They are sometimes on either side of the bridge. On one end (Millwood and Overlea) they park their cruiser up in the park so it looks like an extension of the bridge railing. Then they hide near the railing with the radar gun pointed down the bridge to the lights at Pape Ave. and Millwood Drive.
On the other side, they park the cruiser over on the sidewalk and sit in the little island that’s about right in the middle of the road and point the radar gun down the bridge to the lights at Millwood Dr. and Overlea Blvd.
They are not there all the time but I usually see them in the afternoons. Its a good idea to not speed there just in case.
