State Route 10 Loop (SR 10 Loop, also known as Loop 10, Paul Broun, Sr. Parkway, or the Athens Perimeter) is a state highway in the form of a beltway around downtown Athens in the U.S. state of Georgia built to freeway standards. Much of SR 10 Loop is concurrent with other highways (including U.S. Route 29 (US 29), US 78, US 129, US 441, SR 8, and SR 15). It also carries the unsigned SR 422. The only numbered routes to travel through downtown Athens are US 78 Bus., SR 10, and SR 15 Alt. Inner/outer directions are used to sign the loop. Between exits 4 and 8, there is an eight-route concurrency, consisting of US 29, US 78, US 129, US 441, SR 8, SR 10 Loop, SR 15, and the unsigned SR 422. This concurrency contains the most highways in a single United States concurrency, tied with a section of the I-465 beltway circling Indianapolis, Indiana. Route description SR 10 Loop begins at an interchange with US 29, US 78, SR 8 and SR 316 to the south, and Epps Bridge Parkway to the north in Oconee County south of Athens. It heads east as a four-lane freeway, concurrent with US 29, US 78, and SR 8, and crosses McNutt Creek to enter Clarke County and Athens as it meets a partial cloverleaf interchange with US 129, US 441 and SR 15, which includes a connection to Timothy Road to the north. Those three routes join SR 10 Loop as it continues east and crosses the Middle Oconee River. The freeway then curves to the northeast and intersects Milledge Avenue, where SR 15 Alternate begins, heading north from the interchange. After this intersection, SR 10 Loop crosses a Georgia shortline railroad and turns to the northeast, where it meets College Station Road at a diamond interchange. At this point the highway right-of-way abuts the University of Georgia campus; immediately north of the College Station Road interchange is an on-ramp to a campus parking lot that is normally closed, but is used on home football game days to allow departing spectators access onto inner 10 Loop directly from campus. Northeast of here, the highway crosses the North Oconee River and meets a folded diamond interchange with SR 10, which is Oconee Street west of the interchange and Lexington Road east of it. At this interchange, US 78 splits
