about in each. US 42 crosses into Cincinnati from Covington, Kentucky, on the Clay Wade Bailey Bridge, together with US 127. US 42 heads northeast out of Cincinnati on Reading Road, which runs between I-71 and I-75. In 2020, the Cincinnati City Council approved a project to rename Reading Road to President Barack Obama Avenue from Downtown Cincinnati to Reading, pending private donations; all 30,000 signs are expected to be installed by September 2021. Reading Road intersects with I-275, then briefly enters Butler County. The Ohio Department of Transportation has given this portion of US 42 the name Columbus–Cincinnati Road, but it is locally known as Cincinnati–Columbus Road, a name that also appears on West Chester Township signs along the road. The portion of US 42 in Warren County between Lebanon and Waynesville is designated "Sergeant Brian Dulle Memorial Highway", in honor of a Warren County Sheriff's deputy who was struck and killed along US 42 on May 10, 2011 by a stolen car, while he was laying out stop sticks to catch the driver. The intersection with Spring Valley–Paintersville Road in Spring Valley Township, Greene County near the village of Spring Valley has been the site of numerous fail-to-yield accidents, including a double fatality in 2017. In October 2018, the Ohio Department of Transportation announced that it would convert the intersection into a "basic RCUT", which would add a median and replace all left turns with right-in/right-out turns and median U-turns. The project is expected to cost around $1.2 million and begin in late 2020. In Xenia, the intersection of US 42 (North Columbus Street) and East Church Street, where US 42 formerly continued at an awkward angle, was converted to a roundabout on June 12, 2020, at a cost of approximately $1.1 million. After leaving Xenia, major cities along the route are London, Delaware, Mansfield, Ashland and Medina prior to reaching the Cleveland metropolitan area. In London US 42 intersects with I-70. Other than a short concurrency at each end, in Delaware are the only other two concurrencies with US routes. Entering Delaware from the south US 42 runs concurrent with US 23 in Delaware until the junction with US 36 which it follows east for about before turning back to the north. The concurrence with US 23 is the only stretch of US 42 that is categorized as a freeway in Ohio. Heading into Cuyahoga County at
