Maintenance

Assisting in maintaining a safe, efficient, and aesthetically pleasing highway system by providing leadership, expertise, and support.

Heavy Bridge Maintenance

Heavy Bridge Maintenance (HBM) is tasked with inspecting and maintaining approximately 60 of the largest and more unique bridges in Arkansas with a asset value of 1.5 billion USD. HBM is comprised of 6 bridge specialty crews, 3 bridge inspections teams, and engineering managing support.

Select on the topics below to learn more about the important work involved in maintaining and preserving Arkansas’s Bridges for the future:

Heavy Bridge Management Responsibilities

-State Heavy Bridge Maintenance Engineer who is responsible for the supervision of the Heavy Bridge Maintenance section. The State HBM Engineer is the State-wide Bridge Inspection Program Manager who oversees all operations of the State’s Bridge Inspection Program. 

-Staff Heavy Bridge Maintenance Engineer who is responsible for bridge repair design/details, oversight of 3 HBM repair crews, a bridge building crew, a polymer overlay crew, a paint crew and the Request for Proposals to hire Engineering firms to perform Underwater Bridge inspections.

-Senior Heavy Bridge Maintenance Engineer who is responsible for the oversight of the 3 HBM State Wide Inspection Teams as well as the QA/QC bridge inspection process, and maintenance contract development such as bridge paint contracts.

-Heavy Bridge Maintenance Engineer who is responsible for analyzing and recommending solutions to bridge maintenance problems, work with inspection teams and help to improve the overall process, and help to manage the Salvaged Bridge Material Program.

– Bridge Management Section Head is responsible for maintaining all aspects of the databases used within the bridge management program, assisting bridge inspection personnel in proper data collection, and developing priorities for optimum bridge management within the constraints of available funds.

– Bridge Management Assistant Section Head is responsible for analyzing priorities for bridge replacement or improvements, performing queries and reports from databases within the Bridge Management Program, and assist the Section Head in all of their duties.

– Heavy Bridge Maintenance Superintendent who coordinates all the crew activities and assures that the crews have the right tools and equipment to do the job. The Superintendent is also tasked with cost accounting for bridge damage to assure reimbursement from the respective insurance companies.

– Three Bridge Repair Crews with one supervisor and five crew members each, one Paint Crew with one Crew Leader and three crew members and one Bridge Polymer Overlay preservation crew with one Crew Leader and three crew members.

– Three State Wide Inspection Teams, which consists of a Bridge Inspector and an Assistant Bridge Inspector.

Heavy Bridge Maintenance Repair Crews

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.  
– 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 can 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. 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.

Heavy Bridge Maintenance Paint Crews

The paint crew specializes in painting Interstate highway bridges. A power washer is used to clean the existing paint surface. Then an overcoat of Calcium Sulfonate paint is applied. By cleaning and painting steel members of the bridge superstructure, corrosion to the members is greatly reduced. This ultimately extends the life of superstructure members, thus extending the life of the Arkansas Bridge.

Heavy Bridge Maintenance Polymer Crew

The Polymer Crew specializes in overlaying bridge decks that are in relatively good condition. The purpose of a polymer overlay is to seal cracks in the deck to prevent water and chlorides from reaching the reinforcing steel allowing for corrosion and deck deterioration. This ultimately gives new life and extends the life of a bridge deck which in turn leads to a better overall structure for the State of Arkansas.

The crew performs this work by cleaning and shot blasting the existing deck surface to prepare the area for good adhesion. The crew will then apply a two part epoxy to the deck followed by covering the epoxy with aggregate. This gives the deck a protective coating that will preserve the deck condition for many years.

Heavy Bridge Maintenance Bridge Building Crew

Heavy Bridge Maintenance’s newest crew will target culverts and small bridges where existing infrastructure is of poor condition or closed. The bridge building crew (backed by engineering support) will be able to cut cost and time associated with traditional bridge replacement contract jobs in order to reopen or keep open State Owned routes. The new crew will be making big impacts in the state in 2021.

Heavy Bridge Maintenance Bridge Inspection

NBIS Bridge Inspection Program Oversight

The bridge inspection program is essential to ensure the safety of our bridges. The primary purpose of the inspection program is to ensure safety to traveling public, however the data produced by the inspections serves multiple functions for the Department.  The data helps prioritize bridge rehabilitation or replacement projects, budget planning, routing over height or overweight permit loads, and a work-priority list for Bridge Maintenance Repair Crews.

Statewide Bridge Inspectors

Heavy Bridge is responsible for inspecting more than 60 of the largest bridges in the state in accordance with the National Bridge Inspection Standards – more than half these bridges require inspection every year.

An inspection of one of these bridges can take from one to three weeks and requires such specialized equipment as an Ultrasonic Flaw Detector to inspect fracture critical bridge elements and an Aspen Aerial A75 Bridge Inspection Unit to reach over the side and 75’ under bridges.

Heavy Bridge is also responsible for Quality Control (QC) and Quality Assurance (QA) of the Arkansas Bridge Inspection Program. These measures are in place to make sure all bridge inspections are uniform throughout the 10 Districts within the state.

Heavy Bridge Maintenance Other Duties

Peel Ferry

Heavy Bridge Maintenance is Liaison to District 9 relating to the Peel Ferry on Bull Shoals Lake. Heavy Bridge Maintenance helps assist the Coast Guard in inspecting and maintaining the Ferry and dry dock area.

Assist with District Bridge Repairs

When a bridge is involved in a serious accident or serious problems are found, Heavy Bridge is called upon to make an evaluation of the damage and recommend a course of action. Heavy Bridge Maintenance Crews assist the District Bridge Crews with repairs as needed.
