STATE OHIO State funding focuses on repair and replacement of local bridges by Pieter Wykoff and Tim Keller, Ohio Department of Transportation With nearly 28,000 bridges, Ohio ranks second in the nation for the number of bridges connecting state and local roads. These are all critical to the state’s transportation infrastructure. Most of these bridges are shorterspan bridges on local road systems, but the large Ohio inventory also contains a number of major, iconic structures. Several of the more-recently constructed concrete bridges in this category have been featured in past issues of ASPIRE.TM These include the Veterans’ Glass City Skyway in Toledo (Summer 2007), the Rich Street Bridge in Columbus (Fall 2012), and the Jeremiah Morrow Bridge in Warren County (Winter 2014), all of which are owned by the Ohio Department of Transportation (ODOT). A brief description of each of these beautiful concrete bridges follows. Veterans’ Glass City Skyway—Toledo The Veterans’ Glass City Skyway Bridge carries Interstate 270 (I-270) across the Maumee River at Toledo, Ohio. The cable-stay supported main spans reach 612.5 ft on each side of the single tower. The entire structure is 8800 ft long and was constructed using 3050 precast concrete box-girder segments. In the main spans, the twin boxes are connected using delta frames that transfer loads from the box girders to the cable stays. The sides of the tower are encased in glass that is reflective during the day and is lit from behind with arrays of multi-colored LEDs at night. The bridge was opened to traffic in 2007. Rich Street Bridge—Columbus The Rich Street Bridge crosses the Scioto River in the heart of Columbus, Ohio. The new five-span bridge is 563 ft long and carries three lanes of traffic and two 10-ft-wide sidewalks. Precast semi-lightweight concrete arch segments support haunched precast concrete girders and a cast-in-place concrete deck. All elements of the structure were post-tensioned for structural efficiency and durability. The bridge was completed in 2012. Jeremiah Morrow-Warren County The Jeremiah Morrow Bridge is the tallest bridge in Ohio and is the first cast-in-place segmental concrete box-girder bridge to be constructed in the state. The six-span twin bridges carry Interstate 71 (I-71) nearly 240 ft above the scenic Little Miami River in Warren County, Ohio. The two main spans are 440 ft long. The single-cell box girders have a top flange width of 55 ft and vary in depth from 12 ft deep at midspan to 25 ft deep at the piers. The northbound bridge was opened to traffic in 2013; the second bridge is still under construction with completion expected in the fall of 2016. Improving Local Bridges The Buckeye State’s bridge inventory is better than most when it comes to nationwide reports on statewide bridge conditions, but the ODOT continues to rehabilitate and repair bridges on most interstates, and U.S. and state routes. Many of the bridges on local routes, which are owned and maintained by counties and cities, are in need of more-costly repairs. To address the condition of these local bridges, Governor John R. Kasich launched the Ohio Bridge Partnership Program in 2013 to help cities and counties repair 220 local bridges. The three-year, $120-million program started the following year by fixing the first 40 structurally deficient bridges on the local transportation system. Reductions in original cost estimates allowed program planners to add 10 more bridges to the list in 2014, bringing the total number of bridges receiving repairs to 230. The next transportation budget provided an additional $10 million to the program, extending the program through 2017. In 2015, 84 local system bridges in Ohio were slated for reconstruction as part of the program. “It’s been a much-needed shot in the arm for
