The goal of rehabilitation of bridges with minimum impact on traffic flow, with improved safety and quality performance are going to be the drivers of bridge construction plans in future. Innovative methods and contracting techniques are important techniques which can be effectively used to achieve these goals. However, effective use of these tools requires substantial deviation from traditional methods, systems currently used by DOTs. Ohio DOT created Strategic Initiative #9 (SI 9) “Building Bridges Faster, Better, and Smarter” to address this issue. This paper describes the innovative construction procedures used in the rehabilitation of two laterally post-tensioned box girder bridges and provides recommendations for better project deliverables based on the observations made during the construction. Partnering between agencies and contractor can increase the chances of project success substantially. The capability of local contractors needs to be kept in mind while specifying the use of new, innovative materials and construction techniques. This is especially true for smaller projects where contractors have limited capabilities. The agencies need to re-evaluate their standard operating procedures to reflect the new philosophy of accelerated project delivery.
