(KMOV) -- Traffic on I-70 at Mid Rivers Mall Drive and Highway 79 is often at a standstill during the rush hour. St. Charles County and St. Peters are working on plans to alleviate traffic at those bottlenecks.
"This bottleneck, here, is the source of half the frustration in St. Charles County, " said Steve Ehlmann, St. Charles County Executive.
The county and city of St. Peters are partnering to apply for state and federal funds to make changes to the Highway 79 and Mid Rivers Mall interchanges and add a west-bound service road, north of the interstate.
The local groups are applying for a cost-sharing program with MoDOT and a federal grant through the East-West Gateway Council.
Construction of a new diverging diamond interchange at Mid Rivers Mall Drive, changes to the Highway 79 interchange, and construction of a new collector road will cost an estimated $15 million.
A MoDOT spokesman said MoDOT has not yet seen the plans. St. Charles County plans to submit an application for state funds by this Friday.
East-West Gateway Council Division Manager, Jim Wild, says the grant that the group is seeking is competitive. The application is due October 29th. The council expects to have a decision by the end of the year.
If the funding comes together, St. Charles County says the project could start in late 2013 and last a year.
