Examining the Transportation Impacts of the PortMiami Tunnel presented by Paul O’Rourke December 7, 2016 Presentation Overview • Introduction • Objective • Impacts on Truck Counts 2013-2015 • Impacts on Travel Speeds 2013-2015 • Simultaneous Increase in Truck Counts and Travel Speeds • I-395 Reconstruction Project • Conclusions Introduction • Opened to traffic on Sunday, August 3, 2014, the PortMiami Tunnel is expected to improve traffic flow in downtown Miami by reducing the number of cargo trucks and cruise related vehicles on congested downtown streets. • The tunnel connects the MacArthur Causeway to Dodge Island, providing direct access between the port and highways I-395 and I-95, creating another entry to PortMiami in addition to Port Boulevard. • The PortMiami Tunnel will provide an additional benefit by accommodating traffic associated with the recent Panama Canal expansion and the arrival of larger post-Panamax ships into the port. Source: www.portofmiamitunnel.com Objective • This study examines the impacts on truck counts and travel speeds in downtown Miami resulting from the opening of the PortMiami Tunnel. The study utilizes tabular and spatial data provided by FDOT and the HERE National Performance Management Research Data Set (NPMRDS). Using geographic information systems (GIS) technology, these data sources are merged together spatially to create value-added information. • Optimally, the system will experience fewer trucks traversing downtown Miami streets and more trucks utilizing the I-395/MacArthur Causeway in order to reach PortMiami. Simultaneously, the system may experience differences in travel speeds as a result of a decrease/increase in truck volumes along some facilities. • For the purposes of a before-and-after analysis, and since the tunnel was opened in 2014, data for truck counts and travel speeds were used from the years 2013 (before the tunnel opened) and 2015 (after the tunnel opened).

These facilities include: • NE 2nd Avenue NB from the I-395 EB ramp to NE 12th Street. • MacArthur Causeway EB from the causeway origin to Fountain Street. • The I-395 EB ramp from I-95 to N. Miami Avenue. • The I-395 EB ramp to NE 2nd Avenue. I-395 Reconstruction Project FDOT is nearing the implementation of an I-395 reconstruction project, scheduled to begin in 2017. Part of the project involves the rebuilding of the I-395 corridor from the I-95/Midtown Interchange to the MacArthur Causeway. The project web site is http://www.fdotmiamidade.com/i395designproject Conclusions • An examination of truck counts and peak hour travel speeds throughout the study area between 2013 and 2015 has revealed the following notable impacts since the opening of the PortMiami Tunnel: o A decrease in truck counts throughout most of downtown Miami, including a substantial decrease in trucks along Port Boulevard. o An increase in truck counts along I-95, I-395, and the MacArthur Causeway. o A decrease in travel speeds along I-95 and I-395, both directions. o An increase in travel speeds along the Dolphin Expressway (westbound), the MacArthur Causeway (eastbound), and Biscayne Boulevard (both directions). o A simultaneous increase in truck counts and travel speeds along a portion of NE 2nd Avenue (northbound), the MacArthur Causeway (eastbound), and two I-395 eastbound ramps. • With the pending implementation of the I-395 reconstruction project, coupled with the PortMiami Tunnel, the future of truck movement, and congestion in general, looks positive in the vicinity of PortMiami.
