Halifax Harbour Bridges (HHB) advises that the A. Murray MacKay Bridge will be closed to all traffic from Friday, August 22 at 8 p.m. until Monday, August 25 at 5:30 a.m. to complete critical maintenance work.
During this time, Angus L. Macdonald Bridge will remain open as usual, with normal weight restrictions in place. With the exception of passenger buses, vehicles weighing more than 3,200 kilograms are not permitted to cross Macdonald Bridge. Strict enforcement will be in effect throughout the closure.
As well, all Halifax Bound Hwy 111 Traffic will be pushed to Victoria Road. Both ramps on Princess Margaret Boulevard, connecting to and from HWY 111 and the MacKay Bridge, will be fully closed in both directions. No traffic will be allowed to enter or exit using these ramps during this closure.
Motorists should expect traffic delays and are encouraged to:
- Allow extra time to reach their destinations
