Utility Crossings Oklahoma. Trenchless Underground Crossings Contractor.
Trinity Boring Solutions installs utility crossings under roads, highways, waterways, and paved surfaces throughout Oklahoma using horizontal directional drilling, pneumatic boring, and auger boring. No pavement cutting, no road closures, no restoration headaches.
What Are Utility Crossings and When Are They Needed?
A utility crossing is the installation of a pipe, conduit, or cable beneath an obstruction such as a road, highway, railway, waterway, or paved surface, connecting utility infrastructure on one side to the other without disturbing the surface above. Utility crossings are one of the most common applications for trenchless construction methods, and they arise on virtually every site development project, utility extension, and infrastructure upgrade that involves bringing utilities across an existing surface feature.
In Oklahoma, utility crossings occur in every project context. New residential subdivisions need water, sewer, gas, and electric crossings under collector streets. Commercial developments cross state highways to connect to municipal utilities. Agricultural operations bore under county roads for irrigation mainlines. Industrial facilities cross rail spurs for process utility connections. Municipal utilities expand distribution networks by crossing existing arterial roadways without disrupting traffic. Each of these applications has the same basic requirement: get the utility from point A to point B under an obstacle, cleanly and efficiently.
The alternative to trenchless crossing is open cut, which involves cutting through the road, installing the utility, and restoring the pavement. For minor crossings under private driveways, open cut may be acceptable. But for crossings under state highways, county roads, and arterial streets, open cut typically requires an encroachment permit, significant traffic control measures, and expensive pavement restoration including concrete saw cutting, asphalt removal, and full-depth pavement restoration with compaction testing. The cost and disruption of open cut under major roadways makes trenchless boring the preferred and often the only permitted method.
Trinity Boring Solutions provides utility crossing services using three primary methods: horizontal directional drilling for crossings requiring steering capability, curved paths, or larger diameter pipes; pneumatic boring for straight, shorter crossings in cohesive soil; and auger boring for steel casing crossings under roads and railways. Each method has specific applications, soil requirements, and diameter capabilities, and we select the right method for each crossing based on these factors.
Our utility crossing services work in concert with our open cut trenching on combined projects. When a project involves trench runs with multiple crossings, we perform all the trenching and all the crossings as a single scope, providing coordinated project management and a single point of contact for the complete underground scope. For more information on our directional drilling capability, see our directional drilling contractor in Oklahoma page. For the trench portions of combined projects, our trenching services are available throughout the state.
Utility Crossing Methods: Directional Drilling, Pneumatic Boring, and Auger Boring
Understanding the differences between crossing methods helps you select the right approach for your project and budget.
- Horizontal directional drilling (HDD). HDD uses a steerable drill head to navigate a curved bore path from the entry point to the exit point. A pilot bore is drilled first along the designed path, then enlarged in one or more reaming passes to the diameter needed to pull back the product pipe or conduit. HDD can cross under rivers and waterways, navigate around underground obstacles, and install pipe on curved paths that pneumatic or auger boring cannot achieve. Suitable for crossing diameters from 1 inch to 12 inches and larger for special applications.
- Pneumatic boring. A pneumatic mole is driven through the soil in a straight line using percussion energy from compressed air. This method is fast and economical for short, straight crossings in cohesive soil where precise steering is not required. Suitable for crossings from 10 to 60 feet in length, diameters from 2 to 6 inches typically. Less suitable in loose sand or gravelly soils that provide insufficient cohesion to maintain the bore hole.
- Auger boring. A rotating auger inside a steel casing is advanced through the soil, removing spoil through the casing as it advances. Used for steel casing crossings under roads and railways where a rigid structural casing is required to support the overlying soil and pavement. After casing installation, the carrier pipe is installed inside the casing with annular space filled per the applicable standard. Common for natural gas and petroleum pipeline crossings and for railway crossings where casing requirements are mandated by the surface owner.
Each method has specific soil condition requirements. We evaluate soil boring data when available, review available ODOT or county road construction records, and apply field experience from similar projects in the same area when selecting methods and designing crossing parameters.

