Sherman Access and the Sherman Cut will be blocked in both directions for four days starting Tuesday.

City officials say the closure, which will shut down both the east and west legs starting at 9 a.m., is part of ongoing road maintenance for Sherman Access.

The city expects all sections of the road will remain closed until Friday at 7 p.m.

Drivers are warned to find an alternative route to avoid the closure.

"Hamilton thanks motorists for their patience and co-operation as we work to ensure continued public safety along the escarpment roadways," reads a media release from the city.
