Benesch I-74 Corridor Landscape Concepts

Challenge

Shive-Hattery has been part of the public involvement process for the seven-mile stretch of the Interstate 74 corridor in Bettendorf, Iowa and Moline, Illinois. The process consisted of ensuring all stakeholders had the opportunity to come to a community-wide consensus on targeted issues and areas. An advisory committee was formed which included staff from the cities of Bettendorf, Moline, and Davenport; elected officials; staff from Scott and Rock Island counties and staff from the Iowa, Illinois; and Federal Departments of Transportation. Refining existing styles to implement the new design of this project required Shive-Hattery to focus attention on many aspects including pedestrian railings, bridge abutments, bridge piers and lighting, fences, barriers, retaining walls, sound walls, and color treatments. While these features seem small on their own, together the character of the entire project is visible.

Solution

Shive-Hattery provided aesthetic design elements providing identify elements to unify the corridor as it passes through several communities. 3-D design visualization helped to communicate the intent and allow the Departments of Transportation to evaluate the designs and make informed decisions to implement Shive-Hattery’s master plan. Creating renderings of lighting effects; vehicle and pedestrian bridge views across the river; overpasses from different angles; a letdown elevator structure and plaza space; bike/pedestrian paths along the river’s edge; and natural spaces produces a strong visual interpretation before the project construction ever began. Shive-Hattery was instrumental in defining urban park areas that would otherwise have been left as unused space. This area has now become a pedestrian destination with stormwater management integrated into a canvas of decorative rock, textures and plantings to provide welcoming gateways into the communities of Bettendorf and Moline.

Impact

By creating an aesthetic and pleasing identity for the Interstate 74 Corridor and Bridge the natural beauty of the surrounding area will be emphasized. Shive-Hattery played an important role in establishing designs that will unify the Quad Cities corridor, creating a welcoming environment for the surrounding communities as well as interstate travelers. By proposing sustainable site solutions that met water quality goals as well as aesthetic design goals, the Iowa DOT funded the planting enhancements saving the City of Bettendorf over $500,000.
