Michigan City Shoal Lighted Buoy 2 has a QR characteristic and should be used as the primary starboard hand mark when entering the harbor channel. In an effort to prevent confusion, Michigan City West Pierhead Light (LLNR 19565) has been temporarily disestablished until dredging can be completed. Mariners are urged to use caution when transiting the area and are discouraged from transiting inside the temporary buoys and west pierhead. \n\n","COORDINATES_JSON":"{\"type\":\"Polygon\",\"coordinates\":[[[-86.91244,41.73056],[-86.91386,41.72986],[-86.91334,41.72845],[-86.91278,41.72805],[-86.91152,41.72746],[-86.91115,41.728],[-86.90995,41.72749],[-86.90952,41.72659],[-86.90991,41.7265],[-86.90903,41.72449],[-86.90832,41.7247],[-86.90995,41.72819],[-86.91197,41.72906],[-86.91244,41.73056]]]}","COORDINATES_TYPE":"Polygon","DECIMAL_LONGITUDE":null,"DECIMAL_LATITUDE":null}}]}
