The Missouri Department of Transportation is set to begin intersection improvements and install traffic signals and street lighting in Joplin starting August 5, with significant lane closures and delays expected. Concurrently, Florida Avenue will be closed for two days starting July 23 due to sewer work for a new building. Additionally, from July 21 to July 26, lanes on 7th Street (Route 66) will be closed overnight for manhole inspections as part of a future improvement project. Drivers are advised to seek alternate routes and exercise caution due to ongoing construction activities affecting various streets in Joplin. Meanwhile, traffic delays are also reported on Interstate 75 in Hillsborough County, Florida, due to construction reducing lanes. Overall, multiple roadwork projects across Joplin and nearby areas are likely to cause significant traffic disruptions.
