Fallujah is located about 50 kilometers (31 miles) west of Baghdad and sits on the eastern bank of the Euphrates River. Two bridges cross the river into the city. To the north is the King Faisal Bridge, a green steel trestle bridge in the western section of the city that was the flash point for impending battles. To the south is the bridge that carries Highway 10 over the river and through the center of the city. Coalition forces called the highway Phase Line Fran. More than 2,000 city blocks form a grid of main roads, side streets and alleyways. The train tracks that run across the northern boundary of the city were the breach site of the coalition force main effort at the beginning of the battle.
