Freeway in Hamilton County, Ohio, United States

Ronald Reagan Cross County Highway, formerly and locally known as Cross County Highway, is a west east freeway in Hamilton County, Ohio, United States. It stretches 16.4 mile (26 km) from southern Colerain Township to Montgomery, connecting many of Cincinnati's northern suburbs to Interstate 71 and Interstate 75. Cross County Highway was built by Hamilton County in seven stages from 1958 to 1997, Highway revolts in Guardian Hill and Crosby Township prevented it from crossing the entire county. Ronald Reagan Highway has a complex junction with Interstate 75 in Cincinnati's Roselawn and Hartwell neighborhoods: southbound I 75 traffic must take Galbraith Road through Arlington Heights and Reading to access Ronald Reagan Highway, and westbound Ronald Reagan traffic must use the same route to reach northbound I 75. Ronald Reagan Highway's abrupt end at Montgomery Road is being converted to a turbo roundabout. State Route 126 continues north and eastward on Montgomery Road through Montgomery and Indian Hill. The majority of Ronald Reagan Highway, between Interstates 275 and 71, is included in the National Highway System (NHS). The NHS is a network of highways that are identified as being most important for the economy, mobility, and defense of the nation. The entirety of Ronald Reagan Highway has two lanes in each direction, with speed limits ranging from
Most guide signs for the highway's entrance ramps bear the name Ronald Reagan Highway, sometimes abbreviated Reagan Highway, rather than control cities. However, signs at the ramps from Interstate 71 onto Ronald Reagan Highway indicate Blue Ash as the westbound destination and Montgomery as the eastbound destination.

Cross County Highway was conceived in the 1940s as a 5 mile (8 km) connector from the Mill Creek Expressway (Interstate 75) to the Blue Ash Airport, which was expected to become Cincinnati's metropolitan commercial airport. In 1950, the concept was upgraded to an expressway; five years later, it grew into a 22 mile (35 km) lateral that would span the proposed Circumferential Highway (Interstate 275). The project, originally estimated at $30 million, In 1959, amid the success of the Greater Cincinnati Airport in Northern Kentucky, officials dropped plans to expand Blue Ash Airport and connect Cross County directly to the airport. In 1963, Hamilton County commissioners asked the Bureau of Public Roads to add the planned route of Cross County Highway to the Interstate Highway System. However, the designation of the Circle Freeway as Interstate 275 the previous fall meant that no additional Interstate mileage could be allocated to the state. The county's master plan, released the following year, envisioned major junctions at the Circle Freeway and Blue Rock Road; a U. S. 27 Expressway paralleling Colerain Avenue that was never built; the Mill Creek Expressway (Interstate 75); and the Northeast Expressway (Interstate 71). Cross County Highway would have bypassed downtown Montgomery, extending eastward from Montgomery Road to connect with Remington Road halfway to Remington, thus providing better connectivity with Loveland and Milford. The highway's abrupt end in Montgomery contributed to a significant increase in traffic to that city: by 1978, Montgomery Road carried an estimated 18,000 cars per day. In 1984, Montgomery city officials unsuccessfully asked the county to either extend the highway east through Indian Hill or truncate it at Interstate 71. Three county proposed routes were rejected by the two villages. Mount Healthy objected to one proposed path because it would have cut through Arlington Memorial Gardens, a major cemetery. In the meantime, the disconnected western segment saw virtually no traffic, encouraging a significant amount of graffiti on bridges and sound barriers. Under the National Environmental Policy Act and Clean Water Act, portions of previously secured right of way were designated as wetland, forcing the county to secure additional land for environmental mitigation. Albert Sabin, the Cincinnati medical researcher, had also been considered for the honor. Reagan wrote to the Cincinnati Enquirer, thanking the county for its gesture and recounting his visit to a Ronald Reagan Pub in the Irish village of Ballyporeen:

text= Don't get me wrong: I'm very proud of that pub, and I know what an honor it is. But I must admit when I thought of something being named after me, I was thinking more along the lines of a building or a highway! I'm honored and touched by the news and pleased to be associated with the city of Cincinnati. Thank you all.|author=Ronald Reagan

The board officially renamed the highway on March 17, 1993, making it the first highway in the country to be named for Reagan. Since then, a number of highways and other landmarks have been named for him. while area residents contacted the Enquirer to suggest Sabin, Lyons, Paul Brown, or Ted Berry. The county raised nearly $15,000 in private donations to install "Reagan Highway" signage. The former President's daughter, Maureen Reagan, dedicated the newly extended highway on September 13, 1994. Construction on the final 4.4 mile (7 km), $39.5 million segment began in October 1994 and completed in 1997. With the highway's completion, travel time across the county dropped from 40 minutes to 17. On October 28, 1997, ODOT took over the highway, except for the segment west of Colerain Avenue. Ronald Reagan Highway also became part of the regional ARTIMIS traffic management system in 1997.

In October 1998, Brayshaw formally requested that ODOT extend Ronald Reagan Highway westward through rural Crosby Township over Blue Rock Road and New Haven Road, to connect the highway to Interstate 74 in Harrison. The roads would be improved in the short term, then eventually widened to a limited access roadway with four to five lanes. Opposition from Crosby Township residents and trustees scuttled the plan. In 2001, Crosby Township again fought a plan by the county transportation improvement district to extend State Route 126 along the remainder of Ronald Reagan Highway, Blue Rock Road, and a new bypass around New Baltimore to a junction with State Route 128. The highway's oldest 3.7 mile (6 km) were upgraded to modern freeway standards from spring 2000 to summer 2001 for $17.6 million. In addition to repaving the highway, ODOT replaced the center guardrail with a Jersey barrier, replaced curbs with wide shoulders, lengthened on and off ramps, and installed new overhead guide signage. West Side communities have seen significantly increased commercial development since the highway's completion, attributed in part to decreased congestion on surface streets. Originally, Ronald Reagan Highway had an unsignalized, at grade intersection at the Interstate 71 interchange, requiring traffic from southbound I 71 to cross continuous westbound lanes of Ronald Reagan Highway and merge into continuous eastbound lanes of that highway. In 2017, Montgomery city officials proposed turning the entire interchange into a turbo roundabout. Instead, traffic signals were added to the intersection in 2018.

Before traffic signals were installed in 2018, the intersection between eastbound Ronald Reagan Highway and the entrance ramp from southbound I 71 was the most crash prone stretch of roadway in the Greater Cincinnati area, with 666.39 collisions and 102.53 injuries and fatalities on average annually, The intersection between the westbound exit ramp of Ronald Reagan Highway and Colerain Avenue had 20 collisions in 2014 (none of which involved injuries), making it the fifth most crash prone intersection on a Hamilton County road that year. On August 15, 1998, a Cessna 152 departing from Blue Ash Airport bound for Cincinnati/Northern Kentucky International Airport ran out of fuel and collided with a car, killing three, as it attempted an emergency landing on Ronald Reagan Highway.
