She began working with her new husband, sculptor
Claes Oldenburg, in 1976. Her first work with Oldenburg came when she helped him install his 41-foot
Trowel I on the grounds of the
Kröller-Müller Museum in Otterlo. Together Oldenburg and van Bruggen produced three decades of monumental sculpture that van Bruggen would call Large-Scale Projects, with their first piece created as a team being
Flashlight (1981), a huge outdoor sculpture at the
University of Nevada, Las Vegas. In 1988, her work with Oldenburg entitled
Spoonbridge and Cherry was commissioned by the
Walker Art Center. It became a permanent fixture of the
Minneapolis Sculpture Garden as well as an iconic image of the city of
Minneapolis. Their final joint work, fabricated in Turin, Italy and titled
Tumbling Tacks (2009), was designed for the
Kistefos Sculpture Park in the countryside north of Oslo. In 2021, Pace Gallery presented an exhibition of van Bruggen's collaborative work with Claes Oldenburg spanning the 1980s to the late 2000s. Claes Oldenburg's Bottle O' Notes.jpg|''Bottle O'Notes'' (Middlesbrough) FlyingPins.jpg|
