MoDOT 141 Updates
Updates July 24, 2017
As part of the next steps in the project, crews will be putting the deck on the new bridge over Route 141 and on the flyover ramp between southbound Route 141 and eastbound I-44. To do that, though, they need to first place girders. Because these are heavy and we must swing them over the interstate and Route 141, we cannot have vehicles traveling underneath them as we move them into place.
We will start on Wednesday, July 26 at 7 p.m. placing the girders over Route 141. Drivers can expect the following:
- At 7 p.m., crews close one northbound and southbound lane on Route 141.
- At 8 p.m., crews will close a second northbound and southbound lane on Route 141.
- At 8:30 p.m., crews will start flashing the signals at the North and South Highway Drive –making them four way stops.
- At 9 p.m., crews will start setting the girders. When they swing the girders over the roadway, they will close northbound and southbound Route 141 for up to 15 minutes.
- By 5 a.m. Thursday, July 27, crews will have signals cycling again on North and South Highway Drive and have all lanes open.
We will set the girders for the portion of the new flyover ramp over Route 141 on Thursday night, July 27. Drivers can expect the following:
- At 7 p.m., crews will close one northbound and southbound lane on Route 141
- At 8 p.m., crews will close a second northbound and southbound lane on Route 141 and will put the North Highway Drive signal on flash. Crews will also remove the northbound Route 141 signal at South Highway Drive and place stop signs with lighting at the intersection.
- At 10 p.m., crews will completely close northbound Route 141 at South Highway Drive. The detour will be to take South Highway Drive to Maritz to North Highway Drive to northbound Route 141.
- At 10 pm., crews will start setting girders. When they swing girders over the roadway, they will close southbound Route 141 for up to 15 minutes.
- By 5 a.m. Friday, July 28, crews will have replaced the northbound Route 141 signal, started all signals cycling again on North and South Highway Drive and have all lanes open.
Finally, we will be setting the girders for the portion of the flyover ramp over I-44 on Friday night, July 28. Here’s what drivers can expect that night:
- At 8 p.m., crews will close one lane on eastbound and westbound I-44.
- At 10 p.m., crews will close a second lane on eastbound and westbound I-44.
- After 11 p.m., depending on traffic levels, crews will place the North Highway Drive and South Highway Drive signals on flash, making them a four-way stop.
- After 11 p.m., depending on traffic levels, crews will set the girders over the interstate which will require a full closure of up to 15 minutes in each direction. When the interstate is closed, traffic will be routed down the ramp and back onto the interstate.
- By 6 a.m., Saturday, July 29, crews will have started all the signals cycling again and will have all lanes open.

MoDOT to close South Highway Drive, EB I-44 ramp at Route 141 overnight July 21
- LOUIS – Drivers should consider alternate routes when crews close access between Route 141 and eastbound I-44 overnight Friday, July 21.
Work will start at 7 p.m. when crews will close:
- All but one lane on the ramp from EB I-44 to Route 141, and
- All but one lane on South Highway Drive between Route 141 and Smizer Station Road.
Crews will fully close South Highway Drive before Smizer Station at 9 p.m. and will fully close the EB I-44 ramp at 10 p.m.
During the closures, crews will be making pavement repairs to prepare the ramp and outer road for resurfacing later this summer.
To detour around the South Highway Drive closure, drivers can take Valley Drive to Smizer Station Road to get to South Highway Drive and follow it to Bowles to get onto eastbound I-44.
To detour around the ramp closure, drivers can continue east, exit at Bowles and loop back around to westbound I-44 to get to Route 141 to detour around the closure.
The ramp and South Highway Drive should reopen by 7 a.m. Saturday, July 22.

Update May 30, 2017
MoDOT prepares to open ThrU Turns at Vance, Marshall
In a little more than a week, MoDOT will open a new type of left turn along Route 141 in Valley Park.
Called a ThrU Turn, drivers do not make a direct left turn. Instead, they drive through the intersection to a signalized U-turn location, make a U-turn, backtrack along the highway and make a right turn onto the side street.
MoDOT is set to open two ThrU Turns in Valley Park, one at Route 141 and Vance Road, and one at Route 141 and Marshall Road on June 8. The new turns are the first of their kind in Missouri. The new turns should reduce time waiting at a signal during peak traffic periods and improve the flow of traffic.
Drivers wanting to turn left at Forest Avenue and Meramec Station Road will also use the new ThrU Turns. According to Federal Highway studies, this type of intersection reduces crashes by nearly 40 percent, making it much safer
“Traffic is very congested in Valley Park, especially during rush periods. Part of that is due to traffic turning left from Route 141 onto Vance Road. With the railroad bridge between Vance and Marshall, we cannot lengthen the left turn lanes onto Vance or Marshall. During morning and evening rush, those drivers quickly fill up the available left turn space and then block the lanes for drivers who want to go through. These new turns should help reduce that backup,” said Karen Yeomans, MoDOT St. Louis area engineer for the southwest portion of St. Louis County.
Overall construction continues through summer 2018. Yeomans cautions that on-going construction and drivers learning to use the new ThrU Turns will mean that the overall benefits for the turns may not be observed until next summer.
“As drivers are heading into this for the first few times, we encourage them to slow down and pay attention to the signs that will guide them through the new intersections We will continue to monitor these new turns through the project, but ask drivers to be patient through the remaining construction, ” Yeomans said.
