Major intersections Related routes State Road 50A State Road 50A (SR 50A) is a former segment of SR 50 that runs primarily along West and East Jefferson Street, entirely in the city of Brooksville in the State of Florida. Like its parent route, it is signed east–west. The road begins at the intersection of SR 50 (Cortez Boulevard, including the realigned section) and CR 485 (Cobb Road). The realigned section of SR 50 serves as Truck Route 50 as well as part of Truck US 98, while CR 485 also serves as Truck US 98. At Ponce de Leon Boulevard (US 98/SR 700), it becomes concurrent with US 98, until its eastern terminus with SR 50 and Jasmine Drive. Shortly after this new concurrence, it makes a right along North Mildred Avenue, for eastbound traffic only, and both merge with US 41. Between North Mildred Avenue and May Avenue, eastbound SR 50A, US 41, and US 98 are concurrent along Broad Street, while westbound SR 50A, US 41, and US 98 are concurrent along East Jefferson Avenue, then West Jefferson Avenue. US 41 reunites with Broad Street at North Mildred Avenue. This one-way configuration for Broad Street and Jefferson Street has been in effect since November 1993, according to the Florida Department of Transportation. While both segments go up and down steep hills in the heart of the city, the Broad Street (eastbound) section runs over an old railroad bridge built in 1936. Turning south along East Jefferson Street near Roger's Christmas House, SR 50A & US 98 go down an easier hill where it curves to the left before the intersection with Martin Luther King Jr. Boulevard (formerly Summit Street/CR 581A), then zips past the northern terminus of CR 581 (Emerson Road), finally reuniting with SR 50, which US 98 becomes concurrent with until breaking away in Ridge Manor more than east. County Road 550 County Road 550 is a former segment and coastal spur of SR 50. It runs from the Gulf of Mexico in Bayport to US 19 in Weeki Wachee, where it becomes SR 50. Like its parent route, it is signed east–west,
