The Maslenica bridge, photographed here in 1990 fulfilled that task. It was destroyed in 1991 and rebuilt from 1993 to 1997. You will find a picture of the new bridge on Maslenica (link given by Diocletianus, thanks, Niksa)
When you arrive from the north, 30 km before Zadar, you have to get across the strait that links the Velebitski Kanali to the Novigrad More. The strait is narrow but the hills are high on both sides. Thus only a very aerial bridge can get across.
