1. Study Process
PHASE 1 : Problem/Opportunity
• Identify & describe the problem/opportunity.
PHASE 3: Alternative Design Concepts for Preferred Solution
• Identify and evaluate Alternative Design Concepts
• Identify environmental effects
• Select the Preferred Design
• Western Road/Wharncliffe Road North is a major north/south two-lane arterial road carrying approximately 20,000
vehicles per day.
• Existing capacity issues exist along the study corridor. The current rated capacity is Level of Service (LOS) F. Critical
failure of a system occurs at LOS F. Acceptable operations are generally considered to be LOS C or better.
• The need for widening of the corridor from Platts Lane to Oxford Street is identified in the City’s Official Plan, the
Long-term Transportation Corridor Protection Study, and the 2030 Transportation Master Plan (TMP).
• The TMP has also identified improvements to Oxford Street to accommodate turn lanes onto Wharncliffe Road North
and to accommodate transit priority measures at the intersection of Wharncliffe Road North and Oxford Street.

2. Study Context
• PIC #1 presented a number of alternative planning
solutions and identified the Preferred Solution as a
combination of Alternative 2: Expanded Pedestrian,
Bicycle and Rapid Transit Use and Alternative 5:
Arterial Road Widening.
• In isolation, Alternative 2 does not address the
problem. However, this alternative, in conjunction with
Alternative 5 will provide a multi-modal approach to
address the problem.
• Alternative 5 involves the reconstruction of Western
Road/Wharncliffe Road North to a four-lane cross
section, from Platts Lane to Oxford Street.
3. Results of PIC #1
• To provide interested and/or potentially affected
stakeholders with an opportunity to participate in the
planning and decision making process for this
Municipal Class EA.
• To present and receive public input on:
• Design options for Western Road/Wharncliffe
Road North;
• Design options for the Essex Street, Western
Road, Wharncliffe Road North, and Beaufort
Street intersection;
• Design options for the CP Rail subway;
• Design options for the Oxford Street/Wharncliffe
Road intersection;
• Preliminary preferred design alternative; and
• Next steps in the process.
4. Purpose of PIC #2
As part of the overall solution for the Western
Road/Wharncliffe Road North corridor, this study
also had consideration for the following:
1. Essex Street, Wharncliffe Road North,
Western Road, Beaufort Street intersection
improvements;
2. CP Rail subway widening; and
3. Single & double left turn lanes for south and
northbound Wharncliffe Road.
Alterative solutions were considered for each of
these components. The pre-screening process
allowed for each group of alternatives to be
assessed, and a preferred alternative was
selected to be incorporated in to the overall
preferred design alternative to solve the problem
statement.

5. Pre-screening
Three (3) alternatives were considered for implementation at the Essex Street/Wharncliffe Road North/Western
Road intersection:
Alternative 1:
Roundabout
Key Points:
• Reduces vehicle speeds.
• Fewer collisions.
• Difficult configuration for
higher pedestrian and transit
use, and lower side street
traffic volumes.
• Large footprint results in
significant property impacts.
Alternative 2:
Signalized Intersection
Alternative 3:
No Changes
Key Points:
• Connecting side street and
turning traffic volumes do
not warrant a signalized
intersection at this location.
Key Points:
• Existing pedestrian crossing
signal maintained, but relocated
to north side of Beaufort Street.
• Bus bay to be located between
Beaufort Street and Wharnclife
Road North.
• Preferred
6. Pre-screening: Intersection Improvements
Alternative 1: Permanent track diversion
• Permanent 30.0m span constructed on a new track alignment
south of the existing track.
• Existing bridge would be removed.
• No road closure expected.
Alternative 2: Temporary track diversion
• Temporary embankment and track diversion constructed south of
the existing track.
• Complete road closure required.
• Permanent 30.0m span constructed on existing track alignment.
• Existing bridge would be removed.
Alternative 3: Temporary track diversion and temporary bridge
• Temporary bridge and track diversion constructed south of the
existing track.
• Permanent 30.0m span constructed on existing track alignment.
• Existing bridge would be removed.
• Shorter duration road closure expected.
• Preferred
Alternative 4: “Top Down” rapid bridge construction
• Permanent 50.0m span constructed on existing track alignment.
• Existing bridge and abutments would be removed.
• Temporary embankments required.
• No road closure expected.
7. Pre-screening: CP Rail Diversion
Four (4) alternatives were considered to widen the CP Rail subway on Wharncliffe Road North at Saunby Street:
Preferred Alternative - Temporary Diversion and Bridge
• A temporary structure south of the existing structure will be
used to divert train traffic until construction of the new
structure is completed.
• The detour length for the track will be approximately 600m,
from Gunn Street to west of Wharncliffe Road North.
• Construction of the new bridge will take approximately
three (3) years, including track diversion/ temporary
bridge construction, new bridge construction, and track
diversion removal.
• Two (2) lanes of vehicular traffic will remain open
during rail construction. Temporary, shorter duration
road closures will be necessary. Duration to be
confirmed later.

8. Preferred: CP Rail Diversion
Alternative 1: Structural Steel (Preferred)
• A new CP Rail overhead structure will be
constructed to accommodate the proposed wider
Wharncliffe Road North right-of-way.
• The preferred crossing is a single span steel
plate girder structure with a span length of 30 m.
• The bridge will consist of two steel plate girders
supported on reinforced concrete abutments and
founded on spread footings.
Three (3) alternatives were considered to widen the CP Rail subway on Wharncliffe Road North at Saunby Street:

Alternative 2: Reinforced Concrete
Alternative 3: Precast Pre-stressed Concrete Girders

Single Left Turn Lane
• Improves existing level of service
• Narrower road cross section
• Reduced impacts to properties
• Allows for greater flexibility in cross section
elements
• Preferred
Double Left Turn Lane
• Increased road cross section width due to
additional lane and median requirements
• Significant property and building impacts
• Requires dedicated signal cycle for turning
traffic movements
• Pedestrian movements are more difficult due
to widened roads

16. Streetscape Design
• Oxford Street was identified in the Transportation
Master Plan (2030) as a Rapid Transit (RT) corridor.
Improvements include road widening from 4 to 6 lanes.
• A concurrent Class EA study is underway to determine
routing for the proposed Rapid Transit system.
• Proposed routing for the RT system will impact the
Wharncliffe Road North/Oxford Street intersection.
• As a result, this Environmental Assessment must have
regard for potential transit priority initiatives. * to be confirmed in the Shift Rapid Transit Municipal Class Environmental
Assessment
Transit Priority Considerations*:
• The Oxford Street/Wharncliffe Road intersection is
considered a ‘transit priority’ intersection, and will
accommodate future rapid transit demands.
• Right turn lanes/queue jump lanes, complete with
transit priority signal adjustments, on eastbound and
westbound Oxford Street approaches would improve
transit operations.
Recommended Rapid Transit Network (TMP 2030)
17. Transit Priority
18. Detour Plan
Recommended Detour Routes • Road closures will require detouring of traffic.
• Traffic to be detoured to alternative arterial roads, including
Richmond Street and Wonderland Road, during any short or longer
term road closures.
• Local residents and businesses will have access at all times.
• Emergency vehicle and pedestrian access will remain available at
all times.
