This study was conducted in response to the increasing number of rural bridge replacements within historic contexts encountered by state DOTs. The research objective of the project was to develop a practitioner-ready resource of context-sensitive design examples appropriate for workhorse bridges in rural historic districts. A synthesis of these examples provides practitioners with the tools to navigate the complex process of designing a context-sensitive bridge for the replacement of a workhorse bridges in rural historic districts. A secondary objective was to address design components common to successful context-sensitive designs as well as the costs associated with such designs. The project team developed the following Practitioner’s Guide and technical Research Report, and a supplemental Design Idea Book. The Practitioner’s Guide (Part I) is organized to walk practitioners through the complex process of designing a context-sensitive bridge for the replacement of workhorse bridges in rural historic districts. The Research Report (Part II) presents a summary of the literature review and state of practice survey of the current context-sensitive design (CSD) process for replacement of workhorse bridges in rural historic districts. The intent of the Design Idea Book, a separate illustrated document, is to present design features that have been used to achieve context-sensitive designs in or adjacent to rural historic districts. The highly illustrated Design Idea Book is laid out for use during the design and public involvement process to provide a range of possible bridge designs and approaches to the context-sensitive design/solutions (CSD/S) of workhorse bridge replacements.
