March to June 2021
The O-Train East Extension is one of the three major extensions to Ottawa’s light rail transit system. The extension will add over 12 km of new rail and 5 new stations (Montreal, Jeanne d’Arc, Convent Glen, Place d’Orléans, and Trim) between Blair Road and Trim Road. The LRT will travel predominantly within the median of Highway 174.In 2021, heavy construction will take place throughout the east alignment as crews build rail, pedestrian and road bridges, new highway lanes, the rail guideway (dedicated rail line) and begin station construction. While it is exciting to see progress on the LRT project, some of these activities may cause disruptions for area residents, including intermittent night work, traffic detours, site lighting or additional construction vehicles in the area. This notice provides an overview of upcoming activities along the O-Train East LRT project alignment, as well as the expected community impacts including hours of work, noise from crews and equipment, pedestrian, and vehicle mobility, etc.
Blair Station to 174 Median Rail Bridge
Work continues to progress on the Blair Station to 174 Median Rail Bridge, 800 metres east of the OR174 Blair Road Interchange. In April, girders (horizontal supports for the bridge) will be laid on top of the columns, followed by the installation of decking. The Blair Station to 174 Median Rail Bridge structure will be completed in the Summer 2021, with track work to follow.
Blair Road to Montreal Road
Last year, new eastbound and westbound highway traffic lanes were constructed on the south side of the 174, between Blair Road and Montreal Road to create space for the LRT guideway. Crews and equipment in the area, are now removing the asphalt and concrete from the old highway in the median. This work is occurring daytime and overnight until September.
In January, crews and equipment began building a new bridge within the median of OR174 across Montreal Road, at the Highway 174 Interchange. This new bridge is required to create enough space for the LRT guideway and the new Montréal Station. Through March, construction activities for the bridge include excavation and drilling caissons – part of the bridge foundations. From March through June, activities will include the completion of the bridge’s columns, abutments, and pier caps. This will require lane reductions along Montreal Road.
Jeanne d’Arc Boulevard
In November 2020, crews and equipment began work to modify the access to Jeanne d’Arc on-ramps at OR174. This is required to create safer connections for pedestrians and cyclists on the Jeanne d’Arc bridge. While this work continues, there will also be on-going electrical and utility work required prior to the construction of the new Jeanne d’Arc LRT station, beginning in May 2021. In addition, work on the guideway including the installation of drainage in the median between Sir George Etienne Parkway to Orléans Boulevard Overpass began in February. This work will continue throughout the year.
Work continues at Orléans Boulevard, north and south of the 174, to relocate utilities, including a watermain, storm and sanitary sewer and gas line. On the west side of Orléans Boulevard, a culvert to improve drainage will be installed. This work will continue through June 2021.
Beginning in April, significant construction activities will begin near Place d’Orléans with rock excavation. Hoe-ramming will be required to break up the bedrock. Excavation is also required to realign the 174 north and south of the existing highway to move traffic to make room for the work to build the guideway and the Place d’Orléans Station. There will be further rock excavation required for the guideway and station. The rock breaking and excavation work will continue through July 2021. Utilities work, such as drainage installation, willcontinue through the Spring this year.
A new watermain and sewer line is being installed to service the future Trim LRT Station and busfacility. At the same time, construction of a new eastbound off-ramp, and a future realignment of TrimRoad will begin with topsoil removal, embankment, and granular placement. A road closure at Dairy Drive, from the traffic circle of Trim Road, to the Agropur Cooperative began in February. The Agropur Cooperative will remain accessible via Old Montreal Road (east of Trim Road). Closure of South Frontage, between the OC Transpo Park and Ride / Trim Station and Dairy Drive will continue until July 2021. The OC Transpo Park and Ride and Trim Station access to southbound Trim Road will be maintained via the construction of a detour route. These activities are required to create a cul de sac which will facilitate the work for the future site of Trim Station.
Typically, most work is scheduled to occur from 7:00 am to 6:00 pm, Monday to Friday. There will be requirements for overnight work across the entire corridor, and some intermittent weekend work, throughout the year.
Noise and vibration from trucks and heavy equipment is expected.
Site lighting for overnight work will be required.
All pedestrian, cycling, bus, and vehicular movements will generally be maintained during construction apart from highway ramp closures. Pedestrians and cyclists should use extra caution when localized detours are in place.
Motorists should adhere to detours, traffic control signage, posted speed limits, and use extra caution as traffic patterns change. Motorists should use caution and allow for added travel time when moving through active construction corridors.
This notice provides an overview of activities expected to occur until June 2021. Specific timing of activities, including road closures or detours, overnight activities or other major works, will be communicated in advance via the Stage 2 project e-newsletter.
