The City of Oshawa has notified that Darcy Street, between Juniper Street and Oshawa Boulevard North, will be closed until December 31.
“While every effort is being made to complete this project with minimal impact to the area residents we have received numerous inquiries and concerns related to this work. We take these concerns seriously, which is why we are updating the residents in the area on the current project status and work remaining,” said a city statement.
Through a competitive bidding process earlier this year, Oshawa retained Trisan Construction to complete the replacement of the Darcy Street municipal structure between Oshawa Boulevard North and Juniper Street.
To date, Trisan has closed access to the work area, removed the existing roadway and pedestrian connections, and supported/relocated some existing utility ducts. In order to remove the existing structure and replace it with the new structure, the creek has been diverted using a series of three pumps and piping.
This work was advanced in coordination with the Central Lake Ontario Conservation Authority (Cloca). A single pump is required to run at all times while the creek is diverted to maintain the creeks flow. The additional pumps are in place to mitigate high flow levels during storm events and will only be used if required.
Trisan was on site recently to address an unplanned regional sanitary sewer issue that occurred. An additional sanitary pump will be required for a short period of time to bypass the existing sewer line while emergency repairs are made by the contractor on behalf of the Region of Durham. Scheduled project work will proceed following the sanitary repairs.
Some upcoming project milestone:
- Existing regional watermain will be lowered and protected though the work zone to accommodate the placement of the new structure.
- New structure sections will be placed, from north to south.
- All bypass pumps will be removed following the installation of the new culvert sections and creek diversion will be removed. Anticipated completion date is mid to late December 2022.
- Backfilling and road reconstruction (paving, sidewalks, landscaping, etc) activities will follow the new culvert installation.
The overall project is anticipated to be complete in January 2023.
Please note that although the contractor is making every effort to complete this project in a timely and safe manner, the work is contingent on acceptable weather conditions.
The city had earlier announced the closure from June 2.
