ONTARIO MINISTRY OF TRANSPORTATION (MTO) 
Highway 15 and County Road 42 Intersection Improvements
Township of Rideau Lakes, United Counties of Leeds and Grenville

The approved TESR focuses predominantly on short-term improvements, however, MTO is updating the Preliminary Design to evaluate long-term intersection improvements that include:
 

• Alternative 1 – Realignment
  Alternative 1 includes a significant alignment shift of Highway 15 to the west with improvements to County Road 42. In addition, the intersection would be shifted from its existing location, the existing superelevation (curve through the intersection) is removed and the angle at which County Road 42 crosses Highway 15 would be improved.
   

• Alternative 2 – Offset T-intersections
  This alternative was identified as Alternative 3-2 in the 2017 TESR and brought forward with refinements to the original design. Previously, this alternative was shown as impacting the culvert crossing of Sucker Creek on County Road 42, east of the intersection. The alternative has been refined to avoid impacts to the culvert and associated fish and fish habitat.
   

• Alternative 3 - Roundabout
  This alternative was developed with the potential to minimize environmental impacts, including property requirements, improve sight lines and remove the curve through the intersection.
