Project Background

• The existing Vinca Bridge was built in 1967 and needs to be replaced due to its age and the condition of the structure.

• The Vinca Bridge has been identified as the preferred crossing over the North Saskatchewan River for Over-sized / Over-weight Loads heading to northern Alberta.

• Currently, the bridge serves 1500 vehicles per day, 24% of which are large trucks.


Project Considerations

• The North Saskatchewan River channel is stable due to upstream dams, but the bridge crossing should still be perpendicular to water flow.

• Steep river banks and removing vegetation for construction could reduce slope stability. This needs to be considered during construction staging.

• The bridge over Beaverhill Creek is in good condition and and will not be impacted by this project.


• 3 watercourses in the study area

• North Saskatchewan River

• Redwater River

• Beaverhill Creek

• 16 wetlands

• Numerous tree stands

• 6 Non-reclaimed Environmentally Sensitive Area sites

Option 1: Not recommended because it bisects agricultural farmland, requires a skewed bridge and impacts the Red Water River and 3 historical sites.

Option 2N: Not recommended because it impacts the Red Water River, an Environmentally Sensitive Area and 3 historical sites.

Option 3: Not recommended because it bisects agricultural farmland and would require raising the Highway 38/830 intersection, which increases construction detouring.

Option 4: Not recommended because the posted speed limit would be lower than what the project was trying to achieve.
