I-270 US-33 NW FREEWAY STUDY

Rapid development in the northwest Columbus vicinity over the past 25 years created pressure on the area's transportation system. Hilliard and Dublin both doubled in size from 1990 to 2000. In total, the area from the Madison County line to the Scioto River and from Trabue Road/I-70 to SR 161 grew in population from 37,000 to close to 70,000 between 1990 and 2000, and it continues to attract residential and commercial development. Employment in this area grew from approximately 28,000 to 55,000 during that time period. Local communities including Dublin, Hilliard, Plain City, Powell, and Brown, Concord, Jerome, Liberty and Washington Townships updated their comprehensive plans to address these continuing growth pressures. In 2003, prompted by these issues, MORPC, the Ohio Department of Transportation (ODOT), the Cities of Columbus, Dublin and Hilliard, and Franklin and Union Counties initiated the comprehensive I-270/US 33 Northwest Freeway Study.

The primary objective of this effort was to develop long-term mobility solutions for the I-270 West Outerbelt area including the US 33 freeway west of I-270 to US 42. The study looked at how best to ease bottlenecks getting on and off the freeways from local streets as well as improving operations on the freeways themselves. The solutions included land-use strategies that minimize the need to travel, transit enhancements, collector and arterial improvements, and freeway and interchange improvements. Study efforts were concentrated on improvements that most directly serve the mobility needs of the corridor's traveling public, and identified costs, potential impacts, and short- and long-term implementation strategies.
