What are utility crossings?

Utility crossings are installations that route underground utilities beneath roads, railroads, waterways, or other obstacles. They are installed by directional drilling, jack and bore, or open cut methods depending on the crossing geometry and permit requirements.

What permits are required for utility crossings in Oklahoma?

Permits depend on what is being crossed. Highway crossings require ODOT permits. Railroad crossings require a crossing license from the railroad. Waterway crossings may require Army Corps of Engineers Section 404 permits. Trinity manages the permit process for all crossing types.

Oklahoma Utility Crossing Services for Every Obstacle Type

Every utility system encounters obstacles that must be crossed without disturbing the surface above. Roads and highways are the most common obstacle. Railroads are the most complex to permit and the most demanding in terms of installation requirements. Waterways and creeks require environmental permits and precise installation depth control to meet minimum cover requirements. Existing utility corridors require careful bore path design to maintain separation from other underground infrastructure. Trinity Boring Solutions has completed utility crossings of all these obstacle types across Oklahoma, and our experience with each type of crossing informs our approach to every new project.

The choice of crossing method depends on the specific conditions of the crossing: the length, the depth required, the pipe or conduit size, the soil or rock formation along the crossing path, and the requirements of the permitting agency that governs the obstacle being crossed. Trinity evaluates all of these factors during the project planning phase and recommends the most appropriate method for each crossing.

In some cases, the permitting agency specifies the required method, such as an ODOT highway crossing that requires jack-and-bore with steel casing at a major interchange. In other cases, the contractor has flexibility to choose the method, and Trinity chooses based on efficiency, cost, and risk.

For directional bores, Trinity uses the equipment from our 10-rig fleet that is sized appropriately for the crossing diameter and length. Larger crossings require larger rigs with the thrust and torque capacity to complete the reaming passes and the pullback without getting stuck. Smaller crossings use compact rigs that can be set up quickly and completed in a day. The right rig for each crossing is selected during the planning phase, not after the crew arrives on site and discovers the equipment cannot handle the job. That planning discipline is what keeps Trinity’s utility crossing projects on schedule and within budget.

Highway and Road Crossing Permits

Utility crossings of ODOT maintained highways require a highway crossing permit application that includes the crossing location, depth below the road surface, pipe or conduit type, installation method, traffic control plan, and the contractor’s insurance and bonding documentation. Trinity prepares the permit application with all required exhibits and submits it to the appropriate ODOT district office. Lead times for ODOT highway crossing permits typically range from 2 to 8 weeks depending on the crossing complexity and the district’s workload.

City and county road crossings require similar permits from the local road authority. Trinity coordinates with municipal public works departments and county road departments for road crossing permits, providing the same level of application detail required by ODOT and complying with any local conditions imposed by the road authority. After the crossing is complete, Trinity provides the as-built documentation required by the permit close-out conditions and obtains the road authority’s acceptance sign-off. See our road and highway utility work services for the full scope of our work in public right-of-way.

Waterway and Creek Crossings

Utility crossings of waterways in Oklahoma range from small drainage channels to major rivers. The environmental sensitivity of waterway crossings makes them one of the most heavily regulated utility crossing types. Crossings of navigable waterways and regulated tributaries may require Section 404 permits from the Army Corps of Engineers and Section 401 water quality certifications from the Oklahoma Department of Environmental Quality. The permit conditions specify the minimum depth below the streambed, the installation method, and the environmental protection measures required during construction.

Directional boring is the preferred installation method for waterway crossings because it can achieve the required depth below the streambed without any disturbance to the waterway or its banks. Trinity designs waterway crossing bore paths to achieve the minimum depth specified in the Army Corps permit, which is typically 4 to 6 feet below the streambed in navigable waterways.

The bore entry and exit points are set back from the waterway bank to allow for the sweep of the bore path while maintaining the required cover at the center of the crossing. Environmental protection measures at the bore entry and exit points, including secondary containment for drilling fluid, are implemented as required by the permit conditions.

For smaller waterways and drainage channels that do not require Army Corps permits, Trinity designs the crossing bore path to achieve a minimum of 3 to 4 feet below the channel bottom to protect against scour erosion that could expose the pipe. Bore path documentation for waterway crossings includes depth measurements at the channel centerline to confirm the required cover was achieved. Trinity provides this documentation to the project owner and to the permitting agency as required.

Railroad Utility Crossing Licenses

Railroad crossings are the most complex utility crossings to permit because railroad companies have strong authority over any work within their right-of-way. Trinity has experience obtaining crossing licenses from BNSF, Union Pacific, and Oklahoma short-line railroads. The license application must include engineering drawings showing the crossing location, depth below the rail, casing pipe specifications, and the installation method. The railroad’s engineering department reviews the application and may require modifications to the design before approving the crossing.

Railroad crossing licenses typically require a steel casing pipe that is installed through the railroad embankment by jack-and-bore methods. The casing pipe must be designed for H-20 highway loading equivalent to the wheel loads of locomotives passing over the crossing, and the casing must extend beyond the limits of the railroad right-of-way on each side. The carrier pipe runs inside the casing with casing spacers and end seals.

