Section 5 ZONE 2: OVERTOWN TO OMNI AREA 5.1 Introduction Zone 2 is the area east of the FECR line to NE 1st Avenue. The Splash continues on through Zone 2 as seen in the ground plane finishes of the skate and flexible use facilities. This zone between Overtown and the arts and museum area is a connective piece of urban fabric that provides a transition between the livable communities to the west and the public spaces to the east. This area provides an opportunity to reconnect the north and south sides of the Project to allow users of existing and future residential, retail and office developments in the downtown area to seamlessly walk, bike and drive between these emerging developments and within the context of a world-class open space venue. (Figure 5-1) To facilitate this cross movement, the Kiewit/Granite JV’s design eliminates the “earth plug” shown in the RFP concept, thereby opening up a vast pedestrian area in a location that would have otherwise been a massive physical and visual impediment to public access and safety. This enhancement creates newfound open space that is dedicated to active uses, such as a skate facility, event space, hard paved areas, new green passive recreation areas and public plazas. The Omni area is an ideal flexible space, which acts as a connecting element between the districts to the north and south.

5.2 Approach Structure The earth plug shown in the RFP concept has been eliminated, providing more open space along the street and creating a pedestrian- friendly zone. Spans are typically 225 ft. in length and the structural layout was carefully coordinated to align the piers to enhance connectivity and visibility and create natural portals that frame the local streets. Zone 2 features retaining walls for several of the ramps.

BASELINE The approach structures will meet the baseline requirements listed in Section 2.3 and exceed the requirements as shown.

ENHANCEMENTS The approach structures were developed in full compliance with the requirements of the Department’s Aesthetics Manual and Contract Documents. Our design enhances these requirements as shown: • Earth plug: Replaced with precast segmental box section bridge.

These improvements will not only create a connective open space opportunity for pedestrians and is equal to the existing city parks found in downtown Miami. The team has also secured letters of commitment from the City of Miami for bicyclists, but will also provide an abundance of proposed parking, which will at times serve as flexible open space for daytime and evening ongoing maintenance of site and landscape features for the Project’s public open space areas. These features include parking areas, events and pop-up venues. The improvements will provide safe pedestrian crossing between the downtown core and emerging residential pavements, playgrounds, lighting, public gathering areas and connective hardscape features that link all zones within the project boundaries. and retail/office spaces to the north.

6.4 Lighting The Wave is the most prominent feature of Zone 3, and our team’s proposed lighting solution is designed to enhance the ground plane activity as well as the grandeur of the Signature Bridge. The Signature Bridge portal lighting will consist of surface-mounted cylinder down-lights with low brightness to provide illumination on the Signature Bridge plaza without distracting from the color-changing wash of light on the bridge. The lighting solution is designed to minimize shadows and increase density of secondary lighting over the parking area and flexible use spaces to provide a high level of visibility. The lighting design also promotes movement through the landscape to connect the AACPA, Museum Park Metromover Station and future access north and south of the overpass (Figure 6-7 and Figure 6-8). Contemporary poles with low-glare, dark-sky-friendly, surge-protected, adjustable LED floodlights will “moonlight” the event and parking areas outside of the overpass. This solution is designed to meet illumination requirements while minimizing physical clutter and maximizing the space for tents and outdoor events. During light-sensitive events, the wireless control system will dim the zone of lights associated with the designated event space. Refer to Section 7 for Signature Bridge aesthetic lighting. BASELINE The Department’s Aesthetics Manual outlines several baseline requirements for lighting design as described below. Our design meets these requirements, and in many cases exceeds the requirements. • Baseline design elements will conform to the corridor-wide lighting specification Figure 6-7: Transition Span (Night) between Signature and Segmental Bridge (Night Rendering 12) Figure 6-8: 2nd Avenue Looking East (Night Rendering 13) previously listed in Section 2.5 and location of fixtures shown on Figure 6-9.

ENHANCEMENTS The lighting design was developed in full compliance with the requirements of the D epartment’s Aesthetics Manual and Contract Documents. Our design enhances these requirements in several areas: • Surface-mounted LED cylinder portal lights: Mounted continuously on the underside of the bridge to light the ground plane at night without taking attention away from the color-changing Signature Bridge below deck aesthetic lighting. (see Figure 6-10) • Increased density of secondary lighting: Provided for the pop-up retail and parking area under the overpass for increased illumination levels. • Adjustable accent lights: Mounted to poles to “moonlight” the event spaces and parking areas outside of the overpass. • Solar-powered, luminescent aggregate: Embedded into cast-in-place concrete walkways in strategic locations for an artistic effect as well as a safety feature for wayfinding. Exposure to sunlight for 10 minutes produces an afterglow of over 10 hours. • Color-changing lighting: Mounted continuously top-down at the embankment and abutment walls to wash wall coverings with light and compliment the Signature Bridge. Signature Bridge lighting enhancements are discussed in Section 7.3 Figure 6-9: Zone 3 Ground Plane Lighting Enhancements Figure 6-10: Signature Bridge Portal Lighting, 28 | KIEWIT • GRANITE Typical I-395 RECONSTRUCTION SECTION 6 | ZONE 3: OMNI TO MACARTHUR AREA

STRUCTURE ENHANCEMENTS The Wave Signature Bridge was developed in full compliance with the requirements of the D epartment’s Aesthetics Manual and Contract Documents. Our design enhances these requirements in several areas: • Anchor system fairing: A smooth edge fairing has been provided on the Signature Bridge to visually cover the suspender cable anchorages. • Access door: Provided at the bridge roadway level for improved security. • Arch inspection: Access is provided throughout the arch with a series of stairs and landings, as well as a hatch at the top of the arch. • Temporary piers: Enhanced erection method allows traffic on EB bridge in the interim phase before completion of the single unified structure supporting the twin roadways. • Concrete arch: Provides a smooth, uninterrupted surface, avoiding the bolts or splices that would be necessary with a steel arch design. • Constant-width structure: By removing the taper from the EB Connector from the Signature Bridge alignment, our design improves visual balance and symmetry. • Open ground plane: The Wave eliminates the piers east of Biscayne Boulevard by lengthening the arch structure, thereby eliminating all piers near Biscayne Boulevard. • Height: Important in creating this landmark bridge, the Signature Bridge soars to a height of over 250 ft. • Suspender cable spacing: Reduced from the concept wishbone arch design (with Figure 7-3: Signature Bridge at Biscayne Boulevard (Day Rendering 30) Figure 7-4: Signature Bridge and Plaza View towards Museum Park (Night Rendering 14) twice the number of cables provided), providing a stronger 3D experience for drivers on I-395 and a more unified visual waterfall of cables supporting the decks. • Extended service life: Our design exceeds the RFP requirement by 25 years to provide a 100-year service life for the Signature Bridge, achieved through our concrete mix design and concrete cover for the arch structure and bridge deck. • Constructability: The dimension of the box shape of our arch has been increased by 2 ft. to reduce congestion of post tensioning hangers and accommodate post tensioning and reinforcing steel. • Increased reinforcing strength: By allowing use of grade 75 rebar in areas of concrete arch rib, our design improves fabrication and concrete placement of the Wave. • Safety, Health, and Monitoring systems: Our team offers valuable experience designing and commissioning complex bridge Safety, Health, and Monitoring systems as demonstrated with our work on the Pearl Harbor Memorial Bridge in New Haven, CT.
