Fun facts on the 8th Street Viaduct (courtesy the City of Cincinnati):

  • Designed in 1927 by Hamilton County and State of Ohio Department of Highways, the Eighth Street Viaduct was constructed in 1929.
  • It is the second oldest viaduct still in existence in Cincinnati.  The Hopple Street Viaduct, which was constructed in 1916, is the oldest.
  • The viaduct is owned by Hamilton County and maintained by the City of Cincinnati.
  • The viaduct spans over CSXT and Norfolk Southern Railroads and the Mill Creek.
  • The Eighth Street Viaduct is one-half mile long.  Most people believe it is longer because they believe the bridges over Evans and Burns Streets are part of the viaduct.  Those bridges are separate structures
  • The viaduct roadway is 56 feet wide with four lanes of traffic and two bicycle lanes.
  • Viaduct made up of 79 spans of reinforced concrete beams.
  • This reconstruction project includes the replacement of 22 piers (supports), sidewalks, railings and roadway.  Additional work includes structural patching and coating of concrete and replacement of all street lights on the viaduct.
  • The last rehabilitation of the viaduct was in 1974 and was contracted at a price of $904,596.  The current construction contract is $21,798,992.
