Welcome to the Brent Spence Bridge Site


The Brent Spence Bridge opened in 1963 as the Ohio River crossing for I-75, the first of four bridges in the Cincinnati area built as part of the Interstate Highway System. The bridge is a typical example of the cantilever truss design, with a main span of 830.5 ft. and two approach spans each measuring 453ft. It was originally built with 6 lanes divided between two 3 lane decks, however the emergency shoulders were eliminated in 1986 and the decks rebuilt with 4 lanes each. Traffic has overwhelmed the bridge for decades and planning is currently underway for its replacement, which will be built sometime after 2010, and is estimated to cost as much as $500 million.
