CR 23 (Buckhorn Road) and CR 22 (Curve Lake Rd/16th Line) - Intersection Enhancements

The County of Peterborough, together with their Consultant, D.M. Wills Associates Ltd., is undertaking a Municipal Class Environmental Assessment (MCEA) to complete intersection enhancements at CR 23 (Buckhorn Road) and CR 22 (Curve Lake Rd/16th Line).

The general location of the Study is shown in the figure below.

The Process
This Study is being conducted in accordance with the requirements of a Schedule ‘B’ of the MCEA, October 2000, as amended in 2023. This Schedule ‘B’ Environmental Assessment requires Public Consultation, Indigenous Community Engagement, Archeological Assessments, and Natural Environment Assessments.

Background Information

The intersection was identified in the 2022 update of the County’s Transportation Master Plan (TMP) as requiring enhancements to increase the level of service (traffic operations) and improve traffic safety in the short term. The TMP also identified the need to enhance the intersection to accommodate future growth.

CR 22 and CR 23 are classified as arterial roads; CR 23 has a high volume of truck traffic. The intersection presently meets the warrants for traffic control signals and was also screened as a candidate for a roundabout in the TMP. Roundabout screening considered the following factors: safety concerns, atypical geometry, unbalanced turning volumes, and property availability.

The existing Level of Service (2021) for the PM peak hour (worst case scenario) is currently Level C, with future scenarios projected at Level E and F. Critical conditions were noted for the northbound and southbound approaches of the intersection during the PM peak hour. Conditions are amplified by seasonal traffic volumes. Current modelling (2023) predicts the Level of Service to be A and B for the roundabout and signalized options, respectively. For information Level of Service is described as;

• Level A (free flow)
• Level B (stable flow, slight delays)
• Level C (stable flow, acceptable delays)
• Level D (approaching unstable flow, tolerable delays)
• Level E (unstable flow, intolerable delay)
• Level F (forced flow, queues fail to clear)
