Members of the Livermore-Pleasanton Fire Department and local police saluted along Interstate 580 overcrossings Friday morning and again that afternoon as the funeral procession for Sgt. Mark Dunakin, 40, of Tracy passed below.
He was one of four fallen Oakland police officers who were laid to rest after services at the Oracle Arena in Oakland.
The largest gathering of those honoring Sgt. Dunakin and his family was from the Las Colinas overpass just east of First Street in Livermore, seen in these photos.
After they faced two fire engines toward each other, extending their ladders to connect, firefighters hung a giant American flag and saluted as law enforcement agencies from cities such as Tracy, Manteca, Hanford and Merced headed west on 580 to the police funeral at Oracle Arena in Oakland for the four slain officers.
Later Friday afternoon, firefighters again saluted the procession, providing a "final" tribute from I-580 overpasses as the family headed home for a burial service.
