Although the pier quickly became a popular destination for locals and tourists, its original purpose was for fishing. Local Ocean Beach fishermen needed a way to prevent their fishing lines and lures from getting tangled in the vast kelp and rock beds that lie near the surface of the water near the shores. With the construction of the OB Pier, anglers are able to fish in 25-30 feet of water, avoiding most of the shoreline kelp and enabling them to catch species of fish that live in deeper waters. The pier extends 1971 feet into the ocean and is the second longest pier on the west coast and purported to be the longest concrete pier in the world. Its unique T-shape at the end of the pier adds 360 feet to the south and 193 feet to the north. The OB Pier was not the first attempt at providing OB residents a place to fish. Prior to the completion of the pier, a bridge had been constructed in 1915 across the mouth of Mission Bay, which extended from the north end of Bacon Street to what is now the dunes of Mission Bay. This bridge, which was 1,500 feet long, was mainly built so residents could travel from Voltaire to Mission Beach. Soon after its construction, local fishermen thought they had finally found a place to fish. Though the bridge served its primary purpose as a means of transportation for local residents, it proved to be a poor solution for the town’s fishermen. When the bridge was taken down in 1951, San Diegans were promised a replacement for the tourists and fishermen who enjoyed it. After 15 years, the city finally came through on its promise and opened what is now the OB Pier at the foot of Niagara, a location proven better suited for tourists and anglers alike.
