This project provided a missing and very important link in the I-75/SR 129 interchange by modifying the existing interchange to include access to/from Hamilton-Mason Road and access to/from SR 129 and I-75 to areas east of I-75 in Butler County. A modified collector-distributor style of interchange was designed to include more than four miles of ramps; six diverging/converging gore areas; a new 116’ span prestressed I-beam bridge with integral abutments behind MSE walls; a precast 20’ span arch bridge; widening of a 131’ two span plate girder bridge; and a 15’ high, top-down constructed soil nail wall in front of an existing abutment. New high-mast lighting was provided for the proposed interchange. The overall program also included a $6.42 million widening of 1,300 feet of Hamilton-Mason Road and reconstruction of approximately two miles of Liberty Way and $3.1 million new roadway extension of Cox Road including sanitary sewer and water lines.

Rii provided alternative studies, preliminary design, and final design services to the Butler County TID as part of the Liberty Interchange projects from 2001 to 2009. Rii’s functions on these projects included overall project management, public meetings, coordination with regulatory and local agencies, permitting and environmental documentation, alternative analysis, engineering, production of plans and specifications and cost estimating.
