Project description
The City of Ottawa is preparing to renew aging infrastructure and revitalize the right of way in the northern section of Old Ottawa East. The project area is predominantly bounded by the Rideau Canal to the west, King Edward Avenue to the north, Highway 417 to the east and Hawthorne Avenue to the south. A 160-metre section along Colonel By Drive/Echo Drive, which extends south of Hawthorne Avenue to Immaculata High School, is also included in the project limits. This work is being conducted to replace aging combined sewers with separate storm and sanitary sewers, replace sections of older watermains, and reconstruct the roadways, including the implementation of complete street features for the betterment of all road users in your community.
The Greenfield Avenue, Main Street, Hawthorne Avenue et al. reconstruction project is a multi-year project, with advanced construction work commencing in late summer 2021. In 2022, extensive underground and road construction work will occur, with expected completion in 2024, pending budget approvals. Once approvals are in place, the project team will communicate in advance of any updates to the schedule. Currently, the design work for this portion of the project is underway.

Project Timing
2021
The work in 2021 will include the intersection of Colonel By Drive and Main Street along with preparatory road, sewer and watermain work, including:
- Colonel By Drive at Main Street – Intersection improvements
- Full signalized intersection design including cycling connections to the canal pathway and proposed Main Street east and west cycling facilities to be constructed in the subsequent construction phase. The previously proposed multi-use pathway on the south side of Main Street is not compatible with current intersection design standards.
- Geometry changes to the intersection of Main Street and Colonel By Drive allow for a north-south crossing of Main Street
- Colonel By Drive – Hawthorne Avenue to north of Highway 417 – storm sewer installation with trench reinstatement only, which involves reinstatement of the area immediately impacted by the sewer installation.
- Main Street – Greenfield Avenue to Echo Drive – watermain, sanitary sewer, and storm sewer installation and temporary reinstatement of the area immediately impacted by the sewer, and watermain installation. Full road reinstatement will be conducted in the subsequent phase of construction
- Echo Drive – at Main Street - watermain, sanitary sewer, and storm sewer installation with temporary road reinstatement.
