Interstate 75 runs across western Ohio from the Brent Spence Bridge spanning the Ohio River at Cincinnati to the Michigan state line just west of Maumee Bay and Lake Erie. 212 miles long in the Buckeye State, I-75 joins the Queen City with Dayton, Lima, Findlay and Toledo.

Interstate 75 Ohio Guides

Within the Cincinnati area, I-75 enters Ohio overlapping with I-71 north from Covington, Kentucky. The two part ways at the north end of the Brent Spence Bridge, with I-71 turning east through Downtown and I-75 staying north through the West End and Camp Washington neighborhoods. I-75 continues through urban areas northeast to Sharonville, where it meets Interstate 275, the beltway encircling the Cincinnati area.

Continuing into Butler County and the north Cincinnati suburbs, very little of I-75 is rural en route to Dayton. I-75 leads directly to Downtown Dayton while I-675 bypasses the city and Kettering to the east. I-675 provides a more direct route to Wright Patterson Air Force base and I-70 east to Columbus. I-75 meets I-70 at Vandalia.

Leaving the Dayton area, Interstate 75 heads north to Troy, Piqua and Sidney, where Business Loops were once designated. I-75 shifts east around Lima and then northeast to Findlay. Directly overlaying portions of former U.S. 25, the freeway continues north to Bowling Green and into Perrysburg where I-475 branches west. I-475 encircles Toledo from Maumee north to U.S. 23 near Sylvania and east back to I-75 by Downtown. I-75 passes Downtown to the east before curving northeast to meet I-280 and cross the Michigan state line at Shoreland.
