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
