Highway 11 Class Environmental Assessment and Preliminary Design Study From 1.0 km South of Simcoe Road 169 Northerly to Muskoka Road 169 Gravenhurst Committee of the Whole and Council Meeting December 21st, 2010 Agenda Timing of Study Activities Summary of PIC #2 Review of Future Traffic Projections Overview of Highway 11 Mainline Alternatives Overview of Highway 11 Realignment Alternatives What’s Next? Question and Answer Period Study Area Timing of Study Activities Summary of PIC #2 Held on September 23rd, 2010 at the Muskoka Boat and Heritage Centre Attended by ~ 280 The following was presented: Assessment and evaluation of mainline widening and service road alternatives; Realignment alternatives still under consideration and initial assessment; Specific interchange configuration alternatives. The following summarizes some of the key feedback received: A realignment east of Gravenhurst should be avoided; More information about property specific impacts is needed; Businesses along Highway 11 may not be viable if a realignment is selected; Removal of direct access to Highway 11 may affect viability of some businesses; What is the schedule for this work? Future Traffic Projections Traffic volumes obtained from September 2009 surveys were combined with historical growth rates to project future volumes. MTO will consider widening Highway 11 to six lanes when level- of-service “LOS E” is reached. It is anticipated that this will occur within the 2038 planning horizon. Highway 11 Mainline Alternatives Widening, realignment and service road alternatives have been developed. As presented at PIC #2, a widening of Highway 11 is generally preferred from Simcoe Road 169 to North of Luigi Road, with the exception of: South of Kilworthy Rd to Luigi R - a realignment to the west is required to improve curve. Widening will occur either to the west, to the east or about the centreline. From North of Luigi Road to Muskoka Road 169, both widening and realignment alternatives are still being assessed. Highway 11 Realignment Alternatives – Kilworthy Bypass Alternatives 1 & 2 Significant impacts to fish habit – new crossing of Kahshe River Significant impacts to residential and commercial properties S-curve (Alternative 1) Alternative 3 Displaces “Little Red School House” Impacts future development Lower impacts to fish habitat Fewer impacts to residential and commercial properties Provides best secondary access to existing properties Realignment Alternatives – Luigi Road to Muskoka Road 169 Four realignment alternatives were developed in the north area and carried forward for assessment and evaluation: Realignment East of Gravenhurst – Alternative 1; Realignment East of Gravenhurst – Alternative 2; Local Realignment - Alternative 1 (to east); and, Local Realignment – Alternative 2 (to west); Following PIC #2, the four realignment alternatives were assessed and evaluated to determine the preferred realignment alternative. In the coming weeks, the preferred realignment alternative will be compared to the preferred widening/service road alternative between Sedore Road and Muskoka Road 169. Highway 11 Realignment Alternatives – Realignments East of Gravenhurst Alternative 1 New crossing of Gull Lake 5 residential displacements Significant impacts to Jevins and Silver Lakes Conservation Reserve and Jevins Lake PSW Diversion of traffic away from highway dependent businesses south of Gravenhurst Impacts areas of high archaeological potential Alternative 2 Most significant impacts to Jevins and Silver Lakes Conservation Reserve and Jevins Lake PSW Most watercourse crossings Diversion of traffic away from highway dependent businesses south of Gravenhurst Impacts areas of high archaeological potential Highway 11 Realignment Alternatives – Northerly Local Realignments Alternative 1 Major impacts to Beaver Ridge Estates S-Curve approaching Muskoka 169 interchange Requires shift of Muskoka Road 169 interchange further into Jevins Lake PSW – environmental and constructability issues Diverts traffic away from highway dependent businesses along Highway 11, but may still be relatively visible Alternative 2 Bisects Muldrew Barrens Conservation reserve – Species at Risk (SAR) Two crossings of CN rail tracks Provides improved geometrics compared to Alternative 1 Ties into existing Muskoka Road 169 interchange Diverts traffic away from highway dependent businesses along Highway 11, but may still be relatively visible Highway 11 Realignment Alternatives – Realignment vs. Existing Local Realignment Alternative 2 Bisects Muldrew Barrens Conservation reserve – Species at Risk (SAR) Two crossings of CN rail tracks Ties into existing Muskoka Road 169 interchange Diverts traffic away from highway dependent businesses along Highway 11, although may still be relatively visible Widen Existing Highway 11 to the West Greater business impacts, but businesses on west side are highway dependent and may choose to relocate No impact to businesses on east side of Highway 11 Minor encroachment on Muldrew Barrens Conservation reserve – Species at Risk (SAR) Ties into existing Muskoka Road 169 interchange Maintains visibility and good access for businesses that remain on the east side of Highway 11 What’s Next Complete the evaluation of the preferred widening vs. preferred realignment alternative in north area; Throughout Consultation Complete the assessment and evaluation of interchange alternatives; Present the conceptual recommended plan at PIC #3 – Early 2011; Continue with preliminary design of recommended plan; Present preliminary design of recommended plan including proposed mitigation measures at PIC #4 – tentatively June 2011; Prepare TESR for public review – Fall 2011.
