1887. One phase of construction was the building of a bridge over what is now Tunnel Street in Locust Valley. The masonry project began in October 1888 and the arch was finished on April 13, 1889. The entire bridge was completed by September. On June 24, 1889, the extension opened with a huge celebration in Oyster Bay. A ceremonial train of ten cars left Long Island City about 9:30 a.m. and was met at Locust Valley by ten young ladies who decorated the locomotive with flags and wreaths. Upon arrival at Oyster Bay, an organized procession commenced, which was viewed by 5,000 residents and visitors. On Tuesday, June 25, the extension opened for regular passenger service with eight round trips daily to and from Long Island City. The line ended at Locust Valley for two decades until a final extension added four miles (6.4 Kilometers) to Oyster Bay. One of the reasons for building to Oyster Bay was to create a connection to New England. A large pier, now owned by the Flowers Oyster Company, was built to facilitate the loading of passenger cars onto a ferry, specifically to the Danbury and Norwalk Railroad station and ferry pier in Wilson's Point section of Norwalk, Connecticut. Service lasted only a few years as overland service from New York to Boston, once thought impossible, commenced. In early 1892, a second track was built between Mineola and Albertson. 20th century to present The line was double-tracked to Roslyn, Glen Cove and Locust Valley in 1905, 1909 and 1911, respectively. The extension of the line's second track was done in anticipation of electrification. Until 1928, a direct connection to the West Hempstead Branch existed just east of Mineola station. This spur crossed the Main Line, then terminated at the end of a wye at what was often called the Garden City Branch. Until passenger service was abandoned along this branch, passengers would transfer between the two lines at Mineola Station itself. In November 1928, LIRR officials surveyed the branch to evaluate the feasibility of electrifying the line. The Glen Cove Chamber of Commerce petitioned the LIRR, advocating for electrification. In response, the Vice President of the LIRR, in December, stated that the LIRR had to deal with the completion of multiple grade crossing elimination projects before electrifying the Oyster Bay Branch, which was estimated to cost $3.28 million. By June 1934, the section of
