Road work placeholder

Work continues at the intersection of Mitchell Avenue and South Belt Highway. Evening signal work will affect motorists starting Monday, Sept. 12, at 6 p.m.

Missouri Department of Transportation will be upgrading the left-turn signals at the intersection to flashing yellow arrows, along with routine maintenance.

The work will require crews to close the turn lanes in order to change out the signals heads, signs and vehicle detection system. During different portions of the project, the signals will be inoperable and stop signs will be in place.

In the news release, MoDOT wants drivers to remember that whenever a signal is dark or in flash mode, the intersection should be treated as a four-way stop.

Crews hope to have the work completed by 7 a.m. Tuesday, Sept. 13. But after the signals are operational, workers will be present at the intersection performing maintenance work. Motorists should use extra caution and may encounter delays throughout the night. All work is weather permitting and could be rescheduled.
