If it becomes necessary or wise to exit the river, at this point there appears to be a double-track (fire lane?) to the left (south/west) parlleling the river. You should be able to walk this (from this point, or any point further along the run) all the way to our listed take-out.
In that regard ... it may be wise (before deciding to put on and run this river) to scout as much of this stretch as possible! The double-track will be too far from the road to see the river, but if you walk about 1 mile down that road til it veers sharply west, head due east (or Northeast) about 500-600' (dropping 30-40 feet) to reach the river, and walk downstream back to your vehicle(s).
