Legacy Place is a $200 million, 675,000 square foot open-air shopping, dining and entertainment center project that will contain more than 80 retail stores, restaurants, movie theaters, a bowling alley and billiard halls.

When a pedestrian bridge structure was needed to connect the parking garage to the movie cinema, WS Development and National Amusements worked together with Prellwitz Chilinski Associates Inc. (PCA Inc.) to choose a 48’ x 10, 40’ x 10’ and 27’ x 10’ Continental® Gateway® style truss bridge. This skywalk solution was chosen because it represented the ideal combination of constructability and cost efficiency. The pre- fabricated components were of good quality, and were able to be implemented more easily than building in place.

“We chose Contech for its competitive pricing and because it fabricated the structural truss offsite” stated Richard Askin, Director of Design and Planning with WS Development. “Having the structure produced offsite was helpful in reducing our onsite construction activities”

The main challenge of this project was achieving the desired clearance over the road while allowing for the sloped floors of the bridges and the skewed nature of the buildings that were being connected. The sloped floors were necessary to connect the different floor elevations of both buildings. This challenge was met by fabricating the center section of the bridge on a radius in order to allow the straight sections to meet the buildings perpendicularly.

In addition, the bridges were designed with a roof system and open sides which will later be enclosed with glass. Overhead lighting was included as well for safe passage at night.

“The bridge allows customers to park in the garage and then walk directly into the cinema lobby” said Richard Askin. “This is not only convenient for customers, but is an important component of our overall parking strategy at Legacy Place. It’s been very effective”
