Hi Reggie,

You can do this with a simple TextSpanner:

\version "2.19.82"

onStaffExtender = {
  \override TextSpanner.style = #'line
  \override TextSpanner.thickness = #6
  \override TextSpanner.to-barline = ##t
  \override TextSpanner.outside-staff-priority = ##f
  \override TextSpanner.Y-offset = #0
  \override TextSpanner.bound-details.left.padding = #0
  \override TextSpanner.bound-details.right.padding = #0
  \override TextSpanner.bound-details.right-broken.text =
  \markup \fontsize #5 \arrow-head #X #RIGHT ##t
  \override TextSpanner.bound-details.right.text =
  \markup \fontsize #5 \arrow-head #X #RIGHT ##t
}

\score {
  <<
    \new Staff \repeat unfold 80 c'4
    \new Staff {
      c'1
      \stopStaff
      \once \onStaffExtender
      <>\startTextSpan
      s1*18
      \startStaff
      <>\stopTextSpan
      c'1
    }
  >>
}
