It connects the town of Petty Harbour-Maddox Cove with Goulds and St. John's Route 11 begins as Petty Harbour Road in Goulds at an intersection with Route 10.

It heads east up a narrow valley through neighbourhoods to leave Goulds and cross over a lake and wind its way through some mountains.

Route 11 passes through some neighbourhoods before entering downtown Petty Harbour and turning north along Main Road.

[2] Route 11 heads straight through rural wooded areas for several kilometres as it gains some elevation before coming to an intersection with Blackhead Road, with Route 11 turning west on that road.

It then makes a steep descent as it negotiates some sharp switchbacks to cross under Route 2 (Pitts Memorial Drive).
