Introduction 1.0 Introduction This Supplemental Report documents findings from continuing refinement analyses associated with the I-66 Multimodal Study after the June 2012 release of the Final Report. Building on the projects in the region’s Financially Constrained Long-Range Plan (CLRP) and additional improvements recommended by the I-66 Transit/TDM Study, the I-66 Multimodal Study con- sidered a wide range of complementary and mutually supportive multimodal improvement options that could be implemented to mitigate congestion and improve mobility along the I-66 corridor inside the Beltway. Among the options explored were expanded public transportation, additional highway lane capacity, enhanced transportation demand management (TDM), high- occupancy
