Center Hill. Today, part of it is a Forest Road in Withlacoochee State Forest north of the Sumter Rest Area on I-75. A fourth one was part of the Orange Belt Railway, which ran from Trilby in Pasco County to Sylvan Lake in Seminole County. This runs along the south side of State Road 50 east of Tarrytown. Major roads Interstate 75 runs north and south across the western and northern part of the county, with interchanges at County Roads 476B & 673(Exit 309), SR 48 (Exit 314) CR 470(Exit 321), Florida's Turnpike(Exit 328), and SR 44(Exit 329). Florida's Turnpike runs north and south from Southeastern and Central Florida. Only two interchanges exist in the county; US 301(Exit 304) and at the northern terminus at I-75(unmarked Exit 309), in Wildwood.
