VALLEY PARK, MO (KTVI) - MoDOT is about to start big time changes to a major southwest St. Louis County interchange and intersections nearby.
Some of the biggest changes are happening right around Highway 141 and Interstate 44. There will also be work going on at two 141 intersections further to the north.
MoDOT hopes the changes will improve the flow of the traffic in this area and help reduce the significant back-ups that can take place.
Among the most significant changes is a flyover ramp that is planned from Highway 141 south to eastbound I-44. There are also other changes to get on and off I-44 west and from Highway 141 north and south.
There are also changes coming to how drivers make left turns from Highway 141 onto Marshall Road and from 141 onto Vance Road.
MoDOT is going to use what`s called signalized through turns, meaning drivers will actually go past Marshall and Vance then loop around using an outside lane at the signals to make the turns onto those roadways.
Although the project is designed to reduce traffic back-ups, MoDOT says there will also be improved drainage to help reduce flooding in the Highway 141 and Interstate 44 area. There has been a problem with flooding in that area for years. The most recent incident was back in December when historic flooding along the Meramec swamped Highway 141 and I-44.
MoDOT is going to hold a public meeting on this project this coming Wednesday from 4 p.m. until 7 p.m. at the Field House at Valley Park High School. Construction is slated to start next month and continue until July of 2018.
