Key takeaways from AASHTO Committee on Bridges and Structures: Navigating overweight vehicle movement in urban areas. August 5, 2026 As the nation's capital, Washington, DC, presents a uniquely complex transportation and infrastructure environment. The region must accommodate a diverse range of users, including residents, commuters, tourists, government agencies and commercial operators, all of whom place varying demands on the transportation network. These demands are further complicated by the movement of commercial freight, federal and security-related vehicles, and large-scale ceremonial and special events that require careful traffic and load management. Adding to these challenges is the District's extensive inventory of historic bridges and structures. Many of these assets were designed under earlier engineering standards and feature complex structural systems that require specialized evaluation to accurately assess their load-carrying capacity. Preserving these critical structures while ensuring public safety and maintaining mobility requires innovative engineering approaches and data-driven decision-making. At the 2026 AASHTO Committee on Bridges and Structures Annual Meeting, EXP's Senior Director of Structures and Bridge, Morteza Rahimi Abkenar, PhD, PE, joined Kamal Elnahal, PhD, PE, and Hongting Zhao, PE, of the District Department of Transportation (DDOT), to discuss the challenges and solutions associated with managing overweight vehicle traffic in constrained urban environments. The presentation highlighted strategies used to balance infrastructure preservation, operational needs and transportation efficiency, while addressing the unique challenges posed by Washington, DC's historic bridge network and densely developed urban landscape. Permit evaluation processes and solutions To support the safe movement of goods, equipment and specialized vehicles throughout the District, DDOT issues permits for oversize and overweight vehicle travel, often requiring detailed engineering evaluations to verify that bridges, tunnels and other transportation assets can safely accommodate the proposed loads. As a trusted partner to DDOT, EXP plays a central role in this process by providing rapid, data-driven structural assessments that help balance infrastructure preservation with operational needs. EXP's streamlined evaluation approach enables timely permit reviews, often under accelerated schedules, by screening vehicle configurations, identifying affected assets along proposed routes and assessing available structural capacity information. When a permit request exceeds established thresholds, EXP performs detailed structural analyses to determine whether the vehicle can be safely accommodated and, when appropriate, recommends operational controls such as speed restrictions, designated travel times, escort requirements or alternative routes. EXP's partnership with DDOT on transportation projects EXP is proud to partner with DDOT in preserving and enhancing the safety, reliability and resiliency of Washington, DC's transportation infrastructure.
