Local Highway, Route Construction Information from MoDOT

Today’s scheduled closure on Route B has been postponed. The closure is now scheduled for Tuesday, Jan. 15 from 9 a.m. to 2:30 p.m.


A section of Route B in St. Charles County will be closed later this week so crews can replace an underground pipe. Route B will be closed at Lakeview Drive from 9 a.m. to 2:30 p.m., Wednesday, Jan. 9. There will be barriers at Route C and Huster Road on either side of the closure and local traffic only will be allowed past those points, but no traffic will be allowed through the closure at Lakeview Drive. All work is weather permitting.


Crews continue to work to remove the crossovers that were closed as a part of the Route 61 Safety Improvement project. As a result, one lane on both northbound and southbound Route 61 between Route A and Route P will be closed from 9 a.m. to 3 p.m., Friday, Jan. 4. One lane will be closed in the same location from 8 p.m. to 5 a.m. all next week. All work is weather permitting and may be shifted due to inclement weather. For more information on the Route 61 Safety Improvement project, go to


Now that the new interchange at Route P and Peine Road has been fully opened for a few days, the crossovers at Grothe Road and the two Granville Drives will be closing. Crews will start tomorrow (Tuesday, Dec. 18) morning closing the northbound crossovers. They will then move to southbound Route 61 and close those overpasses. All three crossovers are expected to be closed by 10 a.m. For more information on the Route 61 Safety project go to


Later this week, the new westbound I-70 exit to Route K in St. Charles County will open to traffic. The new ramp will also allow drivers to access the north outer road (East Terra Lane). When the new ramp opens sometime before afternoon rush on Friday, Nov. 30, the current westbound I-70 exit to Route K will close. At the same time the new ramp from East Terra to westbound I-70 will open. Drivers on T.R. Hughes will once again have access to westbound I-70 via the new ramp on East Terra. The changes are part of the I-70 Traffic Flow Improvement project. For more information on the project go to


Starting today, the T.R. Hughes ramp to westbound I-70 will be closed. The ramp will be relocated as part of the I-70 improvement project going on between T.R. Hughes and Route K. The new, relocated ramp will reopen later this year. Drivers can detour around the ramp closure by either taking the I-70 North Outer Road (East Terra) to Route K or taking Mexico to Route K. Please allow extra time while using these detour routes as the extra traffic could cause delays. For more information on the I-70 Improvement Project being done in conjunction with the City of O’Fallon, please visit the project website at


MoDOT is conducting roadwork affecting the interchange at I-70 and Route K, and the outer roads between T.R. Hughes Boulevard and Woodlawn Avenue through late 2018. For closures, detours and additional project information, visit the City of O'Fallon's website and the website below.
