Completed overpass

This area is being upgraded to support future residential, commercial and industrial growth of the Sherwood Park urban service area. 

The Range Road 231 rail overpass project includes: 

  • County-led roadway upgrades from Clover Bar Road/Range Road 231 from Emerald Drive to 750m north of Highway 16. 
  • Road re-alignment and an overpass built over CN Rail. Initial construction will include a three-lane overpass, with long-term design plans for a six-lane roadway cross section.  
  • Upgrades from a two-lane rural road into a two-lane urban road with concrete curb and gutter, streetlighting, and general urbanization improvements. 
  • Paved multi-use trail connection from Emerald Drive to north project limits. 
  • Intersection improvements at Emerald Drive and adjacent to Highway 16. 

Note: Phase 2 includes aligning Range Road 231 from north of Highway 16 to south of the overpass. A detour is in place until this phase is completed in 2025. 

Other North of Yellowhead Upgrades construction projects include:  

  • Developer-led roadway upgrades along Range Road 231 from north of the CN Rail overpass to 2.2km north of Highway 16.  
  • County-led construction of water and sanitary lines 
  • Highway 21 and Township Road 534 – Intersection improvements, including road reconstruction, grading, paving, new traffic signals and lighting. 

Traffic impacts

Construction in the area will cause major delays. Area businesses will still be accessible, but some detours will be in place. Please watch for signs and slow down in construction zones, even when workers are not present.
