CROSSTOWN LRT WHO IS METROLINX? Construction of the Eglinton Crosstown LRT Line Background • In September 2008, Metrolinx launched a regional transportation plan – a 25-year, $50 billion plan -- to coordinate and integrate transportation and transit in the Greater Toronto Area • In 2010, City of Toronto approved the project to build the Eglinton Crosstown from Weston Road in the west to Kennedy Station in the east. • Following a competitive process, Crosslinx Transit Solutions (CTS) was awarded a contract in July 2015 to design, build, finance, and maintain the Eglinton Crosstown Light Rail Transit (LRT). Project Players and Roles What Are We Building – a New Modern LRT • 15 underground stations and 10 surface stops – 9 km below ground and 10 km above ground • A maintenance and storage facility • A 19-kilometre route separated from regular traffic • Transit communications system • Links to 54 bus routes, three subway stations, GO Transit, and a new UP Express station Awaiting Safety First – Our #1 Priority feedback from Safety We train and direct staff to: • Always have a site specific safety plan and site specific emergency plan. • Ensure pre-work hazard assessments are complete and understood. • Ensure job hazards analyses are complete and understood. • Do everything possible to protect themselves, co-workers, and members of the public. • Stop work if the safety of themselves, co-workers and members of the public cannot be assured. • Identify and report unsafe behaviour and coach each other to make improvements. • Be prepared and equipped to work safely. Crosstown Design Approach Street Level – Contextual and An International Signature for Entrance – Bright & Secure Inviting Toronto Concourse – Simple & Pristine Concourse – Transparent & Open Platform – Spacious & Animated CTSD Ask designers what key features are Accessibility Ask for existing examples of other projects Station and Stops are designed to be universally accessible, including satisfaction of the Need better visuals AODA, applicable City of Toronto Guidelines, the OBC, and CSA Standards. Some of those features include: • Barrier‐free paths from the entrance level to the station platform level • Tactile warning strips and tactile walking surface indicators • Signage systems with tactile indicators • Passenger Assistance Intercoms (PAI) • Low floor Light Rail Vehicles (LRV) with designated wheelchair locations • Nominal gaps from platform edges to LRV entries • Automated visual and audible stop announcements • On-street and off-street paratransit passenger pick-ups and drop-offs Environment & Sustainability During Construction • Programs to minimize impact on wildlife, their habitats, watercourses and trees • Reduce impact on our community neighbours through the management of dust, noise and vibration • Sustainable construction practices, including active management of construction and demolition generated wastes, targeting 75% waste diversion from landfills; and off-site beneficial reuse of excess soil. Project Design Sustainability • Project wide application of Toronto • Fritted glazing (minimize bird Green Standard collisions) • LEED Certification at EMSF • Shielded exterior lighting (prevent off- • Bike parking for short- and long-term site light trespass) users • Sheltered waiting areas • Dedicated pedestrian routes • Energy efficiency – LED lighting, heat • High Solar Reflectance Index paving recovery systems • Green roofs • Landscaping – use of native, drought- • Water use conservation/efficiency tolerant plants and large trees How We’re Building the Crosstown: Construction Overview How We’re Building: Two Methods Cut-and-Cover Stations Mined Stations • An area the size of the station’s • Mining occurs from inside of the footprint is cut, a shallow area excavated entrances after the excavated, and steel piles, braces, and shoring is complete. Each tie-backs are installed. Decking is then underground area to be mined is placed over the excavation to allow divided into segments, and mined traffic to resume overhead. in sequence.

Support Works – Utilities Mitigation What to expect: Watermain Replacement • Water main replacement work will include trenching and removing and replacing pipes. • This work will occur on watermains on Eglinton Avenue West between Avenue Black Creek Drive and Keelesdale Drive. • Lane closures will be required for this work. At least one lane in each direction will be maintained. • Pedestrian access will be maintained. A public notice with additional details will be distributed prior to work beginning. LRT Tunnel Fit Out Tunnel Invert Pour: Key Milestones Tunnel Fit Out: Progress to Date • Concrete trucks deliver concrete every 30-60 minutes, depending on how far down the tunnel the work is occurring • Trucks park beside the shaft at Cedarvale (Allen Rd. and Eglinton), and unload 9 m3 of concrete into a large pipe, into one of two mini concrete trucks (4.5 m3 each) at the shaft floor. • The mini truck in the shaft then drives down the tunnel to the next section of tunnel to be inverted. • The first stage of concrete pour began in tunnel section 1 on April 4, 2017, and tunnel section 2 on April 17, 2017. • On average, crews complete a section approximately 80 metres in length of the concrete slab per day in each tunnel. Concrete Invert Pour - Concrete Delivery • Mini concrete trucks delivering concrete into tunnel. Concrete Invert Pour - Stage 1 • Concrete trucks deliver loose concrete to the work area • Loose concrete mix is used to fill the bottom of the tunnel • Tunnel Fit Out Crew flatten and smooth it Concrete Invert Pour – Stage 2 • Workers install welded mesh which functions like rebar to help reinforce the next layer of concrete • Higher strength concrete is poured to provide the flat track slab for the rail tracks • Workers spread the concrete, and a truss screed machine vibrates it into a perfectly level surface Tunnel Fit Out: What to expect in 2017 • Track work will begin at the Eglinton Maintenance and Storage Facility (EMSF) within the Vehicle Cleaning & Inspection Facility (VCIF) as early as summer 2017. • This track will be the spur line to the rail corridor that will deliver the light rail vehicles to the VCIF at the EMSF site • Mid to late in 2017, small portion of track installed in tunnel (TBD between the West Portal and Keelesdale Station) • This section of track will be the test section for the tunnel fit out. • Majority of track will be installed in the tunnels after the station box construction completion across the line Caledonia Station Aerial Rendering BUS LOOP STATION FUTURE BRIDGE CONNECTION* 90% design rendering *Bridge connection is not part of Crosstown LRT construction Caledonia Station Main Entrance FUTURE RETAIL SPACE 90% design rendering Caledonia Station Exterior Plaza SHELTERED BIKE PARKING 90% design rendering Caledonia Station Bus
