^Looking eastbound just before the Exit 9, which leads to the Columbus Airport, April 2021.
Interstate 670 runs east-west across the Columbus area. Interstate 670 flanks the north side of downtown Columbus. It is a northern alternative to Interstate 70, which flanks the southern edge of downtown Columbus. Interstate 670 begins by splitting from Interstate 70 west of downtown. The freeway runs northeast from the downtown area to serve the international airport. It then ends at Interstate 270 near Gahanna.
As with all of the Ohio Interstate pages, more information and a full exit list will come in the future. For now, enjoy this general information and a photo of the signage, in a similar fashion to how I do the state and US highway pages.
