Here are all the construction projects the City of Ottawa has planned for the summer and fall

Ottawa is spending $702 million on upcoming infratucture projects

Ottawa’s $702 million allotted for infrastrucure for 2022 means another busy summer of construction

OTTAWA, June 8, 2022 – The saying that there are two seasons in Ottawa: winter and construction season, will certainly hold true again this year. And as the area is dealing with the ravages of last month’s storm, the City of Ottawa says it will invest approximately $702 million in city infrastructure in order to continue to provide vital services to residents, businesses and visitors – everything from safe drinking water, to the roads, bridges, sidewalks, pathways used to get around the city, to the stormwater ponds collecting rainwater, to the underground pipe network effectively transporting wastewater, to the City’s sewage treatment facility.

Keep reading the City’s news release to learn how this year’s Ottawa construction projects may affect you, or how you get around in our nation’s capital this summer.

Cycling in the city

The number of people cycling continues to grow every year in Ottawa. The City’s cycling vision is to develop a citywide, connected network of cycling facilities for all types and ages of cyclists to help establish Ottawa as one of the best cycling networks in North America.

When construction for the Stage 2 Light Rail Transit (LRT) project is complete, it will deliver approximately 25 kilometres of new active transportation facilities for both pedestrians and cyclists.

Upon its completion, the enhanced cycling facilities for the Laurier Avenue improvements (Nicholas to Waller streets) project will separate cyclists from mixed traffic, greatly improving the level of comfort and safety for all users. This project will integrate cycling connections with the Mackenzie King Bridge via the Rideau Canal Eastern Pathway. It will also include safety measures such as separated signal phasing and protected intersection crossings.

Cycle tracks will also be built this year on other projects, including the Montreal Road revitalization, Albert, Queen, Slater, Bronson reconstruction, Dovercourt Avenue sidewalk and bike lanes implementation and more.

Stage 2 LRT (O-Train construction)

Work is well underway on the Stage 2 LRT project, transforming our city’s future transit system. This year, the City will continue construction to extend the O-Train to more communities farther east, west and south.

O-Train East

The O-Train East Extension will link Blair Station to Trim Road. This work will add 12 kilometres of rail and five new stations to the O-Train network at Montreal Road, Jeanne d’Arc Boulevard, Convent Glen, Place d’Orléans and Trim Road.

This year, crews will continue work in the Highway 174 median as they install track, connecting five new stations. Station construction has started on all new stations, and residents will see them take shape throughout the year. Crews will also install three new pedestrian bridges to enhance connectivity to the O-Train network.

O-Train West

The O-Train West Line will extend from Westboro Station to Moodie Drive and Algonquin Station. The extension will add over 15 kilometres of new rail and 11 new stations. It also includes a light maintenance and storage facility, 10 new bridges, 14 rehabilitated bridges and two cut and cover tunnels.

This year, cut and cover tunnel construction of the Parkway and Connaught tunnels will continue, including excavation starting the cover work, which is a major milestone of the project.

O-Train South

The O-Train South Extension will run 12 kilometres through 11 stations, both new and existing, from Bayview Station to Limebank Road, and include 12 kilometres of new rail. An additional Airport Link will run from South Keys to the Ottawa International Airport.

This year will see station construction advance, more rail installed and the testing and commissioning of the new Stadler FLIRT vehicles!