ODOT Utility Accommodation Permits for Oklahoma Highway Crossings
All utility installations within Oklahoma state highway right-of-way require a utility accommodation permit from the Oklahoma Department of Transportation. The ODOT Utility Accommodation Policy specifies permitted crossing methods, required bore depths below pavement, casing requirements for certain utility types, and inspector requirements for crossings on the state highway system. Trinity Boring Solutions is ODOT approved, meaning we are pre-qualified to perform utility crossings under ODOT permits. We manage the permit application process and ensure our crossing meets all ODOT specification requirements. For crossings of county roads, we work with the applicable county road authority for their specific permit requirements. All utility crossing work requires prior notification through Oklahoma 811.

Frequently Asked Questions: Utility Crossings in Oklahoma
What is the minimum depth for a utility crossing under a state highway in Oklahoma?
ODOT requires minimum depths below pavement for utility crossings that vary by utility type and road classification. Generally, utilities must cross at sufficient depth to avoid interference with roadway structure and future maintenance operations. ODOT’s Utility Accommodation Policy specifies these requirements. Gas and petroleum pipelines typically require steel casing under major highways. We review ODOT requirements for each specific highway crossing and design the bore to comply with the applicable depth and casing requirements.
How long does a typical utility road crossing take?
A simple directional drill crossing under a two-lane county road for a 2-inch conduit run can be completed in one day including setup, pilot bore, reaming, and product pullback. Larger crossings under multi-lane highways with 4-inch to 8-inch product pipe may take two to three days. Difficult soil conditions, utility conflicts during drilling, or water body crossings requiring environmental permit coordination add time to the schedule. We provide realistic time estimates based on the specific crossing conditions.
Can you install multiple conduits in a single bore crossing?
Yes. Multiple smaller conduits can be bundled together and pulled back through a single larger bore. For example, a 6-inch bore can accommodate three or four 1-1/2-inch conduits bundled together. This is an efficient approach when multiple utilities need to cross the same obstruction at the same location. We evaluate bundled conduit configurations during project planning.
What happens if you hit rock during a highway crossing bore?
Encountering rock during a crossing bore requires different drill bits and potentially different drilling fluid formulations. We carry rock-capable tooling for HDD crossings and can transition to rock boring procedures when rock is encountered. If rock is anticipated based on regional geology or available boring data, we plan for rock tooling from the start and factor the additional time and wear cost into the project estimate. Rock crossings are slower than soil crossings.
What is the maximum diameter pipe you can install with directional drilling?
Our equipment fleet handles crossings from 1-inch conduit through 12-inch diameter pipe for typical highway crossings. Larger diameter crossings for water mains and sewer force mains can be accomplished with larger HDD rigs. For a specific diameter requirement, contact us to confirm which rig and method are appropriate for your application.
Can you cross under a river or creek with directional drilling?
Yes. HDD water body crossings are a common application. The drill path enters on one bank at sufficient depth to clear the waterway and any scour below the channel bottom, traverses beneath the waterbody, and exits on the opposite bank. Environmental permits may be required for water body crossings under Clean Water Act Section 404 and Oklahoma Water Resources Board regulations. We advise on applicable permit requirements and work within the conditions of any required permits.
Do you need to be on both sides of the road for a directional drill crossing?
Directional drilling requires an entry pit on the drill rig side and an exit pit or area on the receiving side. The entry pit is typically 4 to 6 feet deep and several feet long to accommodate the drill string angle of entry. The exit area needs space for the product pipe to be staged for pullback. Access to both sides of the crossing is required. We evaluate access requirements during project planning and discuss any access challenges with you before mobilization.
How do you prevent surface heaving or settlement during crossings?
Surface heaving or settlement can occur if drilling fluid pressure is not properly managed or if the bore is too shallow. We design bore paths with adequate depth, manage drilling fluid returns carefully, and monitor the ground surface during boring operations. For crossings in sensitive areas such as near foundations or in areas with existing surface improvements, we take additional precautions and can install monitoring points if required.
Do you provide ODOT permit management for highway crossings?
Yes. As an ODOT-approved contractor, we are familiar with the ODOT utility accommodation permit process and can manage the permit application on behalf of our clients. We prepare the required permit documents, coordinate with the ODOT district office, and ensure our work meets all permit conditions. Permit processing time varies by district and project complexity; we factor permit timelines into project scheduling.
