of the Delaware Railroad near the town, which stopped the growth of the town and increased the isolation of Frederica from other towns. The Delaware Railroad was built well to the west of Frederica through Dover and Felton. The town later attempted to get a railroad connection by chartering a railroad line that would run from Dover to Milford via Frederica as well as pushing for a branch of the Delaware Railroad from Felton to Frederica; both efforts were unsuccessful. The last shipyard in Frederica closed around 1890, but other industries would become prominent in Frederica. By 1887, the town had three canneries, with other businesses such as fertilizer manufacturing, a hat factory, two brush factories, a cooper, a butcher, a hotel, a clothing house, and ten general stores. A steamship operated by the Frederica and Philadelphia Navigation Company linked Frederica with Philadelphia until the onset of the Great Depression. In the 1920s, improvements to U.S. Route 113 that included a causeway into Frederica cut the town off from the Delaware Bay. Improved roads in the 20th century would provide better connections with Harrington, Dover, and Wilmington, reducing the need for the steamship to Philadelphia. Maritime activity in Frederica declined, the port quieted down, and the canneries and many businesses in the town closed. U.S. Route 113 was rerouted to bypass Frederica to the east along what is now Delaware Route 1. Today, Frederica is a quiet town that has not experienced much change unlike many places in the United States. The Barratt Hall, Barratt's Chapel, Bonwell House, Frederica Historic District, and Mordington are listed on the National Register of Historic Places.
