It was sent to the scrap yard, with a bit of maintenance it could have been started up rather then buying a new one.

The tunnel boring machines for the Eglinton Crosstown were purpose-built, meaning that once their journey was complete, they reached end-of-life and cannot be reused.

We understand that residents and businesses will want specific details about benefits and impacts to their properties and neighbourhoods. Traction power substation locations are generally evenly distributed along the alignment to provide electrical power to the overall system. We expect to have more detailed information to share in the coming months, including location of traction power substations, when we will have completed further design work.

Is the line going to be located directly underneath the roadway or offset from the road for the tunnel section? Side platforms and island platforms? The arrangement needs to ensure a direct elevator from the platform to the street is possible, without taking multiple elevators.

The alignment and station locations put forward in the Initial Business Case considers a number of factors, including improving the customer experience, increasing access to transit, maximizing ridership, achieving travel time savings and creating better access to jobs. These criteria are balanced by cost and other community considerations. We expect to have more detailed information to share in the coming months, when we will have completed further design work.

The LRT is expected to have ATC in the grade-separated section. Any at-grade crossings between Martin Grove station and Renforth station will limit the number of trains that can run west of Martin Grove, to the Renforth transit hub which is an important node for airport employment and connections to Miway and GO buses. I would suggest the line turn at-grade west of Renforth Road and have 2 island platforms with a middle track for short-turns for Renforth station. Renforth station will also be where operation mode between driver and ATC is changed.

We acknowledge that there have been many discussions on how to deliver rapid transit along Eglinton West over the years, and now we are moving forward with a solution. The 2019 budget announcement identified an alignment for the extension that would be mostly underground. There will be an underground connection to the Eglinton Crosstown LRT at Mt Dennis. The area between Scarlett Road and Jane Street is in an identified flood plain zone.  Tunnelling would require building underneath three flood-prone waterways and present significant technical challenges to building and operating the line. Elevating the Eglinton Crosstown West Extension between Scarlett Road and Jane Street eliminates these challenges and will help to prevent potential service disruptions along the corridor during times of heavy rain and flooding.

With the planned construction of 882 residential units in a high rise development at the north east corner of The East Mall and Eglinton, I am wondering why Metrolinx is not reconsidering its decision to add a stop at The East Mall. At the time the decision was made to cut this stop, this development was not under consideration. Adding a stop here would reduce potential congestion along The East Mall and boost ridership alleviating pressure on the subway line and other surface routes.

I live near Martin Grove and Eglinton. I would appreciate you send me any visual aids to help me understand what the station will look like when it is done. my email is [email protected]

I also have a concern that traffic at the intersection is already not good with long lines and almost gridlock at rush hours. Please consider options for opening new lanes to maintain throughput if there are going to be lane closures. There is plenty of room available because there are large setbacks.

The Eglinton Crosstown West Extension is still in the early stages of the project, so we don’t have the exact location of stations yet.

We know that residents have concerns about the potential impacts of construction in their community. As we proceed through the planning and design process, we will be assessing and managing traffic impacts along the corridor in collaboration with our community partners. Metrolinx has a number of measures it can take to reduce and manage impacts to residents and communities, both during and after construction, which we will use whenever and wherever necessary.

The presentation indicates that the Bank of Nova Scotia building at 1151 Weston Road may potentially be directly impacted. What does that mean - demolished/removed/replaced?

Also, would any of the houses and/or businesses west of Weston Road (heading toward Jane Street) need to be expropriated?

Hi

The Government of Ontario has committed $4.7 billion toward the program as a whole and is seeking additional funding commitments from the federal government.

Metrolinx and Infrastructure Ontario will use a public-private partnership (P3) procurement model to ensure the Eglinton Crosstown West Extension is delivered efficiently and cost-effectively.

Lanterra Developments is planning a large condo community at 4000 Eglinton Avenue West (just east of Royal York Road). Are there any plans to build an underground tunnel and connect residents to and from the Royal York 'subway' stop? Similarly, would the existing condo at that specific intersection get access to an underground pathway to that station?

A zoning by-law amendment application for 1 Richview Road was filed a while ago with the City. The application proposed the construction of a 21-storey, 65 m high apartment building having 235 rental units. After reviewing the presentation slides, it appears that the elevated alignment just west of Scarlett Road will occupy the lands of the proposed apartment building. Is it safe to say that the zoning by-law amendment application for 1 Richview Road has now gone 'up in the air'?

The very first proposal by the TTC had the LRT run at grade through the community of Mount Dennis. This was met with great opposition by residents, with over 500 signatures on a petition (sent to local politicians) to put the line completely underground. Even the local newspaper wrote an article titled "Residents lobby to bury LRT through Mount Dennis".

Extending the Eglinton Crosstown LRT will make it easier for people in the GTA to get where they need to be each day, whether that’s work, home or anywhere in between.

We know that higher-order transit like this is transformative in so many ways. The Eglinton Crosstown West Extension will deliver significant benefits to the community in the form of better access to transit, shorter journeys across the city, better access to jobs, and less traffic on our roadways. It will support the creation of transit-oriented communities where people can live, work and play, contributing significantly to the housing supply across the GTA and creating a more vibrant economy.

There is plenty of room along Eglinton West for surface rail, which is much, much more cost effective. The plan to create subsurface tunnels and stations is incredibly wasteful.

Additionally, the further EA requirements from changing your plan create delays, when we really need more transit ASAP.

The 2019 budget announcement identified an alignment for the extension that would be mostly underground. The alignment moving forward for further study in the Preliminary Design Business Case provides an optimal trade-off between the ease of local access and the speed of travelling, and outperforms all other options in offering the best network connectivity and travel experience for people living and travelling along the corridor.

