  • 3. 3 Eglinton Crosstown LRT  Project  $4.9 B (2010$), funded by the Province of Ontario  19 kilometres east-west LRT from Kennedy to Jane/Black Creek, including 10 kilometres of tunnel  Connections to Yonge-University-Spadina Subway, Scarborough RT and GO Stouffville  Up to 26 stations
  • 4. 4 East Tunnel Construction Timeline  At future station locations underground structures (emergency exits, cross passages) utility relocation and headwall installation is expected to last approximately six to eight months on average  Emergency Exits at Donlea/Hanna and at Petman Avenue are expected to take up to 24 months to construct  The deep excavation at Brentcliffe is expected to take up to 12 months to construct  Tunnelling activities to Yonge are expected to be completed by summer 2016  Following the completion of tunnelling works, the site will be turned over to the Metrolinx station contractor
  • 5. 5 Tunnel Boring Machine  The construction of new tunnels under Eglinton Avenue is done by tunnel boring machines (TBMs).  Each TBM moves forward by pushing off against concrete segments.  The operator advances the machine as soil is removed from the TBM face through a conveyor system.  The launch pit remains active for removal of muck/spoils.  Expected to arrive on site mid-2014 and be constructed on site alongside the completion of the launch shaft.
  • 6. 6 Assembly of Tunnel Boring Machines
  • 7. 7 East Tunnels Launch Shaft  To Brentcliffe To Leslie 
  • 8. 8 Launch Shaft
  • 9. 9 Sequence of Tunnel Drive
  • 10. 10 Tunnel Drive Works 2014  Headwalls are temporary support walls for future excavation of the LRT stations.  Made of concrete and installed to the depth of the future track level  Two methods of installation used: Secant Pile Walls, Jet Grout  Machinery including drill rigs, grout tanks, diggers and other equipment
  • 11. 11 Tunnel Drive Works 2014 Secant pile wall : formed by intersecting concrete piles Jet grout wall : uses engineered grout to form wall on site
  • 12. 12 TBM Launch- Vicinity of Brentcliffe Road and Eglinton  Launch Shaft: a deep excavation located just east of Brentcliffe where two tunnel boring machines will be launched toward Yonge  Utility relocation will occur before excavation begins  Concrete temporary support walls will form the foundation of the shaft  Work will start on the north side of Eglinton Avenue. Traffic will be shifted according to phases of the work.
  • 13. 13 Utility Relocations  Construction of the headwalls and shafts requires that some utilities be moved safely out of the way  Depending on site conditions: gas, hydro, water mains, sewers, lighting and telephone and cable lines may be relocated to allow for construction  In the vicinity of the launch and extraction shafts Metrolinx is co- ordinating with Bell, Enbridge, Toronto Water and Toronto Hydro, Cogeco regarding required relocations  In most cases utility relocations will be undertaken by Metrolinx contractor  Enbridge will coordinate works with Metrolinx
  • 14. 14 Emergency Exit Buildings  Required where station platforms are more than 762 metres apart  Required between the following stations:  Mount Pleasant/ Bayview  Bayview/ Laird  Constructed by Tunnels contractors
  • 15. 15 Emergency Exit Buildings and Cross Passages Hannah Road Petman Avenue
  • 16. 16 Approach to Traffic Management  Maintain a minimum of one lane eastbound and westbound on Eglinton in construction work zones  Buses and general traffic will share this lane  Additional lanes will be provided if space allows  Metrolinx will work with City of Toronto Transportation, local elected officials and neighbours to monitor local traffic  Signal timing may be modified and turning restrictions may be added or relaxed
  • 17. 17 Traffic Lane Reductions
  • 18. 18 Transit Services during Tunnel Construction  Both eastbound and westbound TTC stops in the affected area may be shifted and relocated for the safety of transit riders  Watch for TTC posted signs indicating the adjusted stop locations
  • 19. 19 Pedestrians  In the construction zone for temporary sidewalks or existing sidewalks the goal is to maintain 1.5 metre sidewalk widths wherever possible  Access to properties from sidewalks should be maintained  Some sections of sidewalk may be closed and crossings will be available at traffic signals  Please take care when travelling near construction. Watch for additional signage directing pedestrians
