Route 3, also known as Goulds Bypass Road and Robert E. Howlett Memorial Drive, is a 9.4-kilometre (5.8 mi), two-lane, Partially-controlled access highway in the eastern part of the Avalon Peninsula of Newfoundland in the Canadian province of Newfoundland and Labrador.

The route is entirely in Division 1 and generally forms a straight line between its termini.

Route 3 begins at an intersection with Route 10 (Southern Shore Highway/Irish Loop Drive) in southern Goulds and heads northwest through wooded areas to cross a river via Raymond's Bridge and have an intersection with a gravel road before turning due north.

The highway now has an intersection with Ruby Line before entering the St. John's city limits and coming to an end shortly thereafter at an interchange with Route 2 (Pitts Memorial Drive), with the road continuing north as Commonwealth Avenue into downtown Mount Pearl.

For the majority of its length, Route 3 has a small gravel frontage road running along its southbound side.
