Holland Avenue Watermain Construction Project

City of Ottawa

Project Details

The initial scope of this project was to replace the aging and undersized watermain along a section of Holland Avenue, between Scott Street and Tyndall Street including trench reinstatement. Two spot repairs of an existing 600 mm diameter sanitary sewer north of Wellington Street were also required. The City added the widening of the sidewalks and a pavement overlay to the scope of the project and construction of a traffic signal interconnect under the widened sidewalk spanning the entire project length.

A number of larger residential and commercial buildings are located between Wellington Street and Scott Street. Coordination with these key private stakeholders during the design stage was required to ensure that minimum access requirements for vehicular traffic could be maintained.  Holland Avenue is busy major collector road with OC Transpo bus service and very high volumes of pedestrian traffic from the nearby Federal Government Campus at Tunney’s Pasture, commercial offices, and residential apartments. Therefore, the development of a comprehensive traffic management plan (both vehicular and pedestrian) was a critical component of this project. Roadway modifications along Holland Avenue between Byron Avenue and Tyndall Street were also included to help improve the safety of cyclists navigating the Byron-Holland-Tyndall intersections.
