Safety is a top priority and Parks Canada's investments will improve visitor experiences at our national parks and national historic sites on Cape Breton. 

How long will I wait in construction?
Wait times may vary at each construction site. To minimize wait times:

  • Traffic lights and traffic control personnel will be used.
  • Where possible, two lane detours will be used at bridge work.

There may be periodic two-lane closures for no longer than 20 minutes.

Why is Parks Canada doing this construction during peak tourism season?
The majority of roadwork involves large bridge and highway projects. These types of projects require summer weather to ensure materials can be installed properly. Bridge projects must also be completed when water levels are low to prevent negative impacts to aquatic environment.