 

An addendum to the 2010 environmental assessment for the Eglinton Crosstown is currently underway to capture existing environmental conditions and changes to the alignment and station locations made since 2010. Results of these environmental studies will be shared as part of public engagement activities scheduled happening in Spring 2020.

To save costs, this portion past Jane St should be at grade. Otherwise, transit users are being treated differently than surface transit users. Also, there are people with claustrophobic issues and this extension would be useless. Eglinton ave itself is wide enough to have surface rapid transit as you could use the protected right of way for the previous Richview Expressway. So, there is NO logical reason to built this line underground.

Will the public have a real say in station locations at each road intersection? The locations of the cut and cover sites selected will have a real impact on how much the community suffers through construction for months or years. Planners should be compelled to examine/ publish multiple options and justify their choices. Open spaces available on the north or south side of Eglinton would suggest that stations can be constructed with limited disruption to road traffic. The current work on the Eglinton LRT through the city centre would seem to demonstrate a requirement to present lessons learned.

Eglinton and Martin Grove is one of the most congested intersections and roadway portions in the city as it is adjacent to the Centennial business park. Majority of business commuters currently live outside the city and must drive in and won't be taken off the road by taking the subway extension. Rathburn and Dixon are quite far away for diverting, Eglinton at the 427 underpass constantly comes to a complete halt. Very happy to see that the system will be underground and will hopefully not further burden this roadway, however, it's unacceptable in its current state. Will there be widening or roadway optimization on Eglinton between Renforth and Martin Grove to mitigate the impact of the extension construction and reduce the gridlock? It can take over 45mins in traffic to travel this 3km(!) stretch of Eglinton.

With regard to your question about transit-supportive development, Metrolinx and Infrastructure Ontario have established a Transit Oriented Communities (TOC) team, using our combined expertise in transit delivery, land development and commercial transactions, to deliver TOC at new and existing transit stations on behalf of the Province. As we move forward, we will work closely with our municipal partners to integrate this type of development, which is designed to increase transit ridership and reduce traffic congestion, increase housing supply and jobs with access to transit, encourage complete communities, and allow the Province to maximize transit investment while reducing tax payer burden.

The Eglinton Crosstown West Extension will provide new, convenient connections along a presently rapid transit-deprived corridor with a faster and more reliable service — making it easier for people and businesses along the corridor to connect, invest, and innovate.

Although the Eglinton Crosstown West Extension will not intersect directly with the Hurontario LRT, you’ll be able to connect to both lines on GO and MiWay bus services via a planned connection to the Mississauga Transitway at Renforth Drive, in addition to the connections to UP Express and Kitchener Line GO train service at Mount Dennis and TTC bus services at transit stops in Toronto.

The TTC currently offers a number of bus routes for those looking to travel between Sheppard West and Sheppard Yonge stations. You can find out more about service and schedules for these routes on the TTC website

We recognize the need to deliver more transit quickly and safely, and we remain committed to doing so. Planning, design and construction work is continuing on all our projects to ensure we’re on track to deliver much-needed transit relief while creating jobs and stimulating the economy.

A Request for Qualifications (RFQ) for tunnelling was released in March and closed at the end of May. After discussions with the market and after advancing our own design/planning investigations, we determined that this work could begin to keep the project moving forward as fast as possible.

The RFQ is the first step in the procurement process to identify project teams that have the required design and construction capability and experience, and the financial capacity to undertake projects of this size and complexity. At this time, we’re anticipating that we’ll break ground on the tunnel launch shaft by next spring or summer.

Has Metrolinx done a direct comparison of the costs and benefits of TBM construction versus cut-and-cover construction for the entire length of this line? If so, will this be made public?
TBM Tunnelling has proved extremely disruptive during the Crosstown project, its deeper station and access shafts take longer to excavate and construct. Construction forces/equipment have been on site for years. No part of Eglinton has been spared. While TBM has been claimed to be less intrusive than cut and cover, that simply has not been the case on Eglinton.
Cut and cover represents the opportunity to shorten project execution, and lower the impact on the surface street. It may be cheaper.
Before any further use of TBMs is considered, Metrolinx should justify its construction method in an objective and fact based manner.

Metrolinx and Infrastructure Ontario are working closely together to ensure we deliver this important project in the best possible way, both during construction and beyond. The experts on both teams will draw on their extensive experience in planning and building complex infrastructure projects under a public-private partnership (P3) procurement model to ensure the Eglinton Crosstown West Extension is delivered efficiently and cost-effectively.

As noted in the recently-released Environmental Project Report (EPR) addendum, the underground alignment will be constructed using a Tunnel Boring Machine (TBM) between stations and a cut-and-cover method at stations and portal locations.

Tunnelling is just one phase of the project, and separate contracts will be issued in the future for the rest of the work, which includes building the stations, fitting out the tunnel and installing and commissioning the systems to put the line in service.

There appears to be a significant amount of space for an elevated alignment. A significant portion of the Ontario Line will be elevated to lower costs and result in faster completion. Many metro areas e.g. Vancouver, San Francisco Bay have and are building elevated rapid transit lines for those reasons.

Both the Ontario Line and the Eglinton Crosstown West Extension projects feature a mix of at-grade, elevated and underground elements. Decisions on alignments take into account a number of factors, including costs, integration with other transit, community impacts, deliverability and operations, and topography, which are unique to each project. The alignment option we are moving forward from the Initial Business Case provides an optimal trade-off between the ease of local access and the speed of travelling, and outperforms all other options examined in the business case in terms of offering the best network connectivity and travel experience for people living and travelling along the corridor.

Most of the road between scarlett and martin grove is pretty wide and is enough to accommodate the LRT tracks and stations, not to mention making the road safer (there are too many speeders on eglinton going well beyond the speed limits). It only makes sense in that regard, it'll save plenty of money on tunnel boring machines and station construction.
