Construction Notice: East Extension
Excavation Works along Highway 174 at Champlain Street
April 2020
This notice is to advise that, as part of the Stage 2 O-Train Light Rail Transit (LRT) project, crews and equipment will be working along Highway 174 at Champlain Street to complete drainage, utility work and roadworks. Moderate to high noise levels are anticipated.
WHAT: Significant rock excavation, placement of drainage pipelines, and manhole installation will take place. Temporary concrete barriers will be installed along this section of Highway 174 prior to the beginning of work, to create a safe work zone. The Highway 174 westbound on-ramp, at Champlain Street, will be realigned in order to move the traffic further away from the work zone.
WHY: Crews will be excavating rock at a depth of several metres along the highway to accommodate pipe and manhole installation. This preparatory work is required prior to beginning construction on the future Place d’Orleans LRT Station. Crews will be working during day and overnight, in order to maintain the project schedule.
WHERE: Along Highway 174, east and west of Champlain Street.
WHEN: Late April 2020 through July 2020, Monday to Friday, and occasionally on weekends.
HOURS: Daytime and overnight work is required between late April and July 2020; a City of Ottawa Noise By-law Exemption Permit is in effect.
ANTICIPATED IMPACTS
All pedestrian, cycling and vehicular access will be maintained. Temporary concrete barriers will be in place to create a safe work zone, away from road users. Pedestrians and cyclists should use extra caution. Motorists may wish to allow for a little extra travel time, and should adhere to traffic control signage, posted speed limits and instructions of traffic control personnel.
Overnight work will occur Monday to Friday and occasionally on weekends under a Noise By-Law Exemption Permit. Noise levels are expected to be lower than 85dba. Noise levels will be monitored, and in an effort to mitigate, additional plywood sheets will be installed on top of jersey barriers to provide temporary sound attenuation.
The safety of workers and the public is paramount, and we thank you for your patience during construction.
