The Saint John Harbour Bridge will be closed intermittently starting Thursday and continuing until early November.

The New Brunswick Department of Transportation and Infrastructure (DTI) says the intermittent closures will last about 20 minutes and all lanes of traffic will be closed during those times.

The closures will happen outside of the following peak traffic hours:

• 7 a.m. to 9 a.m.
• 11:30 a.m. to 1:30 p.m.
• 4 p.m. to 6 p.m.

DTI says motorists should expect delays but didn’t specify when the closures will happen outside of peak traffic hours.

The bridge has been undergoing a phased refurbishing project since 2021. The project could cost as much as $31 million by the time it’s finished in 2027 – up from the project’s initial budget of more than $26 million.

The federal and New Brunswick governments announced $15 million in funding for the project in February 2023.

The project, which will include new work on the bridge’s two east end ramps, entered its final stage last year.

The provincial government says the construction project will extend the 1.3-kilometre structure’s lifespan by 30 to 50 years.

The Saint John Harbour Bridge first opened to traffic in August 1968.
