of the county, intersects I-75 in Ridge Manor West and meets the Suncoast Parkway at the parkway's current end near World Woods Golf Course north of Brooksville. US 301 (Treiman Boulevard) is a north–south highway that crosses into the county briefly at its tapered eastern end, running parallel to I-75, and intersecting with SR 50 at Ridge Manor. Interstate 75 runs north and south across the eastern part of the county, with one exit (Exit 301) at its intersection with US 98/SR 50. Once a major connecting point with Tampa, I-75 has been made obsolete for western residents of the county by the Suncoast Parkway. Suncoast Parkway (SR 589) enters the county in the south slightly to the west of US 41, and ends in the far northern part of the county at US 98. (N.B. the Suncoast Parkway is considered incomplete; there are plans for it to extend through northern Hernando County and through adjacent Citrus County and head into Crystal River.) The Suncoast Parkway is a toll road that connects Hernando County with Hillsborough County, where it becomes the Veterans Expressway and heads directly into Tampa International Airport before reaching Interstate 275. SR 589 has four Hernando County exits: County Line Road (Exit 37), Spring Hill Drive (Exit 41), SR 50 (Exit 46), and US 98 (Future Exit 54). SR 50 (Cortez Boulevard) begins at US 19 in Weeki Wachee, runs through Brooksville, and exits into Sumter County at the eastern tip of the county. Along the way, it interchanges with the Suncoast Parkway, intersects with US 41 in Brooksville, runs concurrently with US 98, and intersects with I-75 in Ridge Manor West(Hernando County's only interchange with I-75) and US 301 in Ridge Manor. A significant, well-developed highway in the county, SR 50 originally extended from US 19 to the Gulf Coast at Bayport. This section was given back to the county and is currently CR 550. Currently, S.R. 50 is used as a beeline route from the county to Orlando in the east. SR 50 Alternate (Jefferson Street) is a spur of SR 50 that runs through downtown Brooksville, running concurrently with both US 41 and US 98 at points. Spring Hill Drive (CR 574) is a major county road running roughly parallel to both SR 50 and the border with Pasco County beginning by US 19, intersects the Suncoast Parkway, and ends at US 41. County
