The Italian Strabag subsidiary Adanti has signed an agreement to upgrade around 11km of a state road between Grosseto and Siena in Tuscany.
The contract includes the planning and building of three junctions, six tunnels — the longest measuring 1.5km in length — and five viaducts, the most important of which measures 900m in length with piers up to 95m tall.
Adanti’s share of the €161M (£141M) contract amounts to around 65% or £92.7M.
Bologna-based Adanti S.p.A. will carry out the works together with consortium partner Vittadello Intercantieri di Padova. Construction is slated to begin in the spring of 2012 and is scheduled to last about two and a half years.
