BUCKHEAD PARK OVER GA400 96 09/23/16 | ROGERS PARTNERS Architect+Urban Designers CONCEPT STUDY - PART 1 unknown (construction cost) 8.2 acres (357,200 sqft) I-696 Pedestrian Plazas Designer: MDOT Year completed: 1989 Location: Oak Park, MI Length: A set of three 700 ft long bridge decks Width(s): 170 ft (width of highway) A set of three landscaped plazas were incorporated into the design and construction if I-696, forming the tunnels through which the highway passes. These structures are a set of three 700-foot-wide bridges that cross the freeway within a mile. They allow members of the Jewish community to walk to synagogues on the Sabbath and other holidays when Jewish law prohib- its driving. These plazas had their length limited; if they were longer they would be considered tunnels that would require ventilation systems. BUCKHEAD PARK OVER GA400 97 PRECEDENT RESEARCH $6.8M (construction cost) 0.15 acres (6,400 sqft) $1,063/sf Melkwegbridge Designer: NEXT Architects; Rietveld Landscape Year completed: 2012 Location: Purmerend, Netherlands Length: 330 ft for bicycle pathway; 150 ft for pedestrian pathway Width(s): 12 ft for bicycle pathway; 16 ft for pedestrian pathway A steeply arching upper level for pedestrians and a zig-zagging lower level for cyclists and wheelchairs. One bank is higher than the other, so to achieve the gentle slope required for bicycles and wheelchairs, the team needed to create a 330-feet-long pathway. They decided to also create a shorter route for pedestrians that offers a high viewpoint. At 40 ft high, this arch is high enough to allow boats to pass beneath and the lower deck splits into two parts that revolve open when boats are approaching. The pedestrian bridge weighs 85 tons, consists of 130 steps and is supported by a steel arch.

BUCKHEAD PARK OVER GA400 99 PRECEDENT RESEARCH $5M (construction cost) 0.2 acres (8,700 sqft) $575/sf Buffalo Bayou Park Rosemont Bridge Designer: SWA Group Year completed: 2011 Location: Houston, TX Length: 500 ft for one bridge, 300 ft for second bridge Width(s): 10 ft The Rosemont Bridge is a pedestrian and bicycle bridge connecting SWA Group’s newly de- signed Buffalo Bayou Park to nearby neighborhoods, crossing over the waterway and the Me- morial Drive. It creates a new tree-top view of Houston’s downtown skyscrapers. The 780 foot long bridge is composed of seven structural sections with the heaviest being 35,000 pounds. The bridge sections were hoisted into place by 300 and 700 ton cranes and sit in concrete col- umns/bents supported by 40 feet deep drilled piers of 48” and 60” diameters. 105 cubic yards of concrete were poured in place to create the bridge deck.

Designed as a retreat rather than a public promenade, the park features zigzagging paths and extensive structural concrete walls and fountains. Trees and shrubs were selected and sited to work in concert with the waterfalls, in an effort to minimize the constant din of the highway below the park and the city just beyond its walls.

This highest point commands a view of Mt. Fuji. The Shuto Express- way Ohashi Junction, on which the roof garden sits, is a building shaped as a Coliseum which all the cars can make a circle inside and that connects to the different lines of highways.

Crosses the Seine, connecting the Parc de Bercy and the Bibliothèque National de France, providing a variety of views of historic Paris. Its center span crosses the river without need for external support, relying on its center arch combined with the suspended catenary below. The intersection of the two catenaries forms a plaza on the lower level measuring 1,200 sq m. It was assembled as a single unit off-site and brought and installed directly off of its delivery ship.
