Cobourg, ON – September 11, 2024 – Northumberland County is advising residents of the full closure of Brook Road North, Cobourg (CR 20) between Elgin Street East and King Street (local access only) from September 23 to October 11, 2024. This closure is necessary to allow a developer to install underground infrastructure for water and sewer, as well as to widen Brook Road North to accommodate the construction of a left turn lane, as part of the ongoing development in the area.

During this period, Brook Road North (CR 20) will be closed to local traffic only, with local access maintained just south of Elgin St. East.  All other traffic will be rerouted via D’Arcy St., with signage to direct traffic.  This closure will affect emergency services, bussing companies, and businesses in the area. However, this approach is expected to shorten the construction timeline by five weeks, with an anticipated re-opening by October 11.

Construction is currently ongoing on Brook Road North, with lane restrictions in effect.  Following the full road closure, which ends on October 11, periodic lane closures will continue during daytime hours, with full project completion expected by the end of October. 

In a special Northumberland County Council meeting on September 9, Council debated two options: maintain one lane of traffic, extending the construction period over several months, or implement a full road closure for a shorter three-week duration. Council voted to approve the full road closure starting on September 23 as requested by the developer.

“We understand this closure may cause some inconvenience, and we appreciate the patience of residents and businesses,” says Director of Public Works Denise Marshall. “We will work closely with the developer to ensure the infrastructure upgrades are completed safely and efficiently, while minimizing disruption as much as possible.”

Residents and businesses along Brook Road N (CR20) and those affected by the detour, are encouraged to plan their travel accordingly. Northumberland County will continue to provide updates as the project progresses.
