I-81 Viaduct Project

Project record

Brian served as traffic modeling lead for the $2.25 billion I-81 Viaduct Project from alternatives analysis and environmental review through final-design coordination. He developed and refined the project’s Vissim microsimulation framework, supported freight forecasting and construction-stage analysis, and helped shape the Community Grid alternative through operational concepts that distributed traffic, reduced widening, and limited property impacts. His work also included truck-routing analysis, public and agency coordination, surrogate-safety analysis, and high-fidelity visualization of proposed conditions.
