Signature Stone is an Official Licensed Manufacturer of Velpont™.
Velpont is a modular, precast concrete crossing system designed to accelerate bridge construction and provide highly resilient infrastructure. By utilizing pre-engineered, modular components, Velpont simplifies the entire process from design to installation.
Highway & Road Crossings: Reliable infrastructure for municipal and state transportation networks.
Rural & Private Access Bridges: Cost-effective and durable crossings for private lands, logging routes, and agriculture.
Emergency Crossing Repairs: Rapid-deployment solutions to quickly restore access after washouts or structural failures.
Conservation & Wildlife Underpasses: Ecologically conscious structures designed to facilitate safe animal migration and reduce vehicle collisions.
Substructure: Includes precast abutment blocks, corner blocks, drain blocks, back wall blocks, and footing blocks that anchor the site and resist water pressures.
Superstructure (Planned/Compatible): Includes precast bridge beams, edge beams, and transition curb blocks to form the structural span.
Our Northern Colorado and extended regional market presents unique geographical challenges. Velpont bridges address these directly:
Freeze-Thaw Durability: Manufactured using high-quality wet cast concrete, Velpont components resist the harsh seasonal weather swings and freeze-thaw cycles common in Colorado.
Environmental & Angler Benefits: Velpont’s open-bottom arch and span designs allow streams to remain in their original, natural state. This preserves vital fish habitats and reduces the likelihood of flooding and washouts during severe storm events.
Straightforward Installation: The modular block design does not require specialized bridge-building equipment or highly specialized bridge installation experience, saving time and labor costs for local crews.
As a licensed producer, Signature Stone manufactures and supplies the full suite of Velpont substructure components directly from our facility. We ensure precise quality control, local delivery coordination, and rapid availability for your Northern Colorado, Wyoming, or Nebraska project.
Designed for sites that require a spread footing rather than placing the abutments directly on bedrock or pile foundations. These blocks provide a wide, stable base to evenly distribute the structural load of the bridge and traffic above.
The core of the Velpont substructure. These reinforced, wet cast blocks stack securely using a modular knob-and-groove system to provide both vertical support for the bridge deck and lateral support to retain the earthen approach.
45° and 90° corner blocks allow the abutments to follow irregular stream alignments and natural banks without requiring complex, custom-poured geometry. Integrated drain blocks ensure proper water management to relieve hydrostatic pressure behind the walls.
Back wall blocks are used at the top of the abutment to retain the road base material directly behind the bridge span. Coping blocks provide a clean, finished top edge to the abutment walls, protecting the structure while offering a polished final look.
One of the greatest advantages of the Velpont system is how efficiently it goes into the ground. Because the components are precast and modular, installation doesn’t require specialized bridge-building crews or highly specialized equipment. Local contractors can often install the substructure using standard heavy machinery they already have on site.
To streamline your design and planning process, engineers and contractors can access the comprehensive Velpont Block Library. This resource provides the exact specifications, dimensions, and weights for every modular component in the substructure system.

No. Velpont’s modular, precast design is engineered for straightforward installation. Most projects can be completed by a standard three-to-four-person civil construction crew using typical heavy machinery, like an excavator, without requiring specialized bridge-building experience.
he system is manufactured using high-quality wet cast concrete, which is highly resistant to extreme seasonal weather swings and the destructive freeze-thaw cycles common in Northern Colorado, Wyoming, and Nebraska.
Yes. Velpont components can be configured to create open-bottom arches and spans that leave natural stream beds untouched, preserving fish habitats. The system is also frequently used to build wildlife underpasses to facilitate safe animal migration and reduce vehicle collisions.
Because every crossing is unique, pricing and design specifications depend on your specific site requirements, soil conditions, and load needs. Contact our team at Signature Stone to discuss your project, and we can provide engineering resources, CAD drawings, and accurate local pricing
Yes. Velpont is engineered to support substantial structural loads. It is routinely used for municipal highway crossings, as well as rural and private access bridges that require heavy logging, farming, or commercial equipment access.
By using pre-engineered, precast modular components, Velpont significantly accelerates the construction timeline. It eliminates the delays of forming, pouring, and curing cast-in-place concrete on site, making it an excellent solution for rapid-deployment emergency repairs and tight project schedules.
Yes. The system includes 45-degree and 90-degree corner blocks, alongside integrated drain blocks. This modularity allows the retaining walls and abutments to seamlessly follow irregular stream alignments and natural banks without requiring complex, custom-poured concrete forms.
As your locally licensed manufacturer, Signature Stone produces the substructure components directly at our facility. We coordinate local delivery directly to your job site in Northern Colorado, Wyoming, or Nebraska, ensuring the blocks arrive precisely when your crew is ready to set them.
The system’s foundation, or substructure, utilizes modular precast elements including abutment blocks, corner blocks, drain blocks, back wall blocks, coping blocks, and footing blocks. The superstructure, which forms the span, is planned to include precast concrete edge beams, T-beams, and transition curb blocks.
An open-bottom design allows streams to remain in their natural state, which improves long-term infrastructure resiliency. By preserving natural water flow rather than restricting it through a closed culvert, the system significantly reduces the risk of flooding and washouts during heavy storm events.
Velpont is highly versatile and is commonly deployed for local and state roadway crossings, rural and private access routes, emergency crossing repairs, and conservation group-led initiatives. It is also designed to serve as a wildlife underpass, mimicking natural terrain to maintain habitat connectivity.
The modular bridge system is engineered to accommodate and support crossing spans of up to 75 feet (22.8 meters).
