| Reconstruction of existing viaduct: This alternative was developed to represent the least-cost (and "no-build") alternative. It included the rehabilitation of the existing six-lane viaduct, but did not provide for any operational improvements.
North Alignment: This alternative called for the construction of an eight-lane elevated freeway constructed parallel to the existing facility. While it was to provide some operational improvements, it was to maintain the substandard interchange between I-95 and I-195.
Hurricane Barrier Alignment: This alternative called for the construction of a new eight-lane freeway along a southerly ("Hurricane Barrier") alignment, a new bridge over the Providence River, and a new interchange between I-95 and I-195 south of the existing interchange.
In 1993, the RIDOT and the Federal Highway Administration (FHWA) selected the Hurricane Barrier Alignment as the preferred alternative. The two agencies issued the following statement on their "Record of Decision," from which excerpts are given below:
The reasons for selecting the Hurricane Barrier Alignment include the following: it improves highway safety, reduces impacts on historic districts, allows for the fullest implementation of the city's Old Harbor Plan, has a net positive impact on India Point Park, provides improved access to Rhode Island Hospital, and incurs to least impact to traffic during construction.
