Interstate 16 (I-16), also known as Jim Gillis Historic Savannah Parkway is an east–west Interstate Highway located entirely within the U.S. state of Georgia. It carries the hidden designation of State Route 404 (SR 404) for its entire length. I-16 travels from downtown Macon, at an interchange with I-75 to downtown Savannah at Montgomery Street (Exit 167B). I-16's unsigned designation of SR 404 has a spur that is signed in Savannah.

The freeway begins at an interchange with I-75, just northwest of downtown Macon, in Bibb County. The Interstate proceeds southeast, traveling just east of the downtown area. It crosses over the Ocmulgee River and then has an interchange with US 23/US 129/SR 49 (Spring Street/North Avenue). It then has a partial interchange with SR 22 (2nd Street) that is only accessible from the westbound lanes. Almost immediately is an interchange with US 80/SR 87 (Martin Luther King Jr. Boulevard/Coliseum Drive). Within the eastern part of this interchange, the highway travels under a railroad bridge that carries railroad tracks of Norfolk Southern Railway. In the east-central part of Macon, I-16 travels through Ocmulgee National Monument but without direct access. Visitors need to first exit at the US 80/SR 87 exit. On the southern edge of the national monument, it crosses over Walnut Creek. It then travels on a bridge over some railroad tracks of CSX and Boggy Branch. After leaving Macon, I-16 curves to the south-southeast and has an interchange with US 23/US 129 Alt./SR 87 (Ocmulgee East Boulevard). In the interchange, the highway crosses over Swift Creek. It crosses over Stone Creek before entering Twiggs County.
