Indiana Department of Transportation officials closed State Road 156 this afternoon (JULY 30) after an embankment slide adjacent to the Ohio River made the roadway unsafe at a location 2.95 miles west of the S.R. 56-S.R. 156 intersection in northeast Switzerland County. S.R. 156’s eastbound lane dropped significantly due to recent rains and flooding.
A signed detour is being placed that routes motorists around the closure via S.R. 250 and S.R. 56.
INDOT is exploring the possibility of reopening S.R. 156 to alternating single-lane traffic controlled by temporary signals on either side of the slide—but placement of signal poles in such close proximity to the slide and the river may be problematic. Meanwhile, a full closure will remain in effect.
This slide site is approximately one mile from the S.R. 156 Grants Creek bridge which reopened in mid-June after an extended closure for repairs. The site has been monitored by INDOT on a regular basis for embankment erosion.
