How to reach:
To reach tidal bench marks from Saipan International Airport, proceed 3.4 km (2.1 mi) north along an unnamed road. As the road terminates, turn left (west) onto Cross Island Road (Note: there are no road signs in Saipan). Turn right (north) on Middle Road (first large intersection with traffic light) and proceed for 8 km (5 mi). Turn left (west) immediately after the WESTPAC building (located on the west side of Middle Road). The unnamed road will bend to the south, turn right (west) just past the Port of Saipan Building (two story concrete building painted beige). Proceed through the parking toll booth and turn right toward the NNE side of the port facility. The bench marks were located on the Port of Saipan facility. The tide gauge was located where east parking lot meets with the east face of Delta Dock.
