Project Highlights:
The 2km reconstruction of York Road from Gladstone Avenue to Highway #9 was the largest budget ever approved by Yorkton City Council. To optimize the flow of traffic and minimize future operating costs, the existing 5-lane roadway configuration was reduced to 3 lanes.
Prior to construction, a competitive 2-pavement tendering process was utilized to assess life cycle costs of surfacing structures for both asphalt and concrete roadway options.
The 2-year construction period involved significant planning to provide access to existing businesses along the 2km corridor during construction. Traffic accommodation and detour plans were put in place for more than 10 separate phases of construction.
To manage significant storm water flows through the corridor, 26 storm water manhole chambers were replaced or installed along with 1.74km of storm sewer mains ranging from 375mm to 1,500mm in diameter. 62 high capacity catch basins along with 585m of 300mm and 450mm catch basin leads were also replaced or installed and connected to 3.65km of weeping tile which will serve to keep the core of the roadway from becoming saturated during extended periods of wet weather.
CN permits were acquired for 185m of smooth wall steel pipe ranging from 1,050mm to 1,500mm that was installed via open cut and auger bored construction methods through existing CN railways. 88m of 1.8m x 2.4m box culverts along with 850m of channel improvements through the Victoria drainage corridor were also completed as part of the project.
Extensive engagement with private and crown utility corporations prior to construction was necessary to maintain the 2-year construction schedule. Utility crossings and necessary alterations were carefully coordinated with construction operations.
Asphalt from the existing roadway was milled and utilized within the proposed roadway surfacing structure, which resulted in significant cost savings to the project.
3.15km of concrete curb and gutter were replaced along and 32,870m2 of roadway was reconstructed.
360m of 150mm to 300mm diameter water mains were replaced along with approximately 15 commercial water and sewer services.
15 sanitary manholes and 1.25km of sanitary sewer mains ranging from 200mm to 750mm in diameter were replaced.
