Major reconstruction of I-75 from Cincinnati-Dayton Road in Butler County to State Route 122 in Warren County is taking place. With this section of roadway carrying an average daily traffic count of 87,000 vehicles, the project is designed to improve safety and ease congestion.
The $98 million project includes 11 mi. (17.7 km) of pavement rehabilitation and the addition of one lane, southbound and northbound, in the median of I-75. Work also includes grading, drainage and resurfacing of the existing pavement. In addition, 12 mainline and overhead structures will receive improvements during this project.
The Bethany, Princeton, Millikin and Kyles-Station overpasses in Butler County will get new decks and profiles while the deck will be replaced on the Greentree and Hendrickson overpasses in Warren County.
The Tylersville Road and Hamilton-Mason structures’ decks will be resealed and the ramps at Tylersville Road will be repaved. In addition, noise walls will be installed along I-75 from Union Centre in Butler County to State Route 63 in Warren County.
The Bethany Road overpass reopened to traffic July 31. The Princeton Road overpass closed to traffic Aug. 4 for 75 days with local detours posted. The Kyles Station overpass was closed until mid September with local detours posted.
The State Route 63 overpass also saw more work with the construction of a Single Point Urban Interchange or SPUI which uses one set of traffic signals to control all through and left turn traffic from and onto the interstate.
Ramps will be widened and reconfigured to accommodate the SPUI interchange, and SR 63 will be reconstructed on both sides of the interchange, from Lawton Avenue to the west, and to tie in with recent reconstruction to the east. That work is expected to take place in 2009.
Currently, three lanes of traffic on I-75 in each direction are being maintained with traffic shifted to temporary pavement from Tylersville Road to Cincinnati-Dayton Road. The speed limit through the construction zone is posted at 55 miles per hour.
The completion date for this project is scheduled for the fall of 2011.
