At its March 28 meeting, the O’Fallon City Council approved a resolution authorizing an Intergovernmental Agreement between the city of O’Fallon and the city of Dardenne Prairie for the I-64 Outer Road Project.
Via the agreement, both cities are to pay $40,000 each toward the $400,000 total cost of a study required to add a new south outer road and make changes to the north outer road along I-64. The St. Charles Road Board would pay the remaining $320,000, assuming they approve a Transportation Improvement Plan [TIP] application this July. If that happens and because
Since the design associated with the project will not occur until 2020, the $40,000 expense will be included in O’Fallon’s 2020 budget.
Under O’Fallon Ordinance No. 6311, the city entered into an agreement with St. Charles County to use St. Charles County transportation sales tax funds [Road Board funding] for the I-64 South Outer Road Study. The study concept was to provide a new south outer road along I-64 and convert the north outer road to one-way, westbound from Route 364 south to Hwy. DD. The study cost was $250,000, of which the St. Charles County Road Board provided 80 percent, or $200,000 through the transportation sales tax. The Road Board will make recommendations for approval of applications in July 2019.
The city contracted with Horner and Shifrin to complete that study, during which O’Fallon coordinated with Dardenne Prairie, Lake Saint Louis, MODOT, the Federal Highway Administration, and St. Charles County. Using all input and comments, study results were released in March 2019. All improvements recommended in the study are located within the city limits of O’Fallon and Dardenne Prairie.
