The new Ganga River Bridge near Patna in Bihar, India is 4km long and features four lanes plus two sidewalks.

McElhanney’s bridge design and erection engineering group (formerly Infinity Engineering) is responsible for the detailed design and construction of the 1920m long navigation spans portion of the alignment under a fast-tracked schedule. Infinity value engineered an alternative segmental concrete extradosed superstructure concept with back-to-back 120m long navigation spans that reduced the construction duration of the bridge. The 25m wide superstructure consists of a single cell precast segmental box modified to accept extradosed cable construction through balanced cantilevering.
