A 29-year-old man and a boy, 17, were in a silver VW Polo when it was involved in the incident on Northam Bridge early on Saturday, Hampshire Constabulary said.
The pair have been arrested on suspicion of causing death by careless or inconsiderate driving and are in custody, the force said.

The teenage motorcyclist from Fareham, Hampshire, was on a white Yamaha YZF.
He died in hospital from his injuries.
Hampshire Constabulary has appealed for any witnesses to the collision to come forward.
