An aging National infrastructure, coupled with a tremendous increase in transportation demand, has caused the number of highway construction activities to magnify in recent years. In January 2005, the Rhode Island Department of Transportation (RIDOT) applied the ACTT concept to one of its projects by hosting a two-day workshop featuring nearly 60 experts from around the country. For its ACTT workshop, RIDOT selected a bridge project located on Interstate 95 (I-95) in the city of Pawtucket, just north of the State capital, Providence. The 695-foot-long bridge carries I-95 over the Seekonk River, Pleasant Street and Taft Street. Three corners of the bridge flare out to accommodate on- and off-ramps for the School Street interchange. With its unusual geometric layout and high traffic counts, the interchange is noted for frequent traffic congestion, and RIDOT must determine whether to replace or rehabilitate the existing, aging structure. |
