Lime Point was automated by the United States Coast Guard in 1961, and the three-story dwelling and other buildings were torn down, leaving only the fog signal building, which remains. Lime Point Lighthouse continued to operate after the completion of the Golden Gate Bridge since it remained an effective position for a light and fog horn, even though Fort Point Light, at the South end of the bridge was decommissioned. A subsequent investigation into the incident identified high winds, which rendered the foghorn signal ineffective, and currents in the strait as causes of the accident.

The Lime Point Light Station sustained $7,500 in damage (most notably the facility's toilet was completely destroyed) in the accident, while damage to the freighter was $60,000.

In 1902, the coal-powered steam horn was modified to use crude oil to reduce operating costs and smoke pollution. In 1900, a lens lantern was hung on the south-east corner of the fog signal building, at a height of 20 feet (6.1 m) above the water. The keeper's building was later upgraded to include a third floor. During operation, the facility included the fog signal building, a coal shed, water tank and a two-story keeper's quarters. It was eventually fitted with coal powered 12-inch (300 mm) steam whistles. The brick structure for the Lime Point Lighthouse was built in 1883 as a fog-bell signaling station. It is built on a 100-foot (30 m) long rock spur named Lime Point. The lighthouse sits at the base of a steep cliff, very near the North anchorage of the Golden Gate Bridge.
