According to a Dispatch article this morning, ODOT has approved plans to divide the 70/71 Split project into two parts. The first being the eastern leg of 71 through Downtown running between I-670 and I-70, with a $512 million price tag. The second leg is the actual split running through the south end of Downtown where interstates 70 and 71 overlap. This second portion has been downgraded to a Tier II Funding Request, which means that the funding from ODOT has not been approved as of yet, and this part of project is not actually guaranteed to happen anymore.
The eastern portion of I-71 is home to the majority of the crash problems, and the article makes it sound as if ODOT is fully dedicated to fixing the neighborhood connectivity issues by committing $10 million towards building caps, potentially on the Spring, Long, and Broad Streets bridges. MORPC has also previously pledged an additional $12 million for highway caps. The full Dispatch article can be read here.
More information on the project can be found on the official ODOT project website.
