County roads in Florida County roads in Brevard County

Brevard County, Florida (located in the East of Central Florida), operates a system of county roads that serve all portions of the county. The Brevard County Public Works Department, Road and Bridge Division, is responsible for maintaining all of the Brevard County roads. Most of the county roads are city streets and rural roads.

The numbers and routes of all Florida highways are assigned by the Florida Department of Transportation (FDOT), while county road numbers are assigned by the counties, with guidance from FDOT. North-south routes are generally assigned odd numbers, while east-west routes are generally assigned even numbers.

CR 3 (former SR 3) begins at an intersection with SR 513 in Indian Harbor Beach and ends at an intersection with SR 520 in Merritt Island, Florida.

CR 5A (former SR 5A) is a 1-mile (1.6 km) long county road located entirely in the Brevard County Game Refuge, in the unincorporated community of Scottsmoor. The highway begins at exit 231 from I-95, a diamond interchange, and travels northeast through woodlands until it terminates at an intersection with US 1. The highway is the northern most county route in Brevard County, located only 1 mi (1.6 km) from the Volusia county line.
