This clarification comes from Tom Drabelle, O'Fallon's Director of Public Information: "This is actually a St. Charles County project, not an O’Fallon project. Although O’Fallon is involved and will be involved in the public education and planning process. The County will be building the new roadways, managing construction, etc. They are the driving force through this project as it’s intended to improve traffic flow and increase access to businesses and residents throughout the entire County."
The St. Louis Post-Dispatch reported this week that one-way outer roads on I-70 could be coming to O'Fallon in the future.
St. Peters has made changes to its plan for one-way outer roads in order to allow better access to Route 370, and St. Peters residents will have the chance to comment at an open house this week.
O'Fallon has not yet released their own plans for one-way outer roads, but the Post quoted O'Fallon's Director of Public Relations, Tom Drabelle, who said that the city would have to build a new roadway in one spot where there is currently no south outer road, and also that the city would consider constructing "Texas U-turns" to allow access from one outer road to the other.
Once O'Fallon's plans are released—possibly by the end of the year—residents will be asked to give their input.
The St. Peters part of the one-way configuration could cost $12-15 million, and the O'Fallon part as much as $25 million.
