn lane east of Resources Road, completing the intersection improvements at that location.
The project presented several challenges, particularly related to site conditions. Variable soil conditions required continuous monitoring throughout construction to achieve a suitable subgrade, and a tri-axle geo-grid was incorporated to strengthen the road substructure. In addition, removal of the existing roadway was necessary to lower the entire carriageway, allowing for proper tie-ins to the adjacent lands.
Some of the project highlights were:
- Design and construction inspection of approx. 500 meters of a four lane divided arterial roadway.
- The extension and replacement of portions of the existing storm water sewer system.
- Construction of a stamped coloured concrete median.
- Installation of new traffic signals at the Poplar Drive intersection.
- Upgrade of the existing traffic signals at the intersection of Resources Road.
- Installation of approximately 400 meters a separate sidewalk.
- Roadway remained open to the public for entirety of the project.
- Successful completion of the project within budgeted parameters.
