I-595 Corridor Improvements

This project extended 10.5 miles along I-595 from the I-75/Sawgrass Expressway interchange to the I-595/I-95 interchange in central Broward County. The scope consisted of the reconstruction/addition of auxiliary lanes and resurfacing of the I-595 mainline. This included associated improvements to frontage roads and ramps, as well as a new reversible express lanes system in the I-595 median.  FR Aleman developed and analyzed Maintenance of Traffic lane closures for the entire project.  This involved the development of lane closure worksheets, as required by the Plans Preparation Manual. FR Aleman was also involved with the design of the ITS infrastructure, which included conduit for ITS devices and Electronic Toll Collection (ETC) components and service points to all permanent I-595 ITS that supported traffic management and operations of the general purpose and express lanes. This network included subsystems for reversible express lane access control, CCTV traffic monitoring, DMS, changeable message sign, HAR, Microwave Vehicle Detection Station, as well as ETC infrastructure which involved all ancillary components within the corridor. This complex project benefited the client by reducing excessive delays along I-595 in Broward County.

FR Aleman has also provided Power Design services and served as the Engineer of Record responsible for all design aspects and preparation of construction plans and specifications for this project. FRA was responsible for specifying the conductors, generators, transfer switches, transformers, disconnect switches and all associated electrical equipment to serve all ITS equipment, except for the toll gantry and equipment building.

Additionally, FR Aleman provided SUE services to support the design and construction for approximately 15.5 miles of the interstate highway system.  FR Aleman provided designation of all requested underground utilities by means of electromagnetic and ground penetrating radar (GPR). Additionally, FR Aleman provided utility locations using the vacuum excavation method for approximately 1,500 possible utility conflicts. FR Aleman was required to complete all required SUE work within the first six months of the design.
