Girder Bridges
Girder bridges are one of the most common bridge types and are used as essential components of America’s roadways. While simple in appearance, they require precise engineering and planning to deliver enduring reliability. With the acquisition of Summit Engineering Group, Modjeski and Masters offers not only steel girder designs but also spliced precast concrete girder designs. These specific bridge types include:
U-Girder Bridges
Innovative value engineering solutions were the catalyst for introducing the U-girder concept into the bridge market. Their beginnings can be traced to usage in Colorado bridges promoted by the Colorado Department of Transportation. The structural shape is suitable for both long and short spans. It creates an attractive structure, offers significantly lower fabrication times, reduces the number of joints and bearings, and offers extensive span continuity.
Spliced Bulb Tee Girder Bridges
The spliced precast bulb tee girder/slab system is post-tensioned for continuity and can accommodate longer spans and reduce the amount of substructure. This type of construction has proven a cost-effective alternative to steel plate girders and can be designed to produce a durable structure that is fully compressed at all times under dead loads.
