Synthesis of Information Related to Highway Practices. Topic 55-08. Construction Strategies and Techniques for Planned Bridge Replacements in Complex Scenarios

A significant number of bridges on the national inventory are being replaced yearly by state departments of transportation (DOTs). Many of those replacement bridges are on critical arteries necessitating complex and, in some cases, costly strategies and construction techniques. The resulting techniques for replacing the bridge need to balance the goals of maintaining mobility, work zone safety, construction quality and environmental impacts, along with budgetary and schedule constraints. Typical bridge replacement construction strategies and techniques for complex scenarios may include: Staged construction; Construction of the new bridge off the existing alignment and shifting traffic; Accelerated Bridge Construction techniques minimizing disruption; Temporary bridges (diversions or runarounds); Closure and full detour; and, Other strategies state DOTs use. State DOTs will consider a variety of factors when deciding how to approach the bridge replacement project, such as: Existing and proposed bridge geometrics/properties, structure type; Average Annual Daily Traffic (e.g. percent truck traffic, pedestrian impact); Detour out-of-distance travel; Site characteristics (e.g. hydraulic, geotechnical, geometric requirements, archaeology); Environmental impacts (e.g. environmental justice, wildlife habitat, endangered species, water and soil contamination); Right-of-way procurement, temporary and permanent; Material type, availability, and quality; Construction season (weather), duration of project; Construction techniques and quality; Demolition constraints; Roadway safety; Asset life-cycle cost; Stakeholder input; Direct cost; Indirect cost; Funding constraints; Asset life-cycle cost; Contract period strategy (e.g. working days, calendar days, incentive/disincentive, A+B); and Project delivery method (e.g. design-bid-build, design-build, CMGC, P3). The objective of this synthesis is to document practices and decision-making used by state DOTs for planned bridge replacements in complex scenarios. Information to be gathered includes (but is not limited to): Construction strategies and techniques state DOTs use to construct bridge replacements; Factors and constraints state DOTs consider when choosing the appropriate bridge replacement construction strategies and techniques; and Written policies, rubrics, guidelines, metrics, and tools state DOTs use for bridge replacement decision-making in complex scenarios.
