One of the peninsula's main arterial routes is expected to be shut down for 4.5 months starting April 1.
A section of Quinpool Rd. will be closed off to vehicles, cyclists and pedestrians for repairs to the CN bridge.
Vehicles will be detoured to Chebucto Road and Connaught Avenue. Pedestrians and cyclists will be able to take Armview Avenue to Tupper Grove and Prince Arthur Street.
Local traffic will be allowed between the Armdale Rotary and Connaught Avenue, but with the bridge out of commission, no one will be able to cross over the tracks.
Halifax West Armdale Councillor Shawn Cleary says, because 27,000 vehicles use Quinpool Rd. every day, there's no doubt congestion will be an issue.
He tells NEWS 95.7 the best way to avoid major traffic headaches is to reduce the number of cars on the road during the morning and afternoon commutes.
"If people actually just changed the time they left to 10 to 20 minutes earlier or 10 to 20 minutes later, they would have a significant effect on congestion," he explains.
"The problem is people need to get going where they need to go in that 8:30 a.m. time period ... but, if more people took the bus, if more people walked and cycled, if more people carpooled, if employers gave their employees a little bit of flexibility, this may not be the carmageddon that we think it might be."
He's also hoping the months-long timeline is a worst-case scenario.
"We've seen them do the Oakland St. bridge last year and it's a smaller bridge, but it took them longer," Cleary says. "Now they did learn a lot of lessons doing it and they've assured us they can stick to this timeline."
The councillor explains the work involves tearing down the top layers of the bridge to reinforce the arch before building it back up.
As it is a CN project, he says Halifax Regional Municipality's only involvement is repaving the street when the repairs are finished.
"Because it's their project, we have very little authority to do anything to them ... I certainly will be helping residents connect with CN if there are issues so they understand the impact that it's having," he says.
"It's one of those things where I wish they had fixed it a lot earlier. It's to the point now where safety is an issue and CN has to fix the bridge, but it will cause some significant headaches."
