A road construction project that’s done in under 30 days – it’s almost unheard of! But in Muskingum County, Ohio, that’s exactly what happened. A bridge needed replacement and initial estimates were that construction of the new would take 30 days. The work was done in 26 days using an SPS bridge.
Quality Work Quickly
The SPS bridge, the first of its kind in Ohio, is designed to last for 100 years. The primary characteristic of SPS bridges is their modular design. As a result, sections each weighing approximately 31 tons, were built and placed in just 10 minutes each. This modular structure also allowed for the bridge to be built offsite and then brought to the site by truck and put together. As a result, what would normally take three to four weeks, only took 20 minutes.
“As a steel bridge manufacturer and a general contractor, we recognize and appreciate accelerated bridge construction and so do our customers. On this project, the design of the girders paired with the SPS deck, permitted our crews to completely replace the old structure in record time. From bridge and abutment demolition to new abutments and superstructure, this bridge was open to traffic in 26 days. Remarkable.”

SPS Bridge is Built to Last
The SPS bridge is simpler and more lightweight than its predecessor, while still capable of withstanding repetitive auto traffic. It is the hope of U.S. Bridge and other contractors that the installation of the SPS bridge will lead to a higher proliferation of lighter weight bridges with quicker installation times. This will also help to address the U.S.’s aging bridge inventory which has reached a critical level and will need to be addressed on a grand scale soon.
Adaptive Materials for the Environment
The slim design of the SPS bridge is advantageous for this area of Ohio, which is known for its steep ravines and low-lying areas. The combination of topographical features leads to changing water levels. The water typically has low-acidic PH levels which is more likely to erode concrete beams and related structures. Therefore, the steel bridge is a terrific alternative. Additionally, certain bridge components were hot-dipped galvanized in an effort to protect from road chemicals that could cause premature corrosion.
