For purposes of this restriction, the province is divided, west to east, by:

• A line formed by the Severn River to Regional Rd. 169

Single trip permits, for moving of overloads on highways not designated in Schedules 1, 2 and 3, may be issued, but are subject to axle controls established by the Ministry of Transportation.

Pursuant to the Highway Traffic Act, the ministry will impose reduced load limits for those designated parts of the King's Highways listed in Schedule 2, when appropriate, between March 1, 2025 to May 31, 2025.
