In January 2006, the South Carolina state legislature introduced bills to construct I-73 as a toll highway. It is hoped a guaranteed stream of revenue will allow it to build its section of I-73 within 10 years. The FHWA approved South Carolina's proposal on August 10, 2007.

proposed allowing tolls to be collected on newly built sections of highway. One of the proposed routes includes the Columbus–Toledo corridor, which is currently served by US 23 as an expressway largely without limited access.
A new project has been initiated by ODOT to complete a study of the US 23 corridor between the village of
Waldo and
I-270. The goal of this project is to create a free-flow connection between Columbus and Toledo. Some of the alternatives to be explored include upgrading the existing alignment or creating new corridors to

However, Congress amended that definition in 1995 to have a branch along the

MDOT abandoned further study of I-73 after June 12, 2001, diverting remaining funding to safety improvement projects along the corridor. The department stated there was a "lack of need" for sections of the proposed freeway, and the project website was closed down in 2002.
According to press reports in 2011, a group advocating on behalf of the freeway was working to revive the I-73 project in Michigan. According to an MDOT spokesperson, "to my knowledge, we're not taking that issue up again".
[ The Lenawee County Road Commission is not interested in the freeway, and, according to the president of the Adrian Area Chamber of Commerce, "there seems to be little chance of having an I-73 link between Toledo and Jackson built in the foreseeable future."]
