County Road 512 (CR 512), or Sebastian Boulevard east of Interstate 95 (I-95), is a major eastâÂÂwest county road in northern Indian River County, Florida. The highway serves as one of two current I-95 exits in the county. CR 512 connects Indian River CountyâÂÂs largest city, Sebastian, to I-95. The highway acts as main artery in Fellsmere, where it passes through its downtown as Pennsylvania Avenue.
CR 512 serves a vital role for the connectivity of the city of Fellsmere. According to TCPalm, during hurricane evacuations the road is especially important because it is one of two roads to enter and leave the city. During Hurricane Milton in October 2024, a culvert collapsed, causing CR 512 to be impassable until January 2025.
In 2026, a 2.5-mile portion of the highway between I-95 and CR 510 will be redesignated State Road 512 (SR 512) when the roadway is transferred to the Florida Department of Transportation (FDOT).
CR 512 starts at SR 60 near Blue Cypress Lake west of Vero Beach. It continues northward towards Fellsmere before turning northeast towards downtown Fellsmere. CR 512 then shifts east at CR 507, before its interchange with I-95. Finally, at CR 510, CR 512 shifts northeast intersecting CR 505 in Sebastian. Near Delaware avenue in Sebastian, CR 512 splits into two one-way branches before intersecting with US 1.
