There will be no single lane closure for the Centennial Bridge from March 20 to March 23, due to unforeseen events.
Further lane closures will be scheduled at a later date and communicated to the public in advance.
For the safety of workers on site, some operations related to closures can only be carried out during daylight hours.
DTI is further confirming future closure dates for the spring, including additional full nighttime closures.
Please continue to follow @brunswick511 for further updates.
The Centennial Bridge opened in 1967 and remains a vital transportation link carrying Route 11 traffic across the Miramichi River, accommodating approximately 8,000 vehicles per day.
With an overall height of 240 ft over a navigational channel, the 1.1 km Centennial Bridge is one of the largest structures in DTI’s inventory and allows for the passage of freighters, barges, and other commercial marine vessels.
A comprehensive assessment in 2009 concluded that the service life of the structure could be extended another 50-60 years with a full-scale rehabilitation project.
Work on the 14-year, $120 million rehabilitation project began in 2012, and encompasses repairs and upgrades to the steel superstructure, rehabilitation of foundation elements and replacement of the concrete deck. As part of the project, a new sidewalk will also be installed.
To date, some of the piers have been rehabilitated and steel painting is complete. Remaining work for 2022 includes the start relocation of utility infrastructure, bearing replacements and completion of the land piers. Occasional bridge closures are required to complete this work.
Future project phases will include work to widen the roadway across the bridge, additional pier improvements, deck replacement and steel rehabilitation.
Extended full closures are expected in 2023, 2024 and 2025. The Department of Transportation and Infrastructure is working closely with the City of Miramichi to mitigate the impact of any planned closures.

The timeline will be updated as the project phases progress through to the expected targeted completion date of late 2025.
During various project phases, the bridge will have overnight, single lane and full closures. A detour route will be in place during these times.
The department will continue to review the execution of the work to minimize disruptions with all closures or additional traffic changes and closures communicated to the public in advance.
