After the Bluffton Parkway, which provides direct access to
Now in Beaufort County proper once again, the highway becomes more scenic, with panoramas of marshes and surrounding islands extending for miles. The divided highway ends again, as it approaches the Edgar C. Glenn Boat Ramp under the four-lane (with center-painted divider) bridge over the Chechesee River and enters Lemon Island.

History
Established around 1931 as a new primary routing from US 17 (today Levy Road S-27-34) to SC 33 (today SC 46). In 1939, it was extended north to where US 278 exists today. In 1940, it was extended north again to SC 368, near Coosawhatchie; and again by 1942 to US 17 in Coosawhatchie.[7] In 1949, SC 170 was extended west from Coosawhatchie to SC 128, near Gillisonville, a renumbering of SC 366.[8] In 1958, SC 170 was rerouted to US 21 in Beaufort, via the Broad River Bridge, replacing part of SC 169; its old alignment north through Coosawhatchie was renumbered to SC 462.[9][10][11] Around 1975, SC 170 was extended slightly south over an old alignment of US 17 as mainline US 17 was placed on a new bypass west of Limehouse.[12] In 1995, SC 170 was extended south into Georgia, replacing a section of mainline US 17.
