Akron, Ohio – Akron witnessed a significant advancement in infrastructure development as construction crews initiated the ‘bridge launching’ method on the State Route 8 bridge replacement project. This innovative approach marks the first time the Ohio Department of Transportation (ODOT) has implemented this technique, setting a new standard for bridge construction in the state.
Efficient and Safe Construction Technique
The bridge launching method involves assembling the bridge in sections on the ground and then methodically moving each segment from one pier to the next until it reaches its final position. This method is celebrated for its cost-efficiency and enhanced safety, eliminating the need for construction workers to work at heights, thus reducing the risk of accidents. The sections are built on the ground and then pushed across piers using rollers and hydraulic jacks at a controlled speed of approximately 40 feet per hour.
The first segment launched today measures 196 feet and its placement is expected to take between five to six hours. This marks a pivotal moment in the project as it demonstrates the practical application of this method under real-world conditions.
Progress and Future Phases
Following the successful launch of the initial section, the focus will shift to assembling the next segment, which will extend 230 feet. This part is slated for launch in mid-August. The entire southbound structure of the SR 8 bridge will involve six launches, combining for a total length of 1,600 feet and weighing 8.2 million pounds of steel, with completion expected by January 2025.
Once the southbound bridge is operational, traffic will be redirected to allow for the commencement of the northbound bridge construction, anticipated to start its launching phase in 2026.

Historical Context and Project Overview
The current SR 8 bridge, constructed in 1953, supports over 114,000 vehicles daily. After decades of service and multiple repairs, it has been determined that replacing the bridge is more cost-effective than continuing maintenance on the aging structure. This decision paved the way for the $158 million project that began in August 2023, with an expected completion year of 2028.
