Ostružnica is located on the right bank of the Sava river, at the mouth of the Ostružnička reka, 14 km southwest of Belgrade, south of the Ada Ciganlija island.

As the opposing, Syrmian side across the Sava was a vast marsh at the time (modern New Belgrade), the bridge didn't stop at the bank but continued for some length above the swamp.

According to the records, a seasoned Belgrade master craftsman Đorđević "in only one month, with the help of his 400 workers, built the Long Bridge, using 2,000 tree trunks, 1,100 wooden piles, 15,500 bundles of palings and 12,000 palisade pickets."

[3] Doljani is a former settlement that was located in the upper part of the Doljanski potok stream, between villages of Velika Moštanica, Meljak and Sremčica, just south of today's Ostružnica.

A new Ostružnica road bridge, in the final stages of construction, was bombed during NATO air attacks on Yugoslavia in 1999 and wasn't finished until 2005.
