Cincinnati, Ohio and Northern Kentucky - 1973
The westbound direction of Interstate 275 was shown as complete between the four-level interchange with I-71 & 75 at Erlanger and Kentucky 212 to then Greater Cincinnati Airport. The remainder of the beltway in Kentucky was under construction or proposed.
Interstate 275 follows the Circle Freeway around the Cincinnati, Ohio metropolitan area. The beltway includes a concurrency with Interstate 74 and two high level bridges across the Ohio River. This is the only three-digit Interstate highway that enters three states, including one state (Indiana) that its parent does not enter.
The Circle Freeway mostly acts as a commuter route for the various suburbs of Cincinnati, Covington and Newport, Kentucky. The route also provides a bypass from southeast Indiana to northern Kentucky and part of an alternate route around the Brent Spence Bridge of I-71 & 75 across the Ohio River.
With some portions of Interstate 275 in Ohio already opened by 1961, certification of the route occurred in 1962. The beltway was fully completed in the Buckeye State by 1980.1 It was formally named the Donald H. Rolf Circle Freeway in 1982.5 The short stint of I-275 through Indiana, including the Carol C. Cropper Bridge over the Ohio River, was finished in 1979.2
The course of I-275 through Boone County, Kentucky was chosen from a desire to include Indiana in the planning for a Greater Cincinnati circle freeway. The idea for a new bridge spanning the Ohio River from Boone County dated back to the early 1950s with support of Boone County Judge Carroll Cropper and U.S. Representative Earl Wilson of Indiana. A bill was introduced by Rep. Wilson in April 1956 for the establishment of the Lawrenceburg Bridge Company. It involved financing construction of a new span with a bond issue and paying bonds off with tolls. The bill passed, but with 1958 cost estimates of $10 million for the bridge, progress crawled.4
Planning was underway during the late 1950s for the Circumferential Highway through the Cincinnati suburbs east from U.S. 50 in Cleves to U.S. 25 in Clermont County. Those plans were eventually combined with the Boone County bridge concept in November 1961 as part of the Greater Cincinnati Metropolitan Area Bypass.4
Renamed the Circle Freeway, the Federal Bureau of Public Lands approved the alignment for I-275 across Northern Kentucky in March 1963. The 24-mile route was estimated to cost $50 million and land acquisition was underway by 1967.3
The Ohio River crossing at Boone County was selected for Petersburg instead of a location closer to Lawrenceburg, Indiana. Bids for construction on the new bridge were taken by the state in March 1968, with on the four main piers in the Ohio River underway by June 1968.4
Pier construction extended to summer 1972, when work started on the steel floor beams of the bridge. The bridge project culminated in Kentucky in May 1974, leaving just the deck to be completed. However on the Indiana side of the river, contracts for I-275 paving were just being awarded. As such, the bridge was relegated to sit idle for several years.4
A dedication ceremony was scheduled for December 6, 1977, but a major snowstorm forced the event to take place indoors and delayed the bridge opening. Bridge proponent Carroll Cropper did not live to see the span completed, but he was honored as the bridge's namesake by Governor Julian Carroll.4
The Kenton County portion of Interstate 275 was finished on November 10, 1977 with the opening between U.S. 25 (Dixie Highway) and Kentucky 16 (Taylor Mill Road).5 The remainder of I-275 across Kentucky was completed in December 1979,4 with the dedication of the Combs-Heel Bridge in Campbell County on December 19. The cantilever bridge is named for Governor Bert Combs and Campbell County Judge-Executive Lambert Hehl.5
