Midway point?

The answer to this crossword question is likely “turnstile.” A turnstile is a type of gate that is commonly found at the midway point of a fence or barrier, often at entrances or exits to sporting events or amusement parks. Turnstiles typically consist of a series of rotating arms or bars that allow one person to pass through at a time, ensuring that only one person enters or exits the area at a time. Therefore, the “midway point” of a fence or barrier can be referred to as a “gate” when it is a turnstile.
