ACTT Workshop: Rhode Island
Pawtucket Bridge No. 550 - Building a Foundation for the Future
Chapter 4: Conclusions
4.1. Next Steps
Most of the participants had not been introduced to the limitations of the project prior to arriving in Providence and had only a short time to brainstorm and develop innovative solutions for the unique constraints of the Pawtucket Bridge No. 550 project. The Accelerated Construction Technology Transfer workshop provided an impartial examination of the project by experts from other areas of the country, each proffering their own ideas, expertise and insights for achieving the project goals. The solutions presented during the workshop reinforced some of the original design concepts and provided new direction for other aspects of the project.
RIDOT is evaluating the recommendations from all the skill sets and will determine which ideas or suggestions should be adopted for use. Some of the key ideas that ridot is investigating further include the following:
- Complete replacement of Pawtucket Bridge No. 550.
- Horizontal skidding as part of the superstructure replacement method.
- Permanent closure of the George Street/I-95 northbound on-ramp.
- Restructuring of local traffic patterns to eliminate the need for a C-D road alongside I-95 northbound.
- Reducing the construction timeframe by one-third to one-half.
Background of ACTT
ACTT is a process that brings together public- and private-sector experts from across the country in a setting that encourages flexibility and innovation. The goal is to recommend technologies that will accelerate construction time while reducing user delay and community disruption. This necessitates a thorough examination of all facets of a highway corridor with the objective of improving safety and cost effectiveness while minimizing adverse impacts to the traveling public.
The ACTT concept was originated by the Transportation Research Board (TRB) in conjunction with FHWA and the Technology Implementation Group (TIG) of the American Association of State Highway and Transportation Officials (AASHTO). Following the completion of two pilot workshops, one in Indiana and one in Pennsylvania, the originating task force, A5T60, passed the concept off to FHWA and TIG to continue the effort. They have done so by coordinating a series of ACTT workshops around the country, with several more pending in 2005 and 2006.
