2.0 Replication Capability
•
Part of this project – the Providence River Bridge design – is an example of the new use of existing technology in the U.S. The design techniques and the offsite constructability can certainly be replicated elsewhere, especially on projects where there is a need for cost or time savings that could be enhanced by use of a design that allowed for lighter weight materials and that allowed for a move of the structure, which then allows for concurrent construction of structure and foundation.
•
Additionally, if concurrent construction is considered, the use of lighter materials allowed for the network arch span to be moved (in this case over water by barge). This project incorporated the use of Self-Propelled Modular Transporters (SPMTs), which the Federal Highway Administration recommends use of in its Manual on “Use of Self-Propelled Modular Transporters to Remove and Replace Bridges.”

Maguire Group / Iway Project
3.0 Cost and Efficiency Considerations •
The project had many cost-saving / efficiency aspects including: – Design: allowed use of less heavy and less costly materials – Lightweight structure allowed bridge move – Concurrent Construction: building offsite allowed concurrent foundation construction / span construction
•
Budget and cost, although as important on this as on any other large-scale project, were not the only driving factors for success.
•
Completing the project on time and with the least inconvenience to Rhode Island’s drivers was an overriding component that drove design and building considerations.
•
RIDOT as well as FHWA were engaged throughout the solution process. All are pleased that the project is on track to meet the current budget of $610 million.

First major use of selfpropelled modular transporters (SPMTs) in Rhode Island The FHWA features the use of SPMTs on the Iway project in its Manual on “Use of SelfPropelled Modular Transporters to Remove and Replace Bridges”
Maguire Group / Iway Project
4.0 Technical Value to Industry Iway Bridge Loaded onto SPMTs
Lighter weight of network arch allows for concurrent bridge / foundation construction and eventual moving of structure onto its foundation. For this project, bridge movers Mammoet used devices that are relatively new to U.S. construction: self-propelled modular transporters (SPMTs). In the past, other bridges have been built on barges and transferred to construction sites, but the rental cost of the barges can be high. The SPMTs allowed a short-term rental of the barges, saving the contractor significant money.
