The study focused on the change in travel patterns to and from the seaport after the PortMiami tunnel opened. In addition to a quantification of changes in travel demand and travel patterns, the study focused on the infrastructure improvements necessary to ensure long term mobility for freight in the region. As part of this study, the team collected traffic data at numerous intersections and links from the Miami River to I-395 and east of I-95. This data collection included 72-hour link counts, 8-hour turning movement counts at intersections and a 7-day count of the Port bridge to estimate the magnitude of trucks carrying hazardous materials. Short-term and long-term improvements were identified to provide an alternate access to PortMiami to complement operations of the Tunnel.
