7/3/2012 Preliminary Construction Planning

The Crosstown - 2012

• 60% faster than current
bus routes
• 7 minutes from Eglinton
West Station (Allen
Final number and location of stations subject to Provincial review Road) to Yonge Street

Preliminary Construction Plan

Update

• The first Tunnel Contract (Keele St to Yonge St) will be awarded this
summer

• Detailed traffic plans will be developed after the contract is awarded

• Additional public meetings in Fall 2012 to discuss detailed construction
plans for the first tunnelling contract

• The earliest utility work could begin on Eglinton in the vicinity of Allen
Road is late 2012 (Eglinton @ Allen southbound & Keele Street)


Tunnel Construction Principles

• Package contracts to coordinate all work under same umbrella
(utilities, city, transit)

• Maintain a minimum of one lane eastbound and westbound on
Eglinton in construction zones

• Access to buildings from Eglinton remains open

• Only propose road closures if required for safety reasons or to
provide exceptional time savings and reduction to long term
disruption


Eglinton Bus Ridership
• Eglinton 32 & 34 buses carry 68,500 riders every
weekday

• Transfers required at Eglinton West and Eglinton
Stations (Allen & Yonge)

• Eglinton has amongst the
highest ridership of all
bus routes

Crosstown Construction Update

• Tunnel preparation work at
Black Creek and Eglinton in
Keelesdale Park

• Piling rigs are building concrete
support walls for the future west
tunnel launch shaft

• The west launch shaft will
enable tunnelling works in late
2012 towards Allen Road


West Launch Shaft
Keelesdale Park near Black Creek Drive

Launch Shaft
• 60m long
• 20m wide
• 16m deep


Tunnel Construction Overview
• Relocate utilities at major intersections to maintain services (gas, water, cable)

• Construct “headwalls” (support walls formed by a series of concrete columns) at east
and west ends of each future station location
- 4-5 months per station location
- Process called “Jet Grouting” when soil conditions allow – 3-4 months

• Concurrently, construct Tunnel launch and extraction shafts

• The tunnel machines are launched from Keelesdale Park (just west of Keele Street)
and tunnel eastward through the station “headwalls”


Jet Grouting - Headwalls

Typical Rig

Jet Grouting Process

2–3m Diameter Jet Grout
Formed Soilcrete Columns


Tunnel Construction Overview Continued

• To maintain Subway Service throughout construction, tunnelling machines are
extracted at the west side of Allen Road on Eglinton and re-launched from a new pit
on the east side of Allen Road on Eglinton

• Tunnelling proceeds to Yonge Street, and a second extraction pit is built to remove and
re-furbish the machines before they reach Eglinton Station

• Following this tunnelling work, the Crosstown Stations between Keele and Yonge will
be constructed

• Stations will each take approximately 4 years to construct

Soil removal for Tunnelling

• 1 165 000 cubic
metres of soil to be
removed during
tunnelling

• Enough to fill the ACC
rink higher than the
CN Tower


West Tunnelling – Keele Street to Yonge Street

Preliminary Traffic Management Overview

Existing Conditions on Eglinton

• Rush Hours : 7am to 9am & 4pm to 6pm

• Most sections from Keele to Allen have one lane in each direction for
general traffic in rush hours

• Most sections from Allen to Yonge have two lanes in each direction
available for general traffic in rush hours

• In most sections during rush hours, the curb lane is for buses/taxis only

• Outside of rush hours, the curb lanes are used for on-street parking,
generally leaving one lane per direction for moving traffic


Traffic Origin
Eglinton Avenue Dufferin to Chaplin

• External traffic represents 45% of the auto trips (AM peak)

• 45% of traffic has an origin and destination outside the area & use Eglinton
as a traffic corridor in AM peak

• PM peak period is similar, 42% external, 58% local


During Tunnel Construction

• One lane of traffic available on Eglinton both EB and WB all-day in
active construction zones. Buses and general traffic will share this
lane.

• Advance warning signs will be placed in the vicinity of the corridor.
Changeable Message Signs and Static Signs.


Transit Services during Tunnel Construction

• Pedestrian and bus access to Eglinton West and Eglinton Stations will
remain open
• Some local bus route detours may be required for key tunnelling
activities (e.g. tunnel extraction shaft near Duplex Avenue)
• Eglinton buses will be monitored and additional buses added as
needed to respond to changes in traffic conditions


Parking

• Currently, 3 hour paid parking is available on Eglinton Avenue West
outside of weekday rush hours.

• In order to provide space for construction work, some of these spaces
will be unavailable

• One-hour parking on some local roads will be extended to 3 hours, only
while construction is impacting parking availability on Eglinton Avenue

• Parking on local roads will be enforced to discourage long-term
parking and will be closely monitored by Toronto Police Services
Parking Enforcement


Pedestrians/ Cyclists
• Front door access to Eglinton Avenue buildings maintained

• Minimum 1.5 metre sidewalk widths

• Some temporary closures of sections of sidewalk required. Where
necessary, crossings will be available at traffic signals. One side open at
all times.

• Bike lanes not currently provided on Eglinton

• During construction, cyclists will continue to share general traffic lanes

• Where space is available, wider lanes provided to accommodate all users


Allen Road Area

• Detailed Traffic management plans will be developed upon award of tunnel
contract and presented at Fall 2012 follow-up meeting
• 2013 – Potential for occasional, off peak (overnight) Southbound Right
Turn prohibitions from Allen to Eglinton for utility relocations at Extraction
Shaft
• 2013 - Potential short duration Eastbound to Northbound left turn
prohibitions from Eglinton onto Allen Road for decking installation at ramp


Allen Road
Proposed Closure to Northbound Access at
Eglinton in 2014
• Potential closure of northbound access to Allen Road at Eglinton to
expedite tunnelling

• Closure projected to reduce construction by approximately one year

• Northbound Allen access would remain open at Lawrence

• Closure would give contractor enough space for construction staging and
movement of 150 trucks per day directly onto Allen Road

– All prohibitions at Allen Road require City Council approval
– Anticipated report timing is FALL 2012 Public Works Committee/City
Council


Tunnel Launch Shaft
Sheppard Subway Example at Leslie


13 Division – Working with Police
Temporary Property Requirements
• 5 metre area between
sidewalk and 13 Division
building
• Utility construction area
• Temporary sidewalk
• Tree removals are
unavoidable
• Sign removal/ relocation
• Tiebacks


Cross Passages - 2014
• Cross passages are used for emergency evacuation of the tunnels and for
access between the tunnels for maintenance

• Constructed by hand mining between the two tunnels

• Area needed on road for pumping equipment to dewater the area where the
mining is conducted

• Bathurst to Yonge: Jet grouting is required. Street occupation similar to station
headwalls

• Impact = 2 -3 months per location

• 1 lane per direction


Temporary Local Road Closures at Eglinton Avenue
Temporary closures at Eglinton intersections with some local streets will
unfortunately be required during different phases of tunnel construction to safely
complete work:

• Yarrow Road (2012-2013 - 7 weeks)
• Kane Avenue (2013 - 5 weeks)
• Little Boulevard (2013 – 4 days)
