Ohio 666 covers 275 miles worth of ground. The westernmost 80 miles complements I-70. The next 93 miles runs around Columbus, totally bypassing the city. Then, there's a 12 mile break in the freeway, where 666 runs as a surface street. After that portion, it goes to freeway for the last 90 miles in Ohio. NOTES: All portions of Multi State 666 that already exist (whether it be a freeway or a surface street portion) have a deeper green background. All control cities and features that are intentional have a red background. RUNDOWN OF INTENTIONALS: Already existing OH-666
