Hernando County Road 578 - County Line Road

Home » Guides » Florida » Hernando County Road 578 - County Line Road

The westernmost of three County Road 578 segments, Hernando County Road 578 bee lines east 10.82 miles from U.S. 19 (Commercial Way) to U.S. 41 (Broad Street) along the Pasco / Hernando County line. Most of the route remains a rural-type two lane roadway. Suburban development from Spring Hill lines several stretches of the road to the north however, and portions of County Line Road were expanded to urban arterial standards as a result.

A second segment of Hernando County 578 zigzagged east from U.S. 41 at Masaryktown along a combination of Wilson Boulevard, Benes Road, Benes Roush Road and Philips Roads to CR 576 (Ayers Road). The eastern portion of this alignment is unpaved.

The other sections of County Road 578 serve Dade City. The eastern leg follows Lock Street between CR 41 (Blanton Road) and U.S. 98/401. The western portion lines St. Joe Road west from CR 41 (21st Street) to CR 581 (Bellamy Brothers Boulevard) near Darby.
