ST. LOUIS – Even though winter isn’t quite in the rear-view mirror in St. Louis, MoDOT construction teams and contractors are already looking at the road ahead for roadway construction this year.
Some of the anticipated work will start as early as the first few weeks of March, so MoDOT is sharing information on the projects within the greater St. Louis area that will have significant impacts on daily travel. These projects will have lane closures, often around the clock, and may have narrowed and shifted lanes.
“We have several projects along the I-44 corridor – from the Mississippi River all the way out to the Crawford County line. Two of them – the bridge replacement near Shrewsbury and the bridge work between Kingshighway and 39th Street in St. Louis City – will have very large impact on travel into and through the St. Louis City area. Like last year, we encourage drivers, especially along I-44, to review their options. Some may be able to adjust the time of their commute, or even telecommute several days a week. Others may want to consider alternate routes to get around the construction. For others, using ride-sharing, carpooling or transit options may be the best choice. We are sharing this information now so motorists know where the most impacts to traffic are expected so they can be prepared and consider what option works best for them as early as possible,” said MoDOT St. Louis District Engineer Tom Blair.
MoDOT projects expected to have the biggest traffic impact to motorists in and around the St. Louis region this year are:
