The Renovation of the I-77 Bridges Over Kingsbury Run, 2002
Owner: The Ohio Department of Transportation
Location: Cleveland, Cuyahoga County
Nominated by: Anthony D. Yacobucci, P.E., HNTB Ohio, Inc.
Description: The I-77 bridges at Kingsbury Run provide a vital transportation link to downtown Cleveland from the south. Despite earlier repairs, the spans had continued to deteriorate and had become a serious safety concern. The renovations eliminated non-redundant and fatigue critical members in the superstructure, and overstressed foundation piles and footings. As part of the renovations, the spans were widened to accommodate increased traffic volume. The replacement structure is designed to carry higher AASHTO traffic loads but uses 13% less structural steel. Four lanes of traffic, two in each direction, were maintained during construction, this being accomplished partly by closing some access ramps and directing local traffic to alternate routes that are still being used by many commuters. The design was completed in a compressed 14-month schedule to qualify for FY Federal renovation funding.
