Hazeldean Road bridges – approach slab renewal

Project Status: 
Underway

Project overview

The City of Ottawa is renewing the approach slabs, leading up to the Hazeldean bridges, located on Hazeldean Road over the Carp River, on the east and west ends. An approach slab is the transition between the asphalt roadway pavement and the bridge structure. This $1 million investment is required to address the approach slab and is part of the long-term plan to maintain the bridge structures.

What: The project will include removing the existing settled sidewalk and asphalt roadway at the approaches. A reinforced concrete support beam and slab will be installed. The sidewalks and asphalt will then be reinstated.

Why: The Hazeldean bridges were constructed in 2012. Regular inspections have shown the structures to be in good condition, however, the approach slabs (the transition between the roadway pavement and the bridge structure) have settled over time, causing localized cracking and vibrations. This investment is part of the City’s commitment to maintain its infrastructure assets.

When: Construction is expected to start in mid-April 2021 and is planned to be completed in July 2021.

Where: The east and west approaches to the Hazeldean bridges, approximately 500 metres southwest of Terry Fox Drive.

Who: The contractor, Thomas Cavanagh Construction Limited, will perform the construction work for the City of Ottawa.

Communications

The City has a proactive communications approach. The project team will update residents and stakeholders on the project using different methods to communicate, including signage and posting information on ottawa.ca.

Traffic impacts

This project has been strategically planned to minimize the impact to commuters, businesses and residents. Portable Variable Message Signs (PVMS) will be displayed to notify traffic in advance of, and throughout, construction. Respective signage will be in place for pedestrians, cyclists and vehicles.

Construction will be completed in two stages: Stage 1 will close the south bridge, and Stage 2 will close the north bridge.

Pedestrians

  • Pedestrian access across the open bridge will be maintained throughout construction. Pedestrians will be advised with signage to use the opposite sidewalk when either bridge is closed for construction.

Cyclists

  • Cyclists will be detoured with signage to the pathway below the bridge (see Figure 1 and 2)
  • Figure 1
  • Figure 2

Vehicles

  • Lane closures will be in place throughout construction, with one lane open in each direction.
  • Access to the football field and local businesses will be maintained throughout construction.

Construction disruptions

The contractor will take every precaution to minimize interruptions to the everyday life of your family and/or operation of your business, but, as you can appreciate, there may be some inconveniences during the course of the work, such as traffic delays and noise. We would like to thank you for your patience and cooperation.

For construction activity hours of work, the City of Ottawa follows provincial requirements and the City’s Noise By-law (2017-255).

Frequently Asked Questions

  1. How was this project determined? Regular inspections of all City bridges are conducted based on Provincial guidelines. The most recent inspection identified the need to renew the approach slabs which have settled over time.
  2. The bridge was constructed in 2012, why is this work required? In addition to the regularly scheduled bridge inspections, a geotechnical investigation identified the probable cause of the settling, which is related to the difference in material support between the bridge (bedrock) and the approaches (engineered fill) as determined through the analysis of soil samples of the fill material. By renewing the approach slabs, the project is mitigating further settlement and is part of the City’s commitment to maintain infrastructure assets.
  3. What is a bridge “approach slab”? An approach slab is the transition between the roadway pavement and the bridge structure. In the case of the Hazeldean bridges, the approach slabs are shown in the image below, in red.
    The four approach slabs on the Hazeldean bridges.
  4. Will the Carp River below the bridges be impacted? No. Impacts to the Carp River are not anticipated.
  5. What is the project budget? The approved budget is approximately $1 million.
