Interstate 270, U.S. Route 33
State funding puts upgrades on faster track
Construction could start in late 2014, wrap up by 2016
A state board last week approved $50 million for improvements at the Interstate 270/U.S. Route 33 interchange on Dublin's west side.
The Transportation Review Advisory Council on Sept. 27 approved the funding for the interchange that has remained largely unchanged since its construction in the 1970s.
The existing interchange is failing, and according to information from Dublin, 292 crashes occurred there from January 2010 to December 2012.
The influx of state funds from Ohio Gov. John Kasich's $3 billion "Jobs and Transportation Plan" moves up the timetable for improvements, with construction on the project that could cost more than $90 million expected to start as soon as late 2014.
The Mid-Ohio Regional Planning Commission has committed $25 million to the project and Dublin has set aside $17.25 million.
The Ohio Department of Transportation has already spent $1.5 million on it.
"ODOT, MORPC and our local residents and businesses have been great partners in moving this project forward," Dublin City Manager Marsha Grigsby said in a release from the city. "The city of Dublin welcomes and applauds this action, which allows us to replace an outdated, unsafe interchange, reduce traffic delays and provide opportunities for continued regional economic growth and job creation."
The improvements will change U.S. Route 33 from three lanes east and west to four between the interchange and the Avery-Muirfield Drive exit. New ramps will be built to replace the clover-leaf configuration, including specific lanes for traffic exiting from I-270 south to U.S. Route 33 west to exit at Avery-Muirfield.
A traffic light also is planned to regulate traffic on eastbound Route 33 for traffic exiting from I-270 northbound.
A second phase of construction will install a flyover ramp from I-270 northbound to Route 33 west.
If construction for the first phase begins in late 2014, the project could be completed as soon as 2016.
Environmental studies are ongoing and a preliminary design is expected later this year.
