    • Preliminary Construction & Traffic Planning Intro to Shop Local/Shop Eglinton Initiative June 27, 2012
    • Agenda• Introductions• Project Update• Preliminary Crosstown Construction & Traffic Planning Overview – Tunnelling Process – Stations – Allen Road• Shop Eglinton, Shop Local Initiative• Q&A, Discussion and Next Steps 7/3/2012 Preliminary Construction Planning
    • The Crosstown - 2012 • 60% faster than current bus routes • 7 minutes from Eglinton West Station (AllenFinal 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) Preliminary Construction Plan
    • 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 Preliminary Construction Plan
    • 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 Preliminary Construction Plan 6
    • Eglinton at Bathurst (looking west) Preliminary Construction Plan 7
    • Eglinton West Station Preliminary Construction Plan 8
    • Looking east from Oakwood Preliminary Construction Plan 9
    • 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 Preliminary Construction Plan
    • West Launch Shaft Keelesdale Park near Black Creek DriveLaunch Shaft• 60m long• 20m wide• 16m deep Preliminary Construction Plan
    • 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” Preliminary Construction Plan
    • Jet Grouting - Headwalls Typical Rig Jet Grouting Process2–3m Diameter Jet GroutFormed Soilcrete Columns Preliminary Construction Plan
    • 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 Preliminary Construction Plan
    • Utility Relocation Preliminary Construction Plan

    • 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 Preliminary Construction Plan
    • 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 Preliminary Construction Plan
    • 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. Preliminary Construction Plan
    • 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 Preliminary Construction Plan
    • 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 Preliminary Construction Plan
    • 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 Preliminary Construction Plan
    • 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 Preliminary Construction Plan
    • 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 tunnel-specific construction by approximately 1 year and allow full project completion by 2020• 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 Preliminary Construction Plan
    • Tunnel Launch ShaftSheppard Subway Example at Leslie Preliminary Construction Plan
    • 13 Division – Working with PoliceTemporary Property Requirements • 5 metre area between sidewalk and 13 Division building • Utility construction area • Temporary sidewalk • Tree removals are unavoidable • Sign removal/ relocation • Tiebacks Preliminary Construction Plan
    • 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 Preliminary Construction Plan
    • Temporary Local Road Closures at Eglinton AvenueTemporary closures at Eglinton intersections with some local streets willunfortunately be required during different phases of tunnel construction to safelycomplete work:• Yarrow Road (2012-2013 - 7 weeks)• Kane Avenue (2013 - 5 weeks)• Little Boulevard (2013 – 4 days)• Strathearn Road (2013 - 11 Weeks)• Flanders Road (2013 - 11 Weeks)• Peveril Hill North Road (2013 - 9 Weeks)• Chaplin Crescent Southbound Thru & Left (2013 - 9 Weeks)• Latimer Avenue (2013 - 9 Weeks)• Highbourne Road (2014 - 9 Weeks)• Maxwell Avenue (2015 - 17 Weeks) Preliminary Construction Plan
