<br />836 (Dolphin Expressway), approximately seven (7) miles. The PD&E Study proposed corridor improvements that added highway and interchange capacity by implementing an express lanes system and interchange improvements, new alignments and new Pavement Markings. The PD&E Study evaluated the following potential types of improvements: Implementation of dynamically priced express lanes; Access and ramp connections to and from the express lanes (ingress and egress access points); Interchange improvements – Modifying existing entrance and exit ramps serving the interchanges within the project limits; Intersection improvements – Widening and turning lane modifications along the crossing roadways to facilitate the ramp modifications and improve the access and operation of the corridors upstream and downstream from the interchanges.
<br />FDOT D4, Interstate 95 (I-95) PD&E/SIMR Study, Interchange, and Intersection Improvements, Broward County, FL | Project Engineer - Conducting a PD&E Study and Systems Interchange Modification Report (SIMR) for a section of Interstate 95 (I-95) from south of Hallandale Beach Boulevard (SR 858) to north of Hollywood Boulevard (SR 820), approximately three (3) miles. This study evaluates the potential modification of existing entrance and exit ramps serving the three interchanges within the project limits. Pavement Markings, widening, and turn lane modifications are also being assessed along Hallandale Beach Boulevard, Pembroke Road, and Hollywood Boulevard to facilitate the ramp modifications and improve the access and operation of the corridors upstream and downstream from the interchanges.
<br />FDOT D2 & D5, I-75 (SR 93) Corridor Planning Study, Feasibility Study, Sumter, Marion, Alachua, Columbia and Suwannee Counties FL | Project Engineer - The feasibility study was to add corridor and interchange capacity. Evaluate express lanes, general-use lanes, and auxiliary lanes. The study focused on three areas: 1) D2 & D5 corridor typical section evaluation; 2) D2 & D5 Truck operations; and 3) 13 Interchange improvements in D2, which involved one system-to-system and 12 service interchanges.
<br />FDOT D2, I-295 (SR 9A) Western Beltway Corridor Planning Study, Express Lanes Feasibility Study, Duval County, FL | Lead Designer - Responsible for the conceptual design of express lanes new alignment and pavement markings, cost estimating (LRE) and the evaluation of the feasibility of several concepts in order to move forward to the PD&E phase(s). Concept development included 3 system-to-system and 15 service interchanges.
<br />FDOT D6, SR 826 East/West PD&E/SIMR Study, Add Express Lanes, Miami-Dade County, FL | Lead Designer - Responsible for the addition of express lanes and/or additional general-purpose lanes, which included highway design, complex conceptual design, interchange design, new pavement markings, plans preparation, cost estimating (LRE), alternative selection, developing safety improvements and report generation. Concept development included 2 system-to-system and 6 service interchanges.
<br />FDOT D4, I-95 PD&E Study, Add Express Lanes (Phase 3), Broward and Palm Beach Counties, FL | Lead Designer - The PD&E Study was initiated as part of the planning process to evaluate the implementation of two tolled express lanes in each direction to alleviate the current traffic conditions, address mainline capacity issues, and implement interchange modification solutions to the Interstate 95 (I-95) corridor. The study limits were south of Commercial Boulevard in Broward County to south of Glades Road in Palm Beach County. Interchange improvements were identified during the I-595/ I-95 Master Plan Study and the need for express lanes in the I-95 Corridor Planning Study. The project was approximately 13.7 miles long. The study addressed existing and projected operating deficiencies along this section of I-95, including mainline capacity, interchange geometry, new pavement markings, and ramp terminals. The study area exceeded the minimum standards of FDOT Level of Service (LOS). I-95 has a functional classification of urban principal arterial-interstate.
<br />FDOT D6, SR 826 North/South PD&E Study, Add Express Lanes, Miami-Dade County, FL | Lead Designer- Responsible for the addition of express lanes and/or additional general-purpose lanes, which included highway design, complex conceptual design, interchange design, new pavement markings, plans preparation, cost estimating (LRE), alternative selection, developing safety improvements and report generation. Concept development included 1 system-to-system and 6 service interchanges.
<br />FDOT D6, I-75 PD&E/SIMR Study, Add Express Lanes, Miami-Dade County, FL | Lead Designer - The PD&E Study evaluates various improvements within the I-75 corridor in Broward and Miami-Dade Counties. The improvements consist of the potential addition of reversible, managed, express, and auxiliary freeway lanes, new service interchanges, existing interchange improvements, new pavement markings, and a new Bus Rapid Transit (BRT) route. These improvements were combined to constitute several alternative concepts for the I-75 corridor. These improvements were needed to address future vehicular growth projected in the area, enhance hurricane and other emergency evacuations, and improve system connectivity between I-75, SR 826, Gratigny Parkway (SR 924), Homestead Extension of Florida’s Turnpike (HEFT/SR 821) and I-595.
