The longest span cable stayed bridge in Iran, the Lali Bridge carries an old road across the new reservoir formed by the massive new Gatwand Olya Dam. The structure consists of a central span of 256 meters and two side spans of 102 meters for a total length of 460 meters with no approach spans. The two lane deck is 13.5 meters wide. The deck was briefly 150 meters above the Karun River in early 2011 before the lake began to fill up behind the dam. The river surface went from an elevation of 104 meters to 230 meters at full reservoir.

The new span is situated 3 kilometers upstream from the original Lali Bridge, a British Bailey-style truss from 1950 that is now submerged deep under the new reservoir.

The cable stayed bridge is Iran's second highest after the West span of the Karun 3 Dam Bridges though all 3 crossings are over deep reservoirs created by the construction of downstream dams.
