I'm not sure how to make any changes, and as a level 1 map editor the intersection is off-limits anyways - but two major ramps are closed in Columbus today, for the next month. The Paving the Way link is http://www.pavingtheway.org/i-270/
"The ramp from I-270 north to I-70 west and the ramp from I-70 east to I-270 north will close June 4 for 30 days. The closures are necessary to reconstruct the ramps. Before those ramps close, the ramp from I-270 north to I-70 east will re-open. The detour for I-270 north to I-70 west will be I-270 north to Cemetery Road to I-270 south to I-70 west. The detour for I-70 east to I-270 north will be I-70 east to Wilson Road to I-70 west to I-270 north. (ODOT)"
It's kind of a big deal. Maybe some day I'll get better at this.
