Abstract:
As part of a national initiative sponsored by the Federal Highway Administration under the Highways for LIFE program, the New York State Department of Transportation (NYSDOT) was awarded a $1.407 million grant to replace two bridges on I-190 over Buffalo Avenue in Niagara Falls, NY, to demonstrate the use of proven, innovative technologies. This report documents Accelerated Bridge Construction (ABC) techniques using modular deck beam technology. Under conventional construction methods, it would have taken three months to replace each bridge, impacting traffic on I-190, Buffalo Avenue, and the portion of Robert Moses State Parkway that connects Niagara Falls State Park to I190. However, using precast modular deck beam technology, impact to travelers on I-190 was limited to only 72 hours for each bridge replacement. Travelers on the Parkway and Buffalo Avenue were impacted for five weeks, during which time Buffalo Avenue was reconstructed and lowered to correct an under-clearance deficiency. It was projected that by compressing the construction time using ABC, two crashes were avoided at the site. Innovative iCone® technology was used to gather speed data and interpret queuing and incidents in the work zone. The construction cost for the innovative bridge replacement was an estimated $0.276 million less than that for the conventional method, and user delay cost was also reduced by an estimated $2.279 million. When bundled together, there was an estimated total savings of $2.555 million. This represents about 33 percent of the $7.743 million successful bid on the project. A post-construction user satisfaction survey indicated that, overall, more than 88 percent of the respondents were satisfied or very satisfied with the ABC techniques used to expedite construction. Because of the success of this project, NYSDOT plans to accelerate bridge construction using modular deck beam technology on future projects where it is feasible and appropriate for conditions
