Liberty Interchange

In late 2002, the TID started the environmental work of the project. The study area for this project extended from Tylersville Road to just south of State Route 63 (north-south boundary) and Cincinnati-Dayton Road to Butler-Warren Road (east-west boundary). The approval process took over six years and was approved in April 2008 by Federal Highway Administration. 

Simultaneous with the environmental process, the TID moved forward with the detailed design which also included engineering work for local roadway improvements around the interstate interchange.  

The preferred alternative selected created a collector-distributor interchange with Hamilton Mason Road (now named Liberty Way) overpass. The local roadway improvements included widening Liberty Way from Butler-Warren Road to Cincinnati Dayton Road and extending Cox Road north approximately 2500 feet.

The three local governments (BCC and Liberty and West Chester Townships) agreed to finance the project costs through a bond issue backed by a financing agreement with the three parties in early 2007.

In 2008 the TID secured the right-of-way for the interchange construction project and the construction contract was awarded in early 2008 to John R. Jurgensen Company for $14.3 million. ODOT was responsible for the main interchange and related improvements to Interstate 75. The TID awarded separate contracts for the other three phases for the overall project. In total all the construction took two seasons. In August 2009, the project was completed and open to the public.

Later in 2016, the TID refunded the initial bond issued because of lower interest rates savings the participating governments millions of dollars.
