Interstate 270 is a complete beltway around Columbus, Ohio. The highway serves the suburbs of Dublin, Grove City, Hilliard and Gahanna among others. Port Columbus International Airport (CMH) is also situated nearby the Interstate 270/670 interchange east of the city.
The I-270 Columbus North Central Outerbelt Study conducted in 2004 addresses capacity issues on Interstate 270 between Sawmill Road and Cleveland Avenue on the north side of Columbus. The study contained several options for improving this busy stretch of freeway, including interchange improvements at Ohio 315, U.S. 23 and Interstate 71.
Work completed at the exchange between Interstates 71 and 270 replaced a loop ramp from the Beltway east to I-71 north with a new directional ramp while relocating the ramp to southbound. Just to the west along I-270 at U.S. 23, two loop ramps at the former full cloverleaf interchange were removed, leaving construction to add separate ramps to I-71 from both the eastbound beltway mainline and U.S. 23 on-ramps remains in the future. Work to replace two loop ramps with directional ramps at Ohio 315 has yet to commence as well.
First designated as a route in 1962, Interstate 270 opened the following stages:1
U.S. 23 (Exit 52) to Interstate 71 (Exit 55) - 1966
U.S. 23 (Exit 22) to Ohio 3 (Exit 29) - 1968
Cemetery Road (Exit 13) to U.S. 33 (Exit 17) - 1969
Georgesville Road (Exit 5) to U.S. 40 (Exit 7) - 1970
Two miles north of the west parent junction at Exit 10/Roberts Road of Interstate 270 south. The upcoming Exit 8 interchange is a partial cloverleaf with directional ramps for Interstate 70 east from Interstate 270 south and Interstate 270 south from Interstate 70 west.

Perspective from Interstate 70 east
The first advance signage for the interchange with the Columbus beltway (Interstate 270) is this hazardous cargo sign posted on eastbound Interstate 70. Photo taken by Chris Lokken and Amber Mason (06/23/08).
This mileage sign on Interstate 70 east provides the distance to Interstate 270 (six miles) and the city of Columbus (11 miles). Photo taken by Chris Lokken and Amber Mason (06/23/08).
Use Interstate 270 south to bypass Interstate 70. The beltway circles southeast, then turns east to bypass the downtown section of Interstate 70. The bypass (Interstate 270 southeast) reconnects with Interstate 70 near Reynoldsburg. Photo taken by Chris Lokken and Amber Mason (06/23/08).
The next exit along Interstate 70 east is Exit 91, Hilliard-Rome Road, followed by Exits 93A-B, Junction Interstate 270 (Columbus Beltway). Photo taken by Chris Lokken and Amber Mason (06/23/08).
The right lane of three-lane eastbound Interstate 70 becomes exit only for the connection to Interstate 270. Exit 93A is the link to Interstate 270 east (part of the official bypass of Interstate 70), while Exit 93B connects to Interstate 270 north toward Dublin and the northern suburbs of Columbus. It is also part of the fastest route to Interstate 71 north to Cleveland. Photo taken by Chris Lokken and Amber Mason (06/23/08).
The control city for Interstate 270 south is Cincinnati, which is the southbound control city for Interstate 71. Use Interstate 270 south/east to Interstate 71 south to Cincinnati, U.S. 23 south to Chillicothe and Portsmouth, U.S. 35 southeast to Lancaster and Athens, and Interstate 70 east to Zanesville and Wheeling, West Virginia. Photo taken by Chris Lokken and Amber Mason (06/23/08).
Eastbound Interstate 70 reaches Exit 93A, Junction Interstate 270 east to Cincinnati and Wheeling. The next ramp in this cloverleaf interchange is Exit 93B, Junction Interstate 270 north to Dublin and Interstate 71 north to Cleveland. Photo taken by Chris Lokken and Amber Mason (06/23/08).
Immediately thereafter, eastbound Interstate 70 connects with Exit 93B to Interstate 270 north toward Dublin and the northern suburbs of Columbus. The right lane is exit only. It is only a few miles from this interchange to the western terminus of Interstate 670. Photo taken by Chris Lokken and Amber Mason (06/23/08).
Interstate 70 westbound one mile outside of the Columbus Beltway at Exit 110 for Brice Road. The control points for Interstate 270 feature the Interstate 71 destinations of Cleveland and Cincinnati. Photo taken by Jeff Kitsko (07/10/99).
As displayed on the one-mile guide sign above, Interstate 270 is the mandatory route for all hazardous cargo transports that are not Columbus bound. Photo taken by Jeff Kitsko (07/10/99).
Exit 108A guide sign for Interstate 270 south featuring the designation Columbus Bypass. The first interchange Interstate 270 encounters after Interstate 70 is that of the U.S. 33 freeway at Exit 46. Photo taken by Jeff Kitsko (07/10/99).
The right two lanes of westbound Interstate 70 connect to Interstate 270 west (to Cincinnati) and north (to Cleveland). Photo taken 10/15/04.

Columbus, Ohio - 1972.
By 1972, only the stretch between Morse Road and U.S. 40 remained unopened along the Columbus Beltway. The portion between U.S. 62 near Gahanna and U.S. 40 west of Reynoldsburg was the last built in 1976.
