The medical examiner says the dead man is 40-year-old Chad Vida, of Etna, a nearby suburb.
Pittsburgh police have yet to name the driver, though they say they know that person's identity.
Police say Vida was found lying on Liberty Avenue near the Bloomfield Bridge shortly after he was hit about 11:30 a.m. Saturday.
Police say the driver stopped to call 911 from a location near the accident scene and has been interviewed by detectives.
It was not immediately clear Monday if or when police planned to charge the driver. Police say they still need more information from any witnesses to complete their investigation.
