Crews from Walsh Construction have carried out the second major truss lift for the Milton Madison Bridge project on the Ohio River in the USA.
The 222m-long span was floated out yesterday and the 2,000t assembly was lifted some 25m onto temporary supports.

The bridge is being constructed using an innovative erection scheme by Buckland & Taylor that will culminate in sliding the entire 741m-long main bridge laterally onto the permanent piers.
For the Span 3 lift, the main navigation channel of the Ohio River was closed at midnight Sunday and reopened less than 24 hours later, explained Buckland & Taylor executive engineer Murray Johnson. The massive span was lifted using eight 300t strand jacks supplied and operated by VSL International.
