Mega Project nearing completion
Two years after construction started on the largest ODOT project in Central Ohio, the
I-71/670 Columbus Crossroads Project, there are signs, literally, that completion is near. By the middle of November, all highway travel movements, which includes every lane and bridge on I-71/670 will be open.

The scope of the Columbus Crossroads project includes 22 new bridges, more than 30 retaining walls and the start of two new city streets. All of which will increase capacity and improve safety on a highway that was built in the 1960s.

Drivers need to remember two things: Read and follow the signs.

About Columbus Crossroads
The Columbus Crossroads project, one of the largest highway projects in Ohio, has been under construction since 2011. This first phase of I-70/71 construction will be completed in 2014. The $200 million I-71/670 project will improve safety, reduce congestion, and connect neighborhoods. It will add a new travel lane on I-670 and reduce weaving across traffic lanes to exits. Twenty-two new bridges will be built, including one with a first of its kind cultural wall designed with community input.

ODOT Saves $41 Million and Six Months of Construction
Using a value-based, design-build process that combines design and construction in one contract, ODOT is able to improve operational efficiency, reduce disruptions and more quickly deliver a high-quality finished project. ODOT awarded the contract to Kokosing Construction Company and CH2M Hill who are able to build the project for $200 million after original estimates pegged the cost at $241 million.

Neighborhood Features
Two urban avenues and gateways into downtown Columbus are part of the new project design. Through a partnership with the City of Columbus and the Mid-Ohio Regional Planning Commission (MORPC), the Long Street Bridge will feature landscaping, green space, decorative lighting, sidewalks and a cultural wall on a 220’ cap. Similar landscaping and design elements will be incorporated into the Spring Street Bridge.

Keeping You Safe
During construction, safety remains a high priority. Traffic will be slowed to 45 mph, with traffic lanes on I-71 and I-670 remaining open over the duration of the project. Ramp and road closures will be posted on this website and publicized to help you allow more time to get to your destination safely.
