Dublin is hoping to continue work on a possible I-270/U.S. Route 33 interchange solution and is asking for $6.75 million from the state to do so.

Both local and state funds have gone into some preliminary work and Dublin recently submitted a grant proposal to ODOT's Transportation Review Advisory Council, or TRAC, for more money.

"We're asking for $6.75 million to complete preliminary engineering," Dublin Assistant Engineer Jeannie Willis said. "It would get us basically finished up with the environmental documents and get the full interchange design drawings to 60-percent complete. Dublin has agreed to a $2.25 million match for a total of $9 million."

So far, very preliminary work has been done with a $2 million grant Dublin received in 2010 for improvements to the cloverleaf interchange that was built in 1967. No major changes have been made to the interchange since its construction.

"We've been working on refining alternatives and working toward the selection of a preferred interchange footprint," Willis said. "We still have four alternatives on the table, including a no-build (alternative) that we're reviewing them with ODOT to choose the preferred alternative."

According to information from Dublin, the interchange serves more than 34,000 employees at 1,000 businesses, including Honda, Scotts Miracle-Gro and Industrial Parkway businesses.

The interchange is 20 percent over capacity and is in the top 10 in the state for freeway crashes, Willis has previously told Dublin City Council.

The first phase of the multi-year project would be a northbound I-270 to westbound U.S. Route 33 flyover ramp. Willis said Dublin is hoping the first phase will be constructed by 2017.

"It solves the weaving issue we have on (interstate) 270 underneath the (U.S. Route) 33 bridge and would help to improve safety and operation of the interchange immediately," she said.

TRAC will not announce its next round of funding until next spring, Willis said, but a public hearing on funding will be held this fall on a day yet to be determined.

Local residents and businesses can help support the project with letters and comments.

Dublin recently improved its project website at 27033interchange.org, which includes ways to get involved, information on the project and maps.

"There's a button that says 'Take action.' You can leave a comment, write a letter or write a letter to the editor," Willis said. "It would all be very helpful."
