the east. Portions of this road have been closed to the public, as the old road runs past Mercury Marine's former Lake X landing strip. The rest of the alignment is on private property owned mostly by Deseret Ranch. At Holopaw, around the middle of the old alignment, U.S. Route 441 and State Road 15 split off to the south, leaving only US 192 and SR 500 beyond to Melbourne. West of Deer Park, the old road crosses to the south side of the new road. Several miles later, at Deer Park, County Road 419 begins to the north; the road to the south is unnumbered and ends at old US 192. From there, the old alignment heads straight east back to the current road, passing the Kempfer Sawmill and the former Union Cypress Railroad. Soon after the old and new alignments join, US 192 crosses into Brevard County on the original Kissimmee-Melbourne Highway, roughly paralleling the old Union Cypress Railroad. As it approaches Melbourne on New Haven Avenue, it crosses Interstate 95 (State Road 9), intersects County Road 511 (north only), crosses County Road 509, and intersects State Road 507. Soon after SR 507, US 192 cuts northeast to Strawbridge Avenue, which runs one block north of New Haven Avenue, providing a bypass of the Historic Downtown Melbourne. After crossing U.S. Route 1 (State Road 5) at the site of the historic 1900 Building, Strawbridge Avenue and New Haven Avenue merge at the west end of the Melbourne Causeway across the Indian River. New Haven Avenue is still maintained by the state east of US 1, and is considered a section of SR 500. East of the Indian River, US 192 enters Indialantic on Fifth Avenue, where it spends four blocks before ending at State Road A1A, one short block from the Atlantic Ocean. History Florida's State Road system was defined by law in 1923. Included in that system was State Road 24, running along the existing Kissimmee-Melbourne Highway from State Road 2 in Kissimmee to State Road 4 in Melbourne. This road had been built in 1918 through the land of George W. Hopkins. In the mid-1920s, SR 24 became part of the Dixie Highway, connecting the western route in Kissimmee with the eastern route in Melbourne. The United States Numbered Highways were assigned in late 1926, including U.S. Route 192, running from U.S. Route 92 in Kissimmee
