The Astaldi Group has won a $59m contract from Florida Department of Transportation (FDOT) in the US to upgrade the NW 25th Street in Miami-Dade county.

The contract involves rebuilding and enlarging the NW 25th Street, which is in Doral near the Miami International Airport, to four to six lanes and building a metal structure overpass in correspondence with the SR-826 Palmetto Expressway.

The contract also involves the construction of a 1.9km viaduct.

The works are expected to commence in early 2012 and will be completed in about three years.
