How can an alleyway twenty cubits wide be corrected?

Synopsis

An alleyway twenty cubits wide can be divided by a four-cubit-wide post placed in the middle, creating two separate alleyways on either side. Alternatively, posts set back from the walls in specific configurations can reduce the width. Each resulting section must meet all mavoi requirements.
