State Road 20 (SR 20) is a east-to-west route across northern Florida and the Florida Panhandle in the United States. Route description Okaloosa County (Niceville and Bluewater Bay) SR 20 starts at SR 85 in Niceville as John Sims Parkway, which travels to Eglin AFB East Gate through Valparaiso as westbound SR 85 and southbound SR 397. SR 20 heads slightly southeast while SR 85 goes north towards Crestview. The road shortly after intersects the southern terminus of SR 285 as it passes by Niceville High School, reducing to four lanes from six lanes. SR 20 continues straight through Niceville before turning more southeast, crossing the C.G. Meigs Bridge over Rocky Bayou, exiting the Niceville city limits and entering Bluewater Bay. 3 miles later, the road intersects SR 293, providing access to Destin via the Mid-Bay Bridge before reducing to two lanes and entering Walton County. Walton County Briefly after crossing the county line, SR 20 continues southeast before turning east into Choctaw Beach, skirting along the Choctawhatchee Bay, as a two lane road. Upon leaving Choctaw Beach, the speed limit increases from to into Portland, intersecting Eglin Site C-6 before intersecting County Road 83A, a loop road, twice in Freeport. Shortly after the second intersection with CR 83A, the road intersects US 331 Business, which happens to be US 331's old alignment through Freeport. SR 20 shortly after intersects US 331, exiting the town shortly after. Throughout the rest of Walton County, SR 20 does not intersect many roads other than SR 81 in Bruce, continuing eastbound. Washington County SR 20 is very short through Washington County, only intersecting SR 79 in Ebro leading to Panama City Beach/Bonifay. The road runs for 5 miles before straddling the Washington/Bay county line for another 6 miles before veering southeast into Bay County. Bay County Only about a mile after completely going into Bay County, SR 20 intersects SR 77, passing by several lakes for a few miles before turning northeast. The road intersects Blue Springs Road, then turning directly east and running close to the Washington County line, but still entirely in Bay County. After the county line ends, the road heads straight east, intersecting US 231 between Fountain and Youngstown, and then enters Calhoun County. Calhoun County State Road 20 continues heading straight east before veering southeast, then curving northeast, to finally resume the straight eastward pattern. The road becomes
