Caution urged as road construction continues in St. Peters, Cottleville

St. Charles County residents are being asked to drive cautiously and warned of traffic delays as construction on major road projects in Cottleville and St. Peters continues.

In St. Peters, work was expected to begin on May 17 to widen Mid Rivers Mall Drive at its interchange with Interstate 70. The project is expected to be completed by the end of September.

The project will add a traffic lane on both the southbound and northbound portion of Mid Rivers Drive on the overpass across I-70. Additional northbound and southbound lanes will be added to Mid Rivers Mall Drive from the I-70 North Outer Road to Ecology Drive.

The project also calls for a traffic signal to be removed and replaced on the North Outer Road intersection with Mid Rivers Mall Drive. Existing railroad crossings north of the outer road will be modified. A multi-use pedestrian and bicycle trail will be added on the west side of Mid Rivers Mall Drive.

The $1.66 million road project will get 60 percent of its funds from the county’s half-cent transportation sales tax approved by voters in 2007.

City officials say work for this project will begin in the traffic islands and on traffic signal improvements at the I-70/Mid Rivers Mall Drive interchange, before proceeding north of the I-70 interchange to Ecology Drive.

Meanwhile in Cottleville, a portion of Hwy. N will be closed for about three days, beginning this week, weather permitting. It is the first in a series of road closures.

Closing the highway in May will allow two pipes crossing the highway to be replaced. MoDOT hopes to have the highway reopened before the Memorial Day weekend.

A second major Hwy. N closure is planned for June 1, when a portion of the roadway at Eagle Hill Drive is planned to be closed for two months to replace a box culvert. That project extends from Weiss Road to Eagle Hill Drive. The project will include a new center lane and a raised roadway to reduce flooding on Hwy. N.
