Welcome to the Online Consultation Preliminary Construction & Traffic Planning Intro to Shop Local/Shop Eglinton Initiative Please review the presentation and complete the survey by July 11, 2012.
Preliminary Construction Planning
1 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 (west side of Allen southbound)
Preliminary Construction Planning
2 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 Planning
3 The Crosstown – 2012 *Final number and location of stations subject to Provincial review
• 60% faster than current bus routes • 15 minutes from Keele to Yonge
Preliminary Construction Planning
4 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

8 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 Planning
9 West Launch Shaft Keelesdale Park near Black Creek Drive Launch Shaft Eglinton Ave • 60m Long • 20m wide • 16m deep
Preliminary Construction Planning
10 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. These are large pits where tunnelling machines are first lowered for assembly and then extracted from the ground. • The tunnel machines are launched from Keelesdale Park (just west of Keele Street) and tunnel eastward through the station “headwalls”
Preliminary Construction Planning
11 Tunnel Construction Overview Continued • To ensure subway service is maintained throughout construction, tunnelling machines are removed from a pit 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

23 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
Preliminary Construction Planning
24 West Tunnelling – Keele Street to Yonge Street Traffic Management Overview
Preliminary Construction Planning
25 Existing Conditions on Eglinton • Rush Hours : 7am to 9am & 4pm to 6pm • Most sections of Eglinton between Keele and Allen have one lane in each direction for general traffic inrush hours • Between Allen and Yonge, most sections have two lanes in each direction available for general traffic inrush hours • In most sections during rush hours, the curb lane is for buses 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 Planning
26 Existing Conditions Eglinton Avenue Dufferin to Chaplin • External traffic represents45% of the auto trips (AM peak) • 45% of traffic has an origin and destination outside the area & use Eglinton as a traffic corridor • PM peak period is similar, 42% external, 58% local
Preliminary Construction Planning
27 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 Planning
28 Transit Services during Tunnel Construction • Pedestrian and bus access to Eglinton West and Eglinton Stations will remain open • No major change to existing bus routes • Local bus route detours may be required for key construction activities for tunneling • TTC buses along Eglinton will be monitored and additional vehicles added as needed to respond to changes in traffic conditions
Preliminary Construction Planning
29 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 Planning
30 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 Planning
33 Allen Road Area • Tunnelling under Eglinton West Station carries risk to subway operations • Detailed Traffic management plans to 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 • Potential short duration Eastbound to Northbound left turn prohibitions from Eglinton onto Allen Road for decking installation at ramp
Preliminary Construction Planning
34 Allen Road Proposed One Year Closure in 2014 to Northbound Access at Eglinton • Potential closure of northbound access to Allen Road at Eglinton to expedite tunnelling • Closure projected to reduce construction by approximately one year • Northbound Allen would remain open north of Eglinton • 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
