IBR PHASE 2: Phase 2 construction began in the summer of 2024, specifically situated between CR 4 and CR 54/10th Sideroad. This extensive project will span over three construction seasons, with a completion date expected in 2027. The scope of this project encompasses various essential components:

Intersection Improvements – CR 21/20th Sideroad: In conjunction with the IBR Project, the County is also making intersection improvements at CR 21 and 20th Sideroad in Innisfil beginning in 2026. This work will occur over two construction seasons, achieving completion in 2027. CR 21 will be widened to 4 lanes and tie into the new multi-use trail on CR 21 and the existing multi-use trail on the north leg of 20th Sideroad. Work includes installing:
- curb, gutter and stormwater improvements
