City Council Agrees to Cost Sharing For I-70 Corridor Study

agreed to contribute $50,000 to a study that will take a look at ways to improve traffic flow, reduce congestion and examine other issues along the I-70 corridor at last Thursday’s meeting.

The council voted 7-1 to approve entering the intergovernmental agreement with St. Charles County, in partnership with other local cities and Great Rivers Greenway.

Ward 4 Councilman Jeff Schwentker voted against the bill. Ward 1 Councilwoman Rose Mack and Ward 3 Councilman Rick Battelle were absent.

According to the agreement, the Federal Highway Administration will partner with Missouri Highways and Transportation Commission to complete the $375,000 study of the western corridor, from I-270 in St. Louis County to Lake Saint Louis.

In addition to O’Fallon’s $50,000:

• Wentzville would contribute $50,000
• St. Peters would contribute $50,000
• Great Rivers Greenway would contribute $50,000
• Lake Saint Louis would contribute $25,000
• St. Charles County would provide $100,000

The corridor study will include information from other local studies, including the 2011 East West Gateway Council of Governments Regional Transportation Plan 2040.

The studies recommended interchange and lane improvements in St. Charles County including: 

• Interchange improvements at Zumbehl Road, Cave Springs Road, Mid Rivers Mall Drive, Salt Lick Road, Route K and Bryan Road
• The extension of Wentzville Parkway
• Lane additions and upgrades to the interstate between Highway 94 and MO Route T
