The city is imposing turn restrictions on Cathedral Lane during peak hours on weekdays.
This is in the hope of reducing extreme traffic congestion recently seen on the street, after nearby streets were closed last week because of the collapsed crane.
The closure of South Park Street between Spring Garden Road and Brenton Place has meant more cars are travelling down Cathedral Lane.
The city says the increased traffic has caused major slow-downs in the area, especially during morning and afternoon rush hours.
Beginning tomorrow, and continuing through every morning and afternoon peak period for the coming days, there will be no left turns permitted onto Cathedral Lane from Spring Garden Road or from University Avenue. Right turns onto Cathedral Lane from University Avenue will also be prohibited.
Peak periods are considered 7 a.m. to 9 a.m., and 4 p.m. to 6 p.m.
The municipality is also restricting parking and stopping at all times along the west side of Cathedral Lane from Spring Garden Road to University Avenue, and will be putting up signage in the area.
HRM staff also say the accessible parking space currently on Cathedral Lane will be moved to Spring Garden Road.
The city is encouraging drivers to use adjacent streets like Summer and Robie, and says these restrictions will be in place until further notice.
