What happens when a lechi or korah is placed in the middle of an alleyway rather than at its entrance?

Synopsis

Placing a lechi in the middle of a mavoi divides it into inner and outer sections. When both sections also make their own correctives, they can each have a separate eruv. If a tzurat hapetach or two-post arrangement is used in the middle, division is more complete.
