U.S. Bridge takes on plenty of unique projects. However, one of our most distinct builds was the bridge along County Road 41 over Moxahala Creek in 2018. Muskingum County Engineering carried out site plans while U.S. Bridge designed, contracted, installed, and fabricated the bridge. This beautiful crossing in Newton Township spans 118 feet, 6 inches and the features of the bridge are what make it stand out amongst the rest.
3D-Modeling the Bridge over Moxahala Creek
Every bridge we build is first modeled in full 3D by our designers to guarantee a perfect shop-and-field-fitting of the steel members. Our bridge builders use Bridge Information Modeling (BrIM) to assign each component a unique name. This then automatically transfers the name and marking to the steel components by using stencil techniques.
In addition to this, BrIM also enables precise fabrication and just-in-time material supplies. This results in optimized solutions for all parties involved in the project and data that may be used for future preventative maintenance.
Exploring the Bridge Elements
When taking a look at the bridge in detail, several features stand out. Most notable is the 45° RF skew angle between the bridge’s longitudinal axis and the centerlines of the bearing, which lie along the abutments. The bridge’s high skew angle is pronounced and allows the Moxahala Creek to flow unobstructed.
Limiting Bridge Movement
Thermal movement can create enormous amounts of internal stress on the components of a bridge. However, using a polymer-modified asphalt expansion joint system (PMAEJS) limits the bridge’s thermal movement. Since there are very few locations where the temperature doesn’t fluctuate, thermal mobility is a factor that must be considered in every part of engineering. The PMAEJS was installed in accordance with ODOT Supplemental Specification 846.
Using Corrugated Steel Floor Planks
One final unique feature of this bridge is the use of corrugated steel floor planks with the addition of shear studs. These studs engage and fasten the concrete fill layer to the driving surface. As a result, the corrugated floor is bolted to the supporting stringer beams through the use of bolted steel clips in a staggered pattern every 9 inches and 18 inches on the side.
Bolted clips are preferred over other steel floor attachment methods, such as welding, because they don’t damage the protective galvanized layer.
Bridges like the one spanning over Moxahala Creek add plenty of complexity to any project. However, as an industry-leading fabricator, it is our mission to provide excellent quality and engineering while keeping your project running smoothly.
Engineering Perfected with U.S. Bridge
With over 80 years of experience building bridges, we know what it takes to get the job done, no matter the challenge. Because of this, it’s our priority to understand each project and perform above and beyond expectations in order to provide each project with the attention and care it deserves.
