Miami Dade Busway and South Dade Rail Trail run on the former right of way from Kendall to Florida City. With the reintroduction of passenger service on the FEC via Brightline in the 2010s, the southern half of the main line is once again being expanded to double track. Track from Miami to West Palm Beach was complete in late 2017. Work is currently underway to expand the line to double track from West Palm Beach to Titusville as part of Brightline's second phase. Many bridges are also being rebuilt along this segment as part of the project, despite the fact that many of the older bridges still have adequate width from the previous double track. Kissimmee Valley Line The Kissimmee Valley Line, also known as the Okeechobee Branch, ran from just south of New Smyrna Beach through the Kissimmee Valley roughly paralleling the main line. Branching off the Main Line at Edgewater, it headed southwest to Maytown, where it crossed the Enterprise Branch. From Maytown, it turned south and headed through largely rural agricultural land to Okeechobee, a small town on the north side of Lake Okeechobee. South of Holopaw, the line roughly parallels US 441. Construction began at Maytown on February 25, 1911, and was completed to Okeechobee in 1915. The line was extended north from Maytown to Edgewater (just south of New Smyrna Beach) in 1916 to have its own connection to the Main Line. By 1923, the branch was extended from Okeechobee southeast and around the eastern side of Lake Okeechobee to Belle Glade. The Interstate Commerce Commission had authorized the FEC to extend the line as far as Hialeah to connect with the South Florida network, but it was never built south of Belle Glade. The line was instead extended from Belle Glade west to South Bay and Lake Harbor on the south side of the lake at the Miami Canal in 1929. Here, it connected with the Atlantic Coast Line Railroad's Haines City Branch. In 1947, the Kissimmee Valley Line was abandoned from Maytown to Marcy since it ended up not generating the agricultural traffic it had hoped to. At the same time, the remaining line south of Marcy to Lake Harbor was connected to the Main Line at Fort Pierce and is now part of the Lake Harbor Branch.
