Owner Objective
The Ohio Turnpike and Infrastructure Commission (OTIC) is the state agency that owns and operates the Ohio Turnpike. The Ohio Turnpike is a 241 mile toll road, traversing the entire state, and connects to the toll roads in the adjacent states of Indiana and Pennsylvania. OTIC is responsible for the construction, operation, and maintenance of the Ohio Turnpike. OTIC required an engineering firm to address the deterioration of the Bad Creek Bridges at milepost (MP) 41.3 and also widen them to add an additional lane of traffic in each direction to facilitate the third lane widening program.
CEC Approach
CEC performed an in-depth field inspection of the bridges at MP 41.3 to assess the deficiencies and determine the extent of the rehabilitation required. To ensure the sufficient structural capability of the rehabilitated structures, the bridges were load-rated, determining their carrying capacity. Additionally, a thorough, “hands-on” inspection was conducted on the primary structural members, including non-destructive testing of the steel and concrete members. Inspection crews looked for section loss, deterioration, fatigue cracks, concrete cracking and spalling, and other deterioration.
The 3 span bridges (one for eastbound and one for westbound) have a main span of 33’-6” with two end spans of 31’-6” and a total length 117’-6”. The proposed work includes removal of the existing concrete deck and widening the substructures towards the median. The widened reinforced concrete abutments will be supported on new HP 10×42 piles, and two new piers will be supported on 3-ft. thick spread footings. New W27 rolled beam sections at 7’-6” spacing will support the widened deck. A new reinforced concrete deck will be installed with single slope parapets. The project will be performed in two phases based on the Maintenance of Traffic scheme. The proposed widening gives each bridge a Final Typical Section of 60’-3 1/2” roadway width from toe to toe of parapets, supporting 3 lanes of traffic in each direction.
