City of Moline
The City of Moline, Illinois chose a 270 foot pedestrian overpass to connect the second level of the city parking structure with The Mark of the Quad Cities Civic Arena. The structure has a minimum clear height of 21’-10” at River Drive and is comprised of structural tube-steel trusses supported by concrete piers on drilled shaft piles. Three of the four concrete piers are “hammer-head” style. To avoid conflict with existing streets, drives, sidewalks, parking lots and building entrances, the walkway has three minor changes in direction.
To provide an aesthetic connection to The Mark, the walkway is enclosed with a glass curtain wall system, the same curtain wall system that is in place at the arena. The signature green tinted visual and spandrel glass that is used throughout The Mark was also used on the walkway. To maximize visibility inside and outside, visual glass extends from floor to ceiling, giving pedestrians inside the walkway a wide perspective of the area around The Mark. From the outside, the glass allows for the rhythm of the trusses to be evident. Utilities, roof drain piping and other systems are located in the spandrel glass areas. On the inside of the walkway, this same area is covered with abuse-resistant gypsum board.
