South Carolina Highway 277 (SC 277) is a state highway in the U.S. state of South Carolina that runs 8.1 miles (13.0 km) from I-77 (Exit 18) between Killian and Dentsville in Richland County to US 76 (Elmwood Avenue) in downtown Columbia. For most of its length, it is a controlled access freeway (motorway) conforming to interstate standards. The highway serves as a spur into Columbia from its northeastern suburbs and from intercity traffic traveling from I-77 and I-20. The freeway portion of SC 277 is called the Northeastern Freeway or I. DeQuincey Newman Freeway while the 0.7 (1.1 km) miles of surface street is part of Bull Street.

The SC 277 designation was carried from I-77/Farrow Road to the Sunset Drive (SC 16) interchange, with all traffic using the Bull St. ramps to enter/exit the freeway. Southbound traffic has followed the surface street/boulevard (originally designated by SC DOT as "Road P-4001") to the U.S. 76/Bus. Spur I-126 (Elmwood Avenue) intersection to the present day. SC DOT replaced P-4001 with an official SC 277 designation southward on the approximately 1 mile of Bull Street from the freeway end to Elmwood Ave. in 1991. Though an additional mile or so of right-of-way had already been acquired by SC DOT from Bull St. to just past River Drive (U.S. 176), the project was placed on indefinite hold in 1979 due to funding and neighborhood opposition issues. In 1982, SC DOT canceled the project, finally returning (actually, "leasing" for $1) the unused right-of-way back to the city of Columbia in 2001. Interstate-standard mileposts were placed in 2005, though at no time was the route considered for incorporation into the existing Interstate Highway system as an "Interstate 277". SC 277 was also applied to another route from 1941-42 until 1948 between SC 215 and the current US 321 in northern Richland County. It is now S-40-38 (Camp Ground Road).
