Simcoe County Road 90 is two lanes wide between McKinnon Road, north of Angus, and Ferndale Drive in Barrie, although a passing lane is provided for eastbound traffic between Angus and Essa. The road also widens to four lanes briefly at the junction with former Highway 131 west of Barrie, as well as within the city and within Angus. The land use surrounding the route is mixed, with pastures and forests composing the majority of the setting. Residences and small businesses are also scattered throughout the length of the route.
