This Design/Build/Finance project consisted of converting the single HOV lane on I-95 into two high occupancy toll (HOT) managed lanes in each direction (Northbound and Southbound) by tapering the travel lanes from 12 feet to 11 feet from approximately South of the NW 32nd Street bridge to North of the SR 826 (Golden Glades) interchange, inclusive of the SR 112 Interchange. Due to the narrow passages for I-95 at the interchange with SR-112, considerable structural modifications were needed for the final configuration. The work scope consisted of the design and construction of all roadway and bridge elements, including jacking of existing bridges to higher elevations, relocation and/or strengthening of bridge pile caps, piers and pier caps, lane transitions, concrete pavement, pavement markings, drainage, retaining walls, traffic railings and landscape. The project also included modifications to existing signage, lighting, and installation of several of sign and toll gantry structures as part of the implementation of the Managed Lanes in both directions. Beyond the bridge and roadway components of this project, this innovative project employed tolling and Intelligent Transportation Systems (ITS) to manage the variable price toll lanes which included dynamic message signs (DMS), closed circuit television (CCTV) cameras where necessary to include coverage of new DMS, microwave vehicle detection systems (MVDS), replacement of existing VDS with self-calibrating microwave vehicle detection stations (MVDS), communications system and connectivity to the existing I-95 fiber optic. New toll equipment and toll equipment building(s) were designed and installed, inclusive of a toll equipment fiber optic communication platform using existing and proposed I-95 and SR 836 fiber infrastructure.
Responsibilities included coordination amongst numerous stakeholders and public agencies, management of the design submittal and review process, construction management, schedule analysis, materials testing and certification, project reports, ITS and Toll Systems testing, shop drawing and RFI reviews and certification of monthly payments to the Design-Build Firm. BCC personnel reviewed all the contractor’s required submittals, such as shop drawings and product cut sheet approval. Our team was also accountable for ensuring that the contractor met all the project timelines and milestones as established by Florida Department of Transportation, as well as providing proactive coordination of all construction activities and their impact on the public and/or adjacent Projects.
