Each of the three bridge repair crews specialize in welding, steel fabrication, concrete finishing and concrete forming. The main quality that might characterize a member of one of these crews is that they are builders and fixers.

The following are examples of typical bridge problems repaired by Heavy Bridge Maintenance Crews:

Rust and holes develop on girders from salt and lack of paint.
Potholes develop from salt corroding reinforcing steel in bridge decks.
Failures in bridge joint armors cause dangerous situations. 
Failures in bridge joint armors cause dangerous situations. 
Fatigue cracks develop as a result of high traffic volumes and poor fatigue details. 


One of the major causes of repair to bridges is accident damage -- over height loads strike the girders on a bridge and cause extremely serious damage. These girders are usually repaired by heat straightening but may require complete replacement. In some cases, trucks can crash into bridge piers or bents – when this happens, the crews will go into overtime – it gets that serious when the highway is closed down (especially an Interstate). This means that the crews have to be available for immediate mobilization to a bridge site with the right tools and equipment to do the job.

Heavy Bridge Maintenance is also involved in product evaluation as it relates to bridges including: joint materials, paints, concrete deck patch material, concrete deck sealing material, epoxy materials, etc.
