McKay Road Interchange and Salem / Lockhart Crossing The McKay - PowerPoint PPT Presentation

McKay Road Interchange and Salem / Lockhart Crossing The McKay Road Interchange Class EA has two components: 1. A new MacKay Road Interchange at Highway 400; and 2. A new bridge crossing of Highway 400 at Salem / Lockhart Road.


  1. McKay Road Interchange and Salem / Lockhart Crossing • The McKay Road Interchange Class EA has two components: 1. A new MacKay Road Interchange at Highway 400; and 2. A new bridge crossing of Highway 400 at Salem / Lockhart Road. • The need and justification for these projects (Phases 1 and 2 of the Municipal Class EA process) was completed as part of the City’s Multi -Modal Active Transportation Master Plan MMATMP (2014) and is being confirmed through ongoing work with the Ministry of Transportation Ontario (MTO). • The current EA will complete Phase 3 (Design Alternatives) and Phase 4 (Environmental Study Report) of the Class EA process. • The design of these components will be integrated with the planned improvements to Salem / Lockhart Road and McKay Road, east and west of Highway 400. • The design of the McKay Road Interchange will also be integrated with MTO’s Highway 400 improvements, which include the current replacement of the McKay Road bridge and future widening of Highway 400. The McKay Road Interchange and Salem / Lockhart Crossing is subject to MTO approval.

  2. List of Studies Undertaken The potential improvement alternatives were presented at PIC #1. The next step in the EA process is to conduct an assessment and evaluation to compare the improvement alternatives, and identify a technically preferred alternative. The following list details the studies undertaken to provide input into the assessment and evaluation of improvement alternatives for the Salem / Lockhart Road Crossing and the McKay Road Interchange. Study Key Conclusion Archaeological Assessment Site of significant archeological potential in the northeast quadrant at McKay Road interchange location (Huron-Wendat Village). Drainage and Stormwater Management Two SWM ponds will be required at the McKay Road interchange. The SWM (SWM) Plan plan at both locations will integrate with the drainage management plan of Highway 400 corridor. Natural Environment Lovers Creek Swamp (Provincially Significant Wetland) is located within the vicinity of the Study Area. No Areas of Natural Scientific Interest are present in the vicinity of the Study Area. One watercourse present in study area. Traffic Operations / Analysis To be completed. Traffic data required from ongoing concurrent project Noise Assessment To be completed. Traffic data required from ongoing concurrent project Geotechnical Assessment No geotechnical concerns identified

  3. Design Alternatives Evaluation • Design alternatives were developed at both McKay Road Interchange and Salem / Lockhart Road Crossing locations and were presented at PIC #1. The alternatives have since have undergone a detailed assessment Evaluation Criteria and evaluation to identify the preferred alternatives. Factor Area Criteria • The assessment and evaluation utilized 1.1 Property and Access four key factor areas within which the 1. Socio-Economic 1.2 Community Environment evaluation criterion were established. 1.3 Land Use 2.1 Built Heritage / Cultural Heritage Landscapes • Study area constraints that factored 2. Cultural Environment 2.2 Archaeological Resources into the decision-making process were 2.3 First Nations Interests detailed at PIC #1. 3.1 Watercourses / fish habitat 3.2 Vegetation • The following boards summarize the 3.3 Designated Natural Features results of the assessment and 3.4 Wildlife 3.

  10. Salem Road Reservoir & Pumping Station • City of Barrie’s Infrastructure Master Plan: Water Storage and Distribution Master Plan (2013) identified an need for a pumping station and reservoir located on Salem Road. • Water Storage and Distribution Master Plan (2013) fulfilled the Municipal Class Environmental Assessment (EA) Schedule B for the planning of the water supply system. • General locations of system storage and pumping stations originally identified in the Master Plan were selected based on land use, topographic features and systems needs but the locations are conceptual and subject to minor changes due to land availability. • An assessment of potential reservoir locations undertaken as part of this assignment considered a range of environmental and technical factors including natural environment, cultural heritage, land use, groundwater etc.

  11. Reservoir Site Alternatives Evaluation Site 1 • Topography consistent with City of Barrie pressure zone operating levels, consistent with water and sewer servicing • Property size: 4.1 ha • Good access and adjacent to compatible land use – industrial / commercial • Site is conducive to future expansion to service growth Site 2 • Topography consistent with City of Barrie pressure zone operating levels, but offers less construction flexibility • Property size: 3.5 ha • Good opportunity for future expansion • Requires intrusion into more environmentally sensitive (i.e., forested) lands Site 3 • Topography consistent with City of Barrie pressure zone operating levels, but is only compatible with On Ground Cylindrical Reservoirs • Property size: 1.3 ha • Limited to relatively small parcel of land east of Hwy 400 • Limited access and adjacent to strict transportation and utility corridors • Limited to no capacity for expansion

  12. Preferred Site Selection Site 1 • Good access and adjacent to compatible land use • Easily accessible to watermain and sanitary trunk main along Salem Road • Greatest opportunity for future expansion • Site design and landscaping can be optimized to maximize compatibility with adjacent development adding versatility and net benefit to the area

  13. Sub-Grade Reservoir Option • Buried, cast-in-place concrete reservoir

  14. On-Grade Reservoir Option • Pre-stressed concrete design and construction • Glass-fused-to-steel design and construction

  15. Reservoir Design Options: Sub-Grade versus On-Grade Reservoir Criteria Selection Sub-Grade Reservoir On-Grade Reservoir Operations and Maintenance Conducive to current operational Conducive to current operational control control and integration with the existing and integration with the existing water water supply and distribution system. supply and distribution system. Operations and Maintenance Similar. Similar. Costs Capital Cost Capital costs are significantly greater: Capital costs are significantly less: • Excavation and shoring requirements. • Grading. • Cast-in-place concrete construction. • Pre-cast / pre-stressed concrete or glass fused-to-steel. • Both options are pre-fabricated off-site and delivered to site for assembly. Construction Duration 18 – 24 months. 12 – 16 months. (Estimated)

  16. Reservoir Site - Next Steps 1. Finalize conceptual reservoir design 2. Completion of life cycle cost analysis to finalize preferred reservoir design option • Preliminary preference is Site 1, On-Grade reservoir 3. Recommended reservoir location will be subject to review and permitting by regulatory agencies, including Lake Simcoe Region Conservation Authority 4. Geotechnical investigation to confirm suitability for construction
