Bridge replacement programme for Pennsylvania

A major programme of bridge replacement works on Pennsylvania will see the state replacing 558 highway bridges over a period of three years. The work is expected to cost in the region of US$899 million to carry out and was awarded by the 2535 Pennsylvania Department of Transportation (PennDot) to a group of firms called Plenary Walsh Keystone Partners. The package of works includes construction of the bridges over three years as well as a 25 year maintenance deal. The Plenary Walsh Keystone Partners comprises 1007 Granite Construction, Walsh Group and 2418 HDR Engineering. Construction will commence in the summer of 2015 followed by completion within three years. Inclusive of financing costs, an average of $65million/year will be paid by the state under the contract's 28-year term for $1.82 billion in total.
