For some months, the bridge at the Blackwater River on Mo. Route 23, south of Concordia, in Johnson County, has had a steel plate in the center of its driving surface. On Monday, July 18, that bridge will close to traffic so it can be replaced.

According to Missouri Department of Transportation Area Engineer Rich Shipley, it will be closed for approximately 75 days, weather permitting, during the replacement.

"The big reason it is getting replaced is because it is beyond its service life. Its width is also not exactly what we would like it to be," he said in a phone interview.

At present, the bridge is approximately 24-feet wide. Once replaced, it will be around 28-feet wide.

Traffic traveling south on Route 23 heading to communities such as Knob Noster, Sedalia or Warrensburg will have to take alternate routes during construction. A signed state detour will be in place and will send traffic west on Route 50 at Knob Noster, north on Route 13, east on I-70 and south on Route 23 at Concordia.

MoDOT crews will also close Route DD just west of Shawnee Campground Road outside Whiteman Air Force Base, at Knob Noster, in Johnson County, Monday, July 18. MoDOT is replacing a culvert and expects the road will reopen in early August. Work is weather dependent. An estimated 5,000 motorists travel this route daily, according to a MoDOT release.

MoDOT is urging all motorists to be alert and use caution when driving through work zones. Follow the posted speed limits, and take turns merging every other car, like a zipper, where lanes are closed, a press release noted.
