Police Chief Matt Mansell said area residents should not be concerned when they begin to hear an unusual number of helicopters overhead in the coming weeks.

Mansell notified community leaders and The Missourian that Ameren Missouri would use helicopters in a month-long inspection of high wires.

Ameren Missouri sent notices to municipalities in the inspection area that residents might begin to hear the helicopters this week.

The utility company will be performing maintenance and reliability upgrades to 26 miles of transmission wires in communities from west St. Louis County to the Metro East.

“The work is unique, in that we are utilizing a helicopter to perform high wire work, minimizing our footprint on the ground,” an Ameren spokesman said.

The helicopter allows Ameren Missouri to update aging transmission lines in a significantly shorter time frame – weeks, rather than months.

The helicopter and crew may draw attention from area residents and businesses.

“The public should be aware that all necessary safety precautions and permits are in place,” the Ameren spokesman said.

The helicopter work will be ongoing through May 12, weather permitting, and may include weekends.

The upgrades will enhance the energy grid and provide safe and dependable energy for communities throughout our region.
