Construction is complete on the SR 161/Post Road improvement project at the U.S. 33 interchange. The $40 million initiative, a partnership between the Ohio Department of Transportation (ODOT), the city of Dublin, the Union County Engineer's Office and the Mid-Ohio Regional Planning Commission (MORPC), delivers a safer, more efficient interchange to serve the growing region.
The project involved a full reconstruction of the interchange, including new ramps and two loop ramps designed to eliminate left-turn conflicts. The new U.S. 33 eastbound ramp now connects directly to the Eiterman Road roundabout, while the westbound ramp aligns with an upgraded signal at Hyland Croy Road. The project also included resurfacing U.S. 33 and replacing and widening the bridge carrying U.S. 33 over S.R. 161/Post Road.
"This project represents a significant investment in safety, mobility and connectivity for our region," said Megan O'Callaghan, city manager, city of Dublin. "We appreciate our partnership with ODOT, MORPC and Union County in bringing this transformative improvement to life. Thank you to our residents, commuters and businesses for their patience and understanding throughout the construction process. Your cooperation helped make this gateway to Dublin safer and more efficient for everyone who travels through our community."
"This interchange is truly a critical connection between the city of Dublin and Union County," said Toni Turowski, ODOT District 6 deputy director. "A better functioning interchange will help move people between these growing areas with greater safety and efficiency."
Both U.S. 33 and Post Road are heavily traveled routes vital to regional mobility, requiring the project to be completed in phases to maintain traffic flow.
"We know this construction had a major impact on daily commuters, and we thank everyone for their patience," Turowski said. "Keeping traffic moving and the project on schedule was a tremendous accomplishment. We appreciate the collaboration with Complete General and the city of Dublin. Projects of this scale are only successful when strong partners work together."
