This review of state DOT Complete Streets policies and survey of state DOTs point to an appreciation for and a commitment to maintaining active transportation features that are constructed as part of state highway networks and their connections to local roadway and trail networks. While several states have Complete Streets policies that include maintenance, few have evidence of much implementation, performance tracking, or changed practices. However, the work being done by those states addressing the issue of active transportation facility maintenance will provide new guidance, cost estimates, and more that can benefit all state DOTs.
Dozens of state DOTs have individually developed, implemented, and matured their own Complete Streets principles and programs based on best practices and local initiatives. States have refined their Complete Streets practices through other related initiatives, including context- sensitive solutions, practical design, community connections, sustainable transportation planning principles, and multimodal network development.
Published literature and survey data suggest that for many states, organizations and protocols have not been supportive of Complete Streets and that reorganization of the state DOT made a significant difference in implementation. In California, for example, the districts and headquarters needed to form new workflows and coordination tools. There are numerous functions at each DOT, each typically managed by its own team of specialists. The resulting silos and insular teams have been an impediment to implementation. It has been typical, and remains so in many states, for the bike and pedestrian functions to be performed by a single person or a small team, separate from the teams that develop projects.
Another typical organizational divide can be seen in how transportation planners within DOTs lead the bike and pedestrian or multimodal plans, while only design engineers contribute to the development of project plans and specifications. In Puerto Ricoʼs Highway and Transportation Authority, the key to success has been restructuring the design area because it has given a greater presence of urban planners in the design process. Similarly, in Hawaii, ongoing coordination across the Highways Division, including all district offices and branches, was cited as a significant contributor to its success. These issues of organization and communication are key to maintenance. Coordination between headquarters and districts is more important with maintenance than in design. In California, as described in the case examples, organizational changes have been made to better integrate maintenance staff into project design workflows. Integration and coordination among different departments and with districts is important for active transportation maintenance.
Several programs and new initiatives at FHWA are helping state DOTs and local governments improve upon policy, implementation, performance tracking, and making Complete Streets the default approach to roadway design. FHWA has launched various initiatives to support the inclusion of more connected, comfortable, and safer Complete Streets and assist DOTs in the evolution
of their respective Complete Streets programs. FHWA has also developed new funding programs for Complete Streets, as well as new guidance and tools, and delivered a detailed Complete Streets report to Congress in 2022.
It is important that the findings of this synthesis, and the best practices research being completed by different DOTs, local governments, MPOs, and universities, be used to stimulate discussion and prompt other DOTs to apply the transferable elements of the maintenance costs, equipment specifications, and training materials being developed in California, Maryland, and Washington State, and other states. Because this subject is little researched or discussed, it may be found that other resources are available and could be discovered in the coming years.
Future research needs can be summarized as follows:
The findings of this study highlight both the progress and challenges that state DOTs face in maintaining active transportation facilities. While leading states like California, Minnesota, and Washington offer promising practices, the need for better staffing, equipment, funding, and data management is apparent across the board. Coordination between state and local governments remains essential, as does the continued development of asset management systems and standardized maintenance protocols.
With support from FHWA initiatives and the evolution of Complete Streets programs, state DOTs are well positioned to address these challenges. The insights from this report will help agencies refine their approaches, foster collaboration, and develop sustainable maintenance strategies that protect their investments and enhance safety for all users. By building on these efforts, state DOTs can ensure that Complete Streets are not only well designed but also well maintained, contributing to vibrant, connected, and resilient communities across the nation.
