Event Details

Field Trip to the Jeremiah Morrow Bridge Replacement

Speaker: Dan Mendel, P.E.  ODOT Warren County Resident Engineer

 

Mr. Mendel has been with the Ohio Department of Transportation for 25 years constructing bridges, highways, and retained structures throughout much of Southwest Ohio.

 

Abstract:  At 239 feet high, the Jeremiah Morrow Bridge is Ohio’s tallest bridge and our nation’s 25th tallest bridge.  Consisting of two separate structures on Interstate 71, these bridges span 2,440 feet to cross the Scenic Little Miami River Valley and a recreational bike trail.  Interstate 71 is Ohio’s major interstate route which connects the cities of Cincinnati, Columbus and Cleveland.  The JMB is located 34 miles north of downtown Cincinnati and 71 miles south of I-70 in Columbus.  This project replaces two existing steel deck truss bridges built in 1964 which have deficient shoulder widths and load restrictions of 80,000 lbs  with two new bridge structures.  The new bridges consist of longitudinal and transverse post tensioned single-cell segmental concrete box girder structures.  Due to limited R/W, area terrain and environmental considerations, cast-in-place balanced cantilever method of construction was specified.  While this type of bridge is more common in southern states, it is not common in Ohio. However, through a bridge study with a primary driver of future maintenance costs that considered bridge painting, the segmental concrete box girder type structure was selected. This project, which is currently active and approximately 46 percent complete, began in June 2010 and is set for completion in June of 2016. 

 

The ASCE members will be eating their box lunch while Mr. Mendel provides a presentation on the existing and new bridge structures.  The presentation will last about one hour with the site tour to follow.
