Commencement of Sir John A. Macdonald Parkway Cut and Cover Tunnel Preparatory Works

May 13, 2019

As part of the future cut and cover tunnel of the Stage 2 Confederation Line West extension, crews are beginning preparatory activities on the Sir John A. Macdonald Parkway between Dominion Avenue and Cleary Avenue.

This preparatory work is scheduled to begin the week of May 13 and continue into 2020, which will allow cut and cover construction to safely occur on the south side of the Sir John A. Macdonald Parkway without interfering with traffic. All work is being done in accordance with the regulatory requirements for the project, and with planning participation and approval from the NCC.

KEY ACTIVITIES AND TIMELINE

Phase 1: Beginning week of May 13 through June 7

 Site mobilization and area clearing along the centre boulevard (median) to the north of Sir John A. Macdonald Parkway. This work includes:

  • Installation of low silt fencing between the Ottawa River and the future work site to protect habitat and prevent turtles from entering the construction zone;
  • Removal of vegetation and trees located within the median and north of the Sir John A. Macdonald Parkway with biologist and arborist oversight;
  • Mobilization of crew and equipment onsite, including pick-up trucks, a bucket truck and loader, along with a log truck for removal; and
  • Tree replacement as part of final restoration will be in accordance with the tree compensation plan for the project.

This work is scheduled to occur during typical daytime construction hours between 7 am and 10 pm Monday to Saturday, and between 9 am to 10 pm on Sunday’s and holidays.

From May 21 to June 7, 2019, sections of the eastbound and westbound lanes of the Sir John A. Macdonald Parkway, between Woodroffe Avenue and Dominion Station, will be closed, during off-peak hours, from 9:30 am to 3 pm.

Area clearing is in preparation for construction of temporary traffic lanes as part of Phase 2.

Phase 2: June through September*

Temporary traffic lane construction and utility relocation will occur to the north of Sir John A. Macdonald Parkway. Once completed, traffic will be shifted to the north side of Sir John A. Macdonald Parkway in preparation for work in the median.

Phase 3: September through December (and into 2020)*

Temporary traffic lane construction and utility relocation will occur in the median of Sir John A. Macdonald Parkway. Once completed, all traffic will be shifted to the north side of Sir John A. Macdonald Parkway that will allow cut and cover construction to safely occur on the south side without interfering with traffic.

Phase 4: September through December (and into 2020)*

Area clearing and tree removal will occur along the south side of Sir John A. Macdonald Parkway in preparation for cut and cover construction. Once again, all phases of work will be compliant with regulatory requirements and with approval with the NCC.

The underground light rail transit (LRT) system in this area will require in-trench construction to the south of Sir John A. Macdonald Parkway. The above-ground area will be cleared so that crews can begin the underground work where the future train will operate.

*Please note paving and other roadworks are weather dependent and dates will be subject to change.

HOURS OF WORK

The project team anticipates most activity to be scheduled during typical daytime construction hours. If nightwork is required to assist the travelling public, appropriate notice will be provided.

ANTICIPATED IMPACTS

Pedestrians and Cyclists

Pedestrian and cycling access along Sir John A. Macdonald Parkway will be maintained. Temporary crossings will be implemented along the construction corridor and pedestrians and cyclists should use extra caution as traffic patterns change.

Motorists

Traffic will be maintained although delays may occur at times. Intermittent daytime off-peak lane closures will be required at times. Motorists should be aware of and adhere to traffic control signage, posted speed limits and traffic control personnel.

Residents and Businesses

Noise and temporary disruption are not anticipated to be significant during this work. Access to and from properties will be maintained although local traffic delays may occur at times. 

The safety of workers and the public is paramount, and we thank you for your patience during construction.

WHAT’S NEXT

In early 2020, crews will complete any remedial work in Phase 4 and begin cut and cover activity in this area. More information will be available once confirmed later this year. Please stay connected with our team as we report on our progress and provide our 2020 construction look-ahead.
