The Embarcadero is the eastern waterfront and roadway of the Port of San Francisco, San Francisco, California, along San Francisco Bay. It was constructed on reclaimed land along a three mile long engineered seawall, from which piers extend into the bay. It derives its name from the Spanish verb embarcar, meaning "to embark"; embarcadero itself means "the place to embark." The Central Embarcadero Piers Historic District was added to the National Register of Historic Places on November 20, 2002. The Embarcadero right-of-way begins at the intersection of Second and King Streets near Oracle Park, and travels north, passing under the San Francisco–Oakland Bay Bridge. The Embarcadero continues north past the Ferry Building at Market Street, Pier 39, and Fisherman's Wharf, before ending at Pier 45. A section of The Embarcadero which ran between Folsom Street and Drumm Street was formerly known as East Street. For three decades, until it was torn down in 1991, the Embarcadero Freeway dominated the area. The subsequent redevelopment and restoration efforts have, according to the National Trust for Historic Preservation, "contributed to a remarkable urban waterfront renaissance", with the Embarcadero Historic District serving as a "major economic engine for the Bay Area". History San Francisco's shoreline historically ran south and inland from Clark's Point below Telegraph Hill to present-day Montgomery Street and eastward toward Rincon Point, enclosing an inlet named Yerba Buena Cove. As the city grew, the cove was filled. Over fifty years a large offshore seawall was built and the mudflats filled, creating what today is San Francisco's Financial District. The San Francisco Belt Railroad, a short line railroad for freight, ran along The Embarcadero; its former enginehouse has been preserved. The roadway follows the seawall, a boundary first established in the 1860s and not completed until the 1920s. During the early-20th century when the seaport was at its busiest and before the construction of the Bay Bridge, Pier 1, Pier 1½, Pier 3 and Pier 5 were dedicated chiefly to inland trade and transport. These connections facilitated the growth of communities in the Sacramento- and San Joaquin Valleys and fostered California's agricultural business. Today, these piers comprise the Central Embarcadero Piers Historic District. The Delta Queen docked at Pier 1½, ferrying people between San Francisco and Sacramento. There was once a pedestrian footbridge that connected Market Street directly with the Ferry building and a subterranean roadway to move cars below the plaza.
