MoDOT is set to start more work on Interstate 44, prompting them to encourage drivers who use the interstate to commute to downtown St. Louis to search for an alternate route, especially during rush hour.

The shift eastbound I-44 traffic in St. Louis City has been rescheduled to Friday, April 13 as part of the continuing work to renovate or replace several bridges.

After the morning commute April 9, MoDOT was supposed to move three lanes of eastbound I-44 traffic between Tower Grove Ave. and Grand Blvd. onto the westbound lanes. Crews were also expected to close 39th St. sometime April 10. Both of these projects were delayed due to recent weather.

These new lane shifts and closures are the latest updates in the massive I-44 projects that will continue through the rest of the year.

The first I-44 project began March 7, when MoDOT began work on the renovation of the eastbound I-44 bridge over the Burlington Northern Santa Fe Railroad at the St. Louis City limits. The bridge replacement will be between Murdoch Ave. and River Des Peres. The ramp from Shrewsbury to east I-44 will be closed and drivers will also have shifted lanes during construction.

Crews closed two westbound lanes on I-44 between Jamieson and Shrewsbury. Those westbound lanes along I-44 in Shrewsbury are not expected to reopen until December 2018.

Crews closed the ramp from Shrewsbury to eastbound I-44 and one lane on eastbound I-44. They will then shift the remaining three lanes of traffic onto westbound I-44, for the remainder of the project.

"We encourage drivers that regularly use that section of I-44 to start looking at some of their other options now," MoDOT Assistant District Engineer Bill Schnell said. "For some, adjusting the time of their commute may be an option, or talking to their company about telecommuting options. Others may want to consider alternate routes to get around the construction."

The bridge work between Kingshighway and 39th Street includes rehabilitating the Union Pacific Railroad, Vandeventer and Tower Grove Bridges and replacing the Kingshighway, Thurman and 39th Street Bridges. One I-44 lane in both directions will be closed around the clock, and several ramps and cross streets will also be impacted.

MoDOT shifted westbound lanes onto the eastbound side of I-44 between Arsenal and Grand March 18. Eventually, one lane in each direction will be closed.

Crews will be working to replace several bridges on that stretch, including the Kingshighway bridge. The project will be completed in late 2019.

Below is a full list of 2018 roadway construction around the St. Louis region from MoDOT:

During this project, crews will also replace the pedestrian bridge over the interstate between the Edwards overpass and Kingshighway. One I-44 lane in both directions will be closed around the clock, and several ramps and cross streets will be impacted during the work.The project starts in early 2018 and will be completed in late 2019.

*I-44 bridge and pavement rehabilitation between Murdoch and the River Des Peres. (St. Louis County) This project replaces the eastbound bridge over the Burlington Northern Santa Fe Railroad. During construction, the ramp from Shrewsbury to eastbound I-44 will be closed in early spring 2018. Drivers will have shifted lanes – three eastbound and two westbound – during the project. The project has begun. The bridge project will be completed in late 2018, while final resurfacing will be complete in late spring 2019.

I-44 pavement repairs and resurfacing from east of Murdoch Avenue to Route 141. (St. Louis County) Work will be complete by the end of 2018.

*I-44 Meramec River Bridge replacement. (St. Louis County) This project replaces the eastbound and westbound I-44 bridges just west of I-270 over the Meramec.

I-44 bridge replacement between Route 100 and Route 50. (Franklin County) Replace the eastbound I-44 bridge over Route 50 in Franklin County. Crews will start work in March by building out the median and shifting traffic. Lanes will be narrowed but one lane will be open at all times. Most lane closures will be during off-peak hours. There will likely need to be a full closure at some point to set girders and demo the old bridge. In addition, crews will replace the bridge for St. Mary’s Road over I-44 this summer. Drivers can expect off-peak lane closures and some overnight closures for demolition and to set girders.
