The Florida Department of Transportation (FDOT), District 4 recently developed an Interchange Master Plan (IMP) for Broward County to address the traffic and safety issues at the 16 interchanges along Interstate 95 (I-95) within the County. The primary objectives of the IMP were to assess the existing and potential future deficiencies and identify short-term and long-term improvements prioritized for phased implementation. The I-95 Interchange at Sunrise Boulevard (SR-838) was one of the 16 interchanges studied in the IMP. An Interchange Concept Development Report (ICDR) was prepared to evaluate the specific issues associated with the current configuration and a Concept Plan was developed to improve the traffic operations at the interchange.
The ICDR also recommended a Project Development and Environment (PD&E) study for the interchange. However, due to the potential impact of the Woodlawn Cemetery located on the Southeast quadrant of the interchange, the PD&E project was divided into two parts. The east side of the interchange would be included in the I-95/Broward Boulevard interchange PD&E study, and the west side of the interchange would advance directly to the design phase since the improvements identified in the ICDR did not require a PD&E study. The objective of the study is to provide the design team with recommended design concepts to improve the operation of the I- 95 southbound ramps and the ramp terminal on the west side of the interchange.

The purpose for preparing the Interchange Operational Analysis Report (IOAR) is to document the traffic analysis performed for the west side of the I-95/Sunrise Boulevard interchange with more recent data, and seek approval of the southbound ramp terminal ultimate 2040 modifications supporting the design project (FM # 433514-1). The project has been programmed by FDOT into the work program based on the improvements identified in the ICDR. According to the ICDR, the I-95/Sunrise interchange currently operates at Level of Service (LOS) D or better for all freeway segments except for the southbound weaving segment between I-95 SB On-Ramp from Sunrise Blvd to I-95 SB Off-Ramp to Broward Blvd south of the interchange, which operates at LOS F during both the AM and PM peak periods. All intersections on Sunrise Blvd near the interchange, including the I-95 SB Off-Ramp Terminal, I-95 NB Off-Ramp Terminal, NW 16th Ave, and NW 24th Ave as a whole operate at LOS D or better.
There is no spillback to the I-95 mainline through lanes from either the SB Off-Ramp or the NB Off-Ramp. However, the analysis and field observations reveal significant delays in certain movements. This is particularly true for southbound left- and right-turns from I-95 SB Off-Ramps to West Sunrise Blvd where the individual vehicles experience significant delays in both AM and PM peak periods. With the growing traffic in the area, the conditions will continue to deteriorate through year 2040.
