South Carolina Highway 70 (SC 70) is a 29.990-mile (48.264 km) primary state highway in the U.S. state of South Carolina. It connects the cities of Barnwell and Denmark with Orangeburg via U.S. Route 301 (US 301) and US 601.[4]

Route description

SC 70 is connected together with barnwell, Denmark, Orangeburg and Allen St And Main St is Connected together


It was established around 1938 as a new primary routing from SC 64 in Barnwell to SC 6 in Denmark. In 1940, SC 70 was extended in both directions: west in concurrency with SC 64 to the Salkehatchie River, and east on new primary routing to SC 332. In 1941 or 1942, SC 70 was extended southwest on new primary routing to SC 28, then in concurrency with it to Martin, where it went southeast as new routing to SC 631. This would be SC 70 longest length with it reaching over 42 miles (68 km) long.

In 1948, SC 70 was converted back to its original 1938 routing between Barnwell and Denmark; however a four-mile (6.4 km) section also existed between Martin and SC 37. All roads not in concurrency were reverted to secondary status.

Around 1952, the Martin to SC 37 piece of SC 70 was downgraded to secondary status, becoming Revolutionary Trail (S-3-47). Around 1958, SC 70 was re-extended east of Denmark to its current eastern terminus with US 301/US 601.
