Abstract:This project measured and assessed the surface stability of the portion of LA Highway 70 that is
potentially vulnerable to the Assumption Parish sinkhole. Using Global Positioning Systems (GPS)
enhanced by a real-time network (RTN) of continuously operating reference stations (CORS), the
Center for GeoInformatics (C4G) at Louisiana State University (LSU) has collected the horizontal and
vertical positions for control points located along the Highway 70 corridor between Bayou Corne (in
the west) and Bayou Choupique (in the east). Measurements were collected between September 2012
and June 2013. Data has been processed and made available to LA Dept. of Transportation &
Development (DOTD) via an Internet FTP site maintained by C4G. During the report’s measurement
period, no movement attributable to the sinkhole has been detected on Highway 70. The GPS
measurements did exhibit variability typically associated with random and systematic error. In order to
capture more accurate, precise, and consistent positions, a permanent monitoring solution is
recommended.
