At Radtke Contractors Inc., we handle just about any bridge construction project you need for your commercial or residential property. 


Pedestrian Bridges

One of the most requested bridge building projects we get is the pedestrian bridge - also known as a footbridge. This bridge type is most convenient for pedestrians on foot or bicycle to cross busy roadways, waterways, and other areas. If you own a park, nature reserve, golf course, zoo, or commercial property and you need a pedestrian bridge constructed, give our team a call!

Road Bridges 

Radtke constructs road bridges to allow motor vehicles to safely cross waterways, railroad tracks, another road for motor vehicles, or other areas requiring an overpass. Contact our bridge contractors for a quote on a large, structurally sound road bridge project. We provide replacement road bridges as well as brand new constructions.

Railroad Bridges

Railroad bridges are steel trestles that consist of a series of short and long plate girders. These alternate over a row of box-shaped towers that taper outward from the deck to the ground. If you need a railroad bridge installation or replacement project performed, give our team a call.

Wooden Bridges 

If you need a simple wooden bridge for aesthetic purposes for your park, pond, garden, golf course, etc., we can build you one! This bridge type is common in walking and snowmobile trails, golf courses, and general pedestrian bridges. 

Slab Span Bridges

Slab span bridges are monolithic, flat concrete beams (slabs) with twisted or roughened reinforcing steel rods concentrated in the lower portion and at either end of the slab. Contact the Radtke Contractors team for more information about slab span bridge project details.

​Foundational Pile Driving

We provide foundational pile driving for building solid bridge support from the ground up. Read more information on our foundational pile driving page to see how we can help you. Foundation piling strategies will depend on the type of bridge in question, the condition of the soil, etc.

Pre-Stressed Girders

To minimize road closure as much as possible, we use pre-stressed girders. If you are not already familiar with what a pre-stressed girder is, they are essentially concrete beams that are poured and set prior to the installation of the bridge. We use these to speed up the construction project as much as possible.

Cast-In-Place Structures

Cast-in-place structures is a type of construction technology that involves building construction where slabs and walls are poured on-site. Depending on the specific needs for your bridge building project, we may use cast-in-place structures.

Box Culverts

We construct box culverts typically for a smaller bridge over a creek or a stream. Contact Radtke Contractors for more information about box culverts for your bridge construction.

Steel H-Piling

Steel H-Piling is a structural, square beam that's driven into the soil for deep foundation applications to support large bridges and other structures.

​Wooden Piles

If needed for your bridge construction project, the Radtke bridge builders will construct wooden piles. These are used to build long-lasting foundations for structures on land and in water.

Retaining Walls

When performing a bridge construction, we will discuss the need for retaining walls if applicable. Retaining walls are built laterally supporting soil to avoid spillover, sometimes used for a sidewalk or driveway.
