Prince of Wales Drive (Ottawa Road #73) is a road serving Ottawa, Ontario, named after the eponymous road in Battersea, London, U.K. The northern section is a low-speed street running along the west bank of the Rideau River, while southern portions of the road were formerly Highway 16 (downgraded after the construction of Highway 416).
Prince of Wales Drive is the continuation of Queen Elizabeth Drive beyond Preston Street. It runs around Dow's Lake and through the Central Experimental Farm before reaching a roundabout. The speed limit is 50 km/h (31 mph) down to Fisher Avenue, at which point it increases to 60 km/h (37 mph). There is a major intersection with Hunt Club Road, where several commuters from south Nepean use the bridge to cross the Rideau River.
Prince of Wales Drive follows the Rideau River past Barrhaven and Manotick. South of the intersection with Jockvale Road, the road diverts from the river and heads in a southwesterly direction toward North Gower, where it terminates at 4th Line Road.
Prior to the construction of Highway 416, the stretch of Highway 16 that included Prince of Wales continued south to the Canada–US border into Saint Lawrence County, New York
