[ARCHIVED] Diverging Diamond Interchange (DDI) Project


The City of Solon, in conjunction with the Ohio Department of Transportation, has proposed a project that will include the reconfiguration of the US-422 interchange at Harper Road (CR-18) in Solon, Cuyahoga County, Ohio. Work will include the construction of a Diverging Diamond Interchange (DDI) to improve mobility, traffic flow and safety. In addition, the proposed project will include the following:

  • Removal of the US-422 west bound loop ramp.
  • The newly constructed US-422 west bound ramp will be widened to two (2) lanes to allow for a left turn lane and a right turn lane onto Harper Road.
  • Removing pavement along Harper Road and replacing with an asphalt concrete pavement section.
  • The addition of a 6-foot-wide sidewalk on the west side and a 10-foot-wide dual-use-path on the east side of Harper Road.

The City of Solon welcomes your questions and comments. Issues you may wish to comment on could include, but are not limited to, the effect of the project on local residents, air quality, the local economy, floodplains and historic or cultural resources.
