The first day of construction, as the city prepares to build the first of two roundabouts, caused traffic headaches for commuters and it doesn't seem as though it's going to get better any time soon. 

Callers to CBC's Mainstreet reported much heavier than usual traffic on Gottingen and Maynard streets as rush hour commuters tried to find a way around North Park Street, one of the main arteries to and from downtown. 

Halifax’s North Park Street is closed for five weeks as a major intersection gets turned into a roundabout.

North Park Street, near the Armoury, is blocked at both ends as they build the northern roundabout to Agricola Street.

Jennifer Stairs, spokesperson for the Halifax Regional Municipality, said in a news release Thursday that the traffic signals at the intersection of North Park, Cunard, and Agricola streets are temporarily not working.

Motorists are advised to avoid the area if they can early Thursday. Stairs said the lights should be back on later in the day.

Stairs said pedestrians and cyclists should travel on the Halifax Common trail, as the east sidewalk of North Park will also be closed.

After the first five-week phase, North Park Street will be closed in sections, along with some side streets. Crews will work Mondays to Saturdays until the end of October.

A second roundabout, at North Park and Cogswell Street, will be built next summer.
