This document discusses plans to improve transportation along I-66 inside the Beltway through 2040. It proposes implementing dynamic tolling, expanding transit services, improving bike/pedestrian access, transportation demand management programs, and integrated corridor management. Future widening of I-66 is also proposed. The project aims to move more people through the corridor by reducing congestion and increasing travel options. Public outreach will begin and a traffic/revenue study and NEPA process are the next steps.
