Purpose: With the D-B Concept, the project’s purpose remains the same as in the RFP Concept which is to modify the existing system-to-system connection between I-595 and I-95 by providing direct connections between the I-95 Express Lanes and the General Use and Reversible Express
Lanes on I-595. The proposed design modifications will further the expansion of the South Florida Regional Express Lanes Network improving travel reliability and long-term mobility options for South Florida commuters.
Need: The need for the proposed improvements is consistent with the needs enunciated in the I-595 PD&E study and the approved I-95 Express PD&E Study with respect to:
• System Linkage: I-595 Reversible Express and I-95 Express are manifestations of FDOT’s vision to build an interconnected regional system of express lanes in Southeast Florida. The RFP Concept was intended to complete the connectivity between these two express
lane systems with the objective of addressing long-term capacity needs, mobility needs and realizing improvements to travel reliability along both the I-595 and I-95 corridors. The new D-B Concept is consistent with the original objective and is anticipated to improve weaving lengths within, and through the area.
• Emergency Evacuation: I-595 is a critical artery which facilitates movement of traffic during emergency evacuation periods as part of the emergency evacuation route network designated by the Florida Division of Emergency Management. It connects other major arterials and highways designated on the state evacuation route network within the project limits, such as I-95 and Florida's Turnpike. The RFP Concept was intended to facilitate enhanced emergency access and incident response times. Changes proposed as part of the D-B Concept are not anticipated to affect emergency evacuation and are likely to improve emergency response during congested periods compared to the RFP Concept.
• Multi-Modal Transportation System: The RFP Concept was consistent with state and local government policy of promoting multi-modal transportation systems. Connectivity between the I-595 and I-95 express lanes systems will facilitate expansion of the current/planned express bus and bus rapid transit systems throughout the region. It will also provide increased travel options for users of both the I-595 and I-95 corridors. These increased travel choices will ultimately help in managing and accommodating the long term travel demand needs in the county. Changes proposed as part of the D-B Concept are not anticipated to affect the consistency with these policies and increased travel options.
