A second milestone has also been achieved recently, with the Indiana approach now connected to the bridge deck at the nearest tower.

The new bridge is being built with nine piers, four on land and five in the water. Three of the piers include tower supports, the tallest of which is at the centre and reaches 85m. The matching towers on the Kentucky and Indiana sides stand 70m tall.

Contractor for the scheme is Walsh Construction.

Downtown Crossing, which forms part of the Ohio River Bridges project, is expected to be open to two-way traffic by January. The Ohio River Bridges project also includes another major cable-stayed bridge, the US$1.058 billion East End Crossing.
