Extending Natural Bridge Road, from just west of Airflight Drive to Cypress Road, has been a top priority for the City of St. Ann for many years. To this end, the City of St. Ann, with the help of Congressman Lacy Clay, obtained federal funding to complete an environmental assessment of this project and selected the project team led by HR Green to complete the study.
The proposed extension of Natural Bridge Road will provide a much needed east-west outer roadway along the south side of Interstate 70 linking two existing interchanges: Cypress Road and Airflight Drive. The City of St. Ann, which is an inner ring suburb of St. Louis, has seen a reduction in tax base and property values in recent decades. For that reason, a primary goal of the Cypress I-70 Redevelopment Area Corridor Study is to stimulate redevelopment of underutilized properties that are located directly across I-70 from St. Louis Lambert International Airport. In addition, the project will enhance local traffic flow and circulation around the airport and includes the potential to develop a consolidated rental car facility within the corridor.
The project involves a conceptual design of the roadway alignment which includes a detailed traffic engineering element. The traffic engineering element defines the infrastructure needs such as signalization, turning lanes, roadway linkages, and pedestrian mobility. Since the roadway is envisioned as the catalyst for the redevelopment, it will be designed as a complete street, with all users in mind – including bicyclists, public transportation vehicles and riders, and pedestrians of all ages and abilities.
The project team for the Cypress Corridor Study is made up of the following team members: HR Green is the prime consultant; assisted by PGAV for land use and market analysis, planning and concept development, and funding implementation strategies; and Vector Communications for public involvements. Additional team members for the Corridor Study included Development Resource Partners for property acquisition and housing market analyses; Iteris Inc. for Travel Demand Modeling and other traffic-related work; and M3 Engineering Group for hydraulic engineering and studies.
