Electric Ameren has a sub transmission electric power line which runs along the north side of US 52.

At station 443+55 they have a pole which conflicts with a proposed field entrance. They also have a pole located at 440+54 and 39.52’ RT that is close to the proposed NW corner of the new wingwall. They plan to relocate these two power poles to avoid the wingwall and entrance.

The cable goes aerial over the box culvert located near station 440+80 (they have two poles here).

At CR 3 their facilities go north and south. It then extends along the south ROW heading west. Their drawing ends so we do not know how far it extends in that direction.

It appears that the small pole near the box culvert on the north side of US 52 will be in conflict.