Information on reaching Vance Road, Forest Avenue, Marshall Road and Meramec Station Road, as well as a video on driving through the ThrU Turns is available at www.tinyurl.com/ThrUTurns
Photos & design plans: MoDOT Route 141 and I-44 Design-Build Project Update
Update April 25, 2017:
Work continues along much of the Route 141 Design-Build project in Valley Park. Crews continue to work on the new flyover ramp from southbound Route 141 to I-44 and on the through turns north of Vance Road and south of Marshall Road.
The biggest immediate impact to traffic on the project will be the opening of the through turns at Vance Road and Marshall Road. We are planning to open those two through turns in early June after school is out – this will give drivers the opportunity to get used to the new turns while traffic levels are lower in the summer.
As we move toward opening the through turns, you can expect to see crews finishing up on the curbs, gutters and medians around Vance, Forest, Meramec Station Road and Marshall Road. You may see lane closures during non-peak traffic periods, especially near the roadway median. In roughly the middle of May, we will be closing the left turn from northbound Route 141 to Meramec Station Road. Drivers will need to continue northbound on Route 141 to Helfrich Road, loop around and head back to Meramec Station Road. This short closure means that we will be able to open up both the through turn north of Vance and south of Marshall Road at the same time. We will have some work after the turns open, but everything should be completed on the through turns by the end of August.
At the Route 141 and I-44 interchange, crews are working on retaining walls and the foundation for the flyover ramp.
Near the end of May, we will be opening the new connection between North Highway Drive and Route 141. As a part of the move, we will need to temporarily move two lanes of traffic turning onto southbound Route 141 to the new North Highway Drive connection. This will remain in effect until we complete the loop ramp connection to southbound Route 141 in 2018. Drivers will have a shared lane to turn either right or left, a left turn lane and a right turn lane. Please see the image below.
The new entrance ramp to westbound I-44 should also open this summer.
In late summer, we are planning some short term closures overnight, as we move girders across the roadway and put them into place. We’ll have several nights where we need to have partial closures on Route 141 overnight, and we’ll have one night where we’ll have to close all eastbound lanes on I-44 and send traffic down the exit ramp and back up the entrance ramp while we set girders for the flyover ramp. We’ll share that information as we get closer and have determined more specifics.
Earlier this month, we got some aerial shots of the project. You can view the photos here: https://www.flickr.com/photos/modot_stl_photos/albums/72157680732645270.
Update February 22, 2017: MoDOT to close western outer road connection to Route 141 next week
Drivers who use the I-44 north outer road in Valley Park will need to allow a little extra time to get around starting next week.
The Missouri Department of Transportation and its contractor, Pace Construction, will close the western ramp connecting southbound Route 141 and the north outer road before morning rush on Monday, February 27.
This closure is part of on-going work to update and rebuild the connections between Route 141, I-44 and the north outer road as a part of the Route 141 Design Build project in Valley Park. The connection will remain closed until mid-summer 2017.
To detour around the closure, take Route 141 south, turn left onto South Highway Drive and bear to the right. Take South Highway Drive to the Maritz overpass, turn left and then turn left onto North Highway Drive. Take North Highway Drive to the roundabout and access the north outer road. Details on the detour are available here: http://www.modot.org/stlouis/major_projects/documents/2017NORdetour.pdf
Update February 14, 2017: Thru-turns will open north of Vance and south of Marshall Road in June this year.
Update February 14, 2017: MoDOT to relocate commuter lot at I-44, Route 141 late this week:
Construction is continuing well on the design-build project. Work is well underway on the flyover ramp and the thru turns near Vance and Marshall. We’ll share more information on those thru-turns later this spring.
Of more immediate importance: On February 17, MoDOT will open the new Park and Ride lot on the east side of the Route 141 project. The following Monday (February 20) the department will permanently close the existing Park and Ride lot on the west side of Route 141. This will let crews continue making improvements to the north outer road system as a part of the Route 141 Design Build project. Drivers who have vehicles parked long-term at the Park and Ride lot should move them by February 17.
During the on-going construction, drivers will need to use detours to get to the new Park and Ride lot.
To get to the Park and Ride lot from:
- Westbound I-44: Exit at 141, take North Highway Drive to the roundabout and take the leg for the north outer road. The Park and Ride lot will be on the left.
- Eastbound I-44: Exit at Route 141. Cross over Route 141 to South Highway Drive. Turn left at Maritz and follow North Highway Drive to the roundabout. Take the leg for the north outer road. The Park and Ride lot will be on the left.
- Southbound 141: Until March – take the ramp to the north outer road, turn right and follow the outer road to the Park and Ride lot on the right. After crews close the ramp in March, southbound drivers will need to turn left toward eastbound I-44 and bear to the right to take South Highway Drive. Turn left at Maritz and follow North Highway Drive to the roundabout. Take the leg for the north outer road. The Park and Ride lot will be on the left.
- Northbound 141: before I-44, turn right onto the ramp for EB I-44 and bear to the right to take South Highway Drive. Turn left at Maritz and follow North Highway Drive to the roundabout. Take the leg for the north outer road. The Park and Ride lot will be on the left.
To get from the Park and Ride lot:
- To WB I-44: Turn right out of the Park and Ride lot and take the roundabout. Exit on the leg for the North Highway Drive. Follow it to Route 141 and cross Route 141 to the westbound interstate ramp.
- To EB I-44: Turn right out of the Park and Ride lot and take the roundabout. Exit on the leg for North Highway Drive. Follow it to Route 141, turn south and get in the left lanes for the eastbound interstate ramp.
- To northbound or southbound 141: Turn right out of the Park and Ride lot and take the roundabout. Exit on the leg for North Highway Drive. Follow it to Route 141 and turn north or south.
