Travel directions

I-270 near Dublin on the northwest side of Columbus.

The start and end point is on the south side of the city, at the interchange with Interstate 71, the highway from Cincinnati to Columbus. The highway then runs 2×3 lanes to the west, through the southern suburbs. At Lincoln Village, one crosses Interstate 70, the highway from Indianapolis and Dayton to Columbus. After that, 2×3 lanes are also available and you pass through an industrial zone. At Dublin, a suburb northwest of Columbus, one crosses US 33, a highway to the northwest. The highway then turns to the east and has 2×4 lanes. On the north side of the city one crosses theSR-315, the highway to downtown Columbus. After this, even 2×5 lanes are available. Not far after that, Interstate 71 crosses again, which leads toward Cleveland. Then the road narrows again to 2×4 lanes.

At the suburb of Minerva Park, the road turns south and intersects SR-161, the New Albany Expressway toward New Albany. The highway then has 2×3 lanes, but also has 3 lanes of wide parallel lanes on both sides of the highway. At Columbus Airport, Interstate 670, an east-west highway in the city ends. After that, 2×4 lanes will be available again, which will then become 2×2 with 2×4 parallel lanes. One then crosses Interstate 70 again at Whitehall, which runs towards Wheeling and Pittsburgh. Then the road narrows to 2×3 lanes. One then returns to the south side of town where the road at I-71 rejoins the starting point.

History

Construction history

Construction on the beltway began in 1962, both north and south of Columbus near the recently opened portions of Interstate 71. The first portions opened to traffic between 1965 and 1969, but by about 1970-1971, large portions of the beltway were closed. opened for a short time, especially along the west and north sides of Columbus. The section along the south side was also completed quickly. The eastern part of the ring road was opened in phases between 1971 and 1975. With this, the entire ring road was completed in 10 years as planned.

South ring

The eastern portion of the Columbus South Ring between I-70 and US 23 had 2×3 lanes prior to 1994 and may have been constructed directly with 2×3 lanes. This includes the western portion of the South Ring between I-71 and I-70. In 2014-2015, the middle portion of the South Ring between US 23 and I-71 was widened from 2×2 to 2×4 lanes.

Western string

The western part of the ring road is presumably built directly with 2×3 lanes.

North ring

The North Ring between US 33 in Dublin and I-71 in Worthington was originally constructed as 2×2 lanes and was widened to 2×4 lanes in the mid 1990s. In the second half of the 1990s, the eastern portion between I-71 in Worthington and OH-161 at Huber Ridge was also widened to 2×3 lanes. Around 2007 this was further widened to 2×4 lanes.

The interchange between I-270 and I-71 in Worthington was originally a two-arch, 2-loop clover turbine. In 2007-2008 the interchange was reconstructed with a flyover from the west to the north and a realigned link road from the west to the south.

The connection between I-270 and US 23 in Worthington was originally a cloverleaf cloverleaf, but was reconstructed into a parclo with 6 connecting roads in 2015 in connection with the upgrade of US 23 north of I-270. The connection to OH-710 at Westerville was reconstructed in 2015 from incomplete cloverleaf to parclo with 6 connecting roads.

Oostring

The East Ring was already quite spacious at the time, with 2×3 lanes between OH-161 and I-670 and 2×4 lanes between I-670 and I-70, including a short 12-lane parallel structure between US 40 and I-70. In the second half of the 1990s, a parallel structure was built between OH-161 and Easton Way. The highway was also widened to 2×4 lanes further to I-670 at Gahanna.

The interchange between I-270 and OH-161 was originally a cloverleaf cloverleaf. In 2007 this was reconstructed into a hybrid stack turbine node, in conjunction with the widening of OH-161.

Traffic intensities

The southwest portion between I-71 and I-70 is fairly quiet with 58,000 to 86,000 vehicles in 2×3 lanes. After that, the west ring peaks at 103,000 vehicles. The northern section is busier with 157,000 vehicles off SR-315. The eastern ring has a maximum of 143,000 vehicles. The southeast ring has 67,000 vehicles. Sufficient capacity is available and there is no large-scale congestion.
