Highlights

  • Construction of two new stations and the extension of five station platforms on the existing Trillium Line to accommodate longer trains with additional capacity.
  • Four new stations along the new extension and two new stations along the 4-kilometre Airport Link.
  • Construction of a new Walkley Yard Maintenance and Storage Facility (MSF).
  • Delivery of new municipal infrastructure, including two new pedestrian bridges to improve connectivity along the alignment through multiuse pathways (MUPs).
  • Maintenance of both the existing Trillium Line and the extension for 27 years.

Extension Description

The Trillium Line extension includes eight new stations and sixteen additional kilometres of track from Greenboro to Limebank in Riverside South, with passing tracks at South Keys and double tracked south of Leitrim to Limebank Road. The proposed plan would essentially extend the City’s LRT reach to Limebank Road in Riverside South, bringing southern communities such as Manotick, Findlay Creek, Greely and Osgoode much closer to this high quality transit service. The overall alignment for the most part follows the existing CPR alignment up to Earl Armstrong Road where it curves west to Limebank Road.

The extension of the Trillium Line, new stations and structures for grade separation will allow for future conversion to twin-track electric LRT and will be built to accommodate the planned widening of both the Airport Parkway and Lester Road.

Bayview Station

Bayview Station is an existing transfer station on the Confederation Line and also serves as the north terminus station of the Trillium Line. The existing single-track Trillium Line station platform located on the lower level will remain in place and be extended to accommodate the new longer Trillium Line trains. A second track and platform will be provided on the east side of the alignment to allow the station to operate as a two-track station, creating enhanced operational flexibility.

The two platforms will be connected by a partially enclosed walkway to allow customers access to each platform from the station entrance to the Confederation Line without being completely exposed to the elements.

A new fare controlled entrance and plaza will be provided at the southern end of the western train platform extension. Located adjacent to the new entry, outside of the fare paid zone, a vertical circulation core consisting of two elevators and stairs will serve a new fully enclosed pedestrian bridge providing the public a safe, direct, and weather protected connection across the Trillium Line corridor connecting to the adjacent development on Albert Street.

Trinity Developments Inc. have agreed to fund this pedestrian bridge link from their future development at 900 Albert St., which will be implemented through the Stage 2 project.

Gladstone Station

Gladstone Station will be a new station located north of Gladstone Avenue. A singlefare paid entrance will be centred upon the alignment with a new station plaza integrated with the existing Gladstone Avenue Bridge. The public plaza design will include a mix zone near Gladstone Avenue to allow the mixing of pedestrians and cyclist utilizing the north-south MUP in a controlled manner, while the eastern edge of the public plaza will be separated from the north-south MUP with landscape and urban design elements to prevent the uncontrolled mixing of pedestrian and cyclists within in the plaza.

The station is being designed to protect for a second level to ensure overhead connections are supported from future development on both the east and west side of Gladstone Station.

Carling Station

Carling Station is an existing station located north of Carling Avenue served by an entrance from the adjacent MUP to the east of the alignment. A new elevator will be constructed to provide redundancy in serving the station entrance and platform. In addition to the new elevator, the existing elevator will be refurbished.

Design and construction of the station will not preclude a future double tracking, as well as a potential connection to the future hospital site, south of Carling Avenue.

Carleton Station

Carleton Station is an existing station with two platforms serving Carleton University and surrounding areas. The station is located between Campus Avenue and University Drive at the intersection of Campus Avenue and Library Road. It has two existing fare paid entrances, one from the east and one from the west. The existing fare control enclosure will remain. There will be a new additional pedestrian underpass structure north of the station platform to support Carleton University’s long-range development plans.

Taking advantage of the shut-down of Trillium Line and the major civil works planned, a new pedestrian tunnel segment will be constructed below the tracks for future connection to the university’s tunnel system, with the potential to provide direct weather-protected access to the station from the University’s tunnel network.

Mooney's Bay Station

Mooney’s Bay Station is an existing station located south of Heron Road, which will be served by one fare paid entrance located west of the alignment and accessible from the adjacent MUP. The existing fare control enclosure will remain. The station will be designed for any modifications needed at the entrance enclosure.

Airport Station

Airport Station is a new station at the Macdonald-Cartier International Airport and will represent the terminus of the Airport Link. It will be a new elevated station located adjacent to the airport departure roadway and the airport passenger terminal building. The entrance and lounge will be an extension of the airport terminal building and the station platform will be at the same elevation as the third level of the airport passenger terminal building.

The design of the station will be closely co-ordinated with the Airport Authority throughout design development as they will extend the existing airport passenger terminal structure to the station. The station, platform, guideway and guideway structures will be constructed to allow the Airport Authority to construct the airport passenger terminal expansion, including the entrance and lounge directly, together.
