ST. PETERS, MO (KTVI)-A major construction project designed to improve a busy St. Peters interchange at Mid Rivers Mall Drive and I-70 is starting Wednesday. The project is going to widen Mid Rivers at 70.

Project organizers say the goal is improve safety and reduce congestion.

St. Peters officials say crews are going to add a traffic lane to both northbound and southbound Mid Rivers where it goes over 70. An additional lane in each direction will also be added to Mid Rivers from the I-70 North Outer Road to Ecology Drive, which is just north of that location. Project organizers say the work today is beginning with the traffic islands and traffic signals at the main interchange.

Parts of the islands will eventually be removed and improvements will be made to the signals. A traffic signal will also be removed and replaced at the North Outer Road intersection, a nearby railroad crossing will be modified and a multi-use pedestrian and bike trail will be added.

The project is costing more than $1.6 million and is expected to be completed by the end of September.

St. Peters officials say 60% of the cost is being covered through a St. Charles County Road Board grant-the rest is being paid for by the city of St. Peters.

There will be some lane closures with this project but those won`t happen until this summer.