Trinity provides the jack-and-bore service for railroad casing installations, including the setup of the jacking pit and receiving pit on each side of the railroad, the jacking operation, and the installation of the carrier pipe inside the casing. See our railroad utility crossings page for complete detail on this specialized service.

Multi-Utility Crossing Projects

Some utility crossing locations require multiple utilities to cross the same obstacle in close proximity. A highway interchange may require crossings for water, sewer, gas, electrical conduit, and fiber optic conduit all within the same interchange right-of-way. Rather than running multiple separate crossings at the same location, Trinity can design a shared crossing approach where feasible, running a duct bank or bundled conduit system through a single crossing that accommodates multiple utility types.

Multi-utility crossings require careful coordination with all of the utility owners to agree on the crossing approach, the conduit layout within the crossing, and the construction sequence. Trinity facilitates this coordination and provides the technical documentation needed for each utility owner to evaluate the shared crossing design. When shared crossings are not feasible due to utility separation requirements or utility owner preferences, Trinity manages multiple individual crossings at the same location, coordinating the permitting and installation sequencing with ODOT, the railroad, or the Army Corps to minimize the duration of impact at the crossing location.

Utility Crossing Resources and Permitting Agencies

Frequently Asked Questions: Utility Crossings Oklahoma

What is the minimum depth for a utility crossing under an ODOT highway? +

ODOT typically requires a minimum depth of 60 inches (5 feet) below the road surface for utility crossings under state highways. The exact depth requirement is specified in the ODOT crossing permit and may be greater for major highways or at locations where embankment geometry or drainage conditions affect the safe minimum depth. Trinity designs all ODOT crossing bore paths to achieve the required depth with margin to spare.

How long does it take to get an ODOT utility crossing permit? +

ODOT crossing permit lead times vary by district and crossing complexity. Simple crossings at minor highways can be permitted in 2 to 4 weeks. Complex crossings at major interchanges or divided highways may take 6 to 10 weeks. Trinity submits permit applications as early as possible in the project schedule to avoid permit delays that would affect the construction timeline. Rush permit requests are sometimes accommodated by ODOT for emergency or time-critical projects.

Can Trinity cross waterways without an Army Corps permit? +

Some waterway crossings qualify for Nationwide Permit 12 issued by the Army Corps of Engineers, which provides a pre-authorized permit for utility line crossings that meet specific size and impact thresholds. Trinity evaluates each waterway crossing against the Nationwide Permit 12 criteria and processes the appropriate notification if the crossing qualifies. Crossings that do not meet the Nationwide Permit thresholds require an individual Section 404 permit, which has a longer processing time.

What is the difference between directional boring and jack-and-bore for road crossings? +

Directional boring (HDD) steers a drill head through the soil using a curved bore path, allowing entry and exit points to be set back from the road edge. Jack-and-bore pushes a steel casing in a straight line through open cuts on each side of the road. Jack-and-bore requires a straight crossing geometry and produces a steel-cased crossing. HDD produces a smaller footprint, does not require a straight path, and is faster for shorter crossings. The method is selected based on the crossing geometry, permit requirements, and soil conditions.

Does Trinity handle the traffic control for road crossings? +

Yes. Trinity develops and implements traffic control plans for utility crossing work in public right-of-way. The traffic control plan is submitted with the crossing permit application and must be approved by the road authority before work begins. Our traffic control setup complies with OSHA standards and MUTCD requirements. For ODOT highway crossings, the traffic control plan is reviewed and approved by the ODOT district traffic engineer before we mobilize.

How does Trinity manage drilling fluid during a directional bore crossing? +

Drilling fluid (bentonite-based mud) is used to lubricate the bore, cool the drill head, and carry cuttings back to the surface. Trinity carries vacuum recovery tanks at both the entry and exit points of every bore to capture fluid returns. All fluid spoils are disposed of at an approved facility. Secondary containment is placed around the mixing and recovery equipment to prevent any spill from reaching storm drains or waterways. Fluid management compliance is particularly critical for waterway crossings where the permit conditions specify environmental protection requirements.

Can utility crossings be installed in winter in Oklahoma? +

Yes. Oklahoma winters are generally mild enough to allow continuous utility crossing work. Frozen ground conditions, when they occur, can affect the drill head’s ability to steer in shallow formations, and frost can make trench excavation at the entry and exit pits more difficult. Trinity monitors weather conditions and adjusts the drilling fluid mix and equipment configuration for cold weather conditions when necessary. We do not typically suspend crossing operations due to winter weather in Oklahoma.

What size crossings can Trinity complete with their directional drilling fleet? +

Trinity’s fleet handles crossing diameters from 2 inches to 36 inches or larger with steel casing. Crossing lengths range from 50 feet to over 2,000 feet depending on soil conditions and the rig selected for the crossing. The specific crossing capability depends on the combination of bore length, pipe diameter, and soil conditions, which Trinity evaluates during project planning to confirm the appropriate rig selection.

Does Trinity provide as-built records for utility crossings? +

Yes. As-built records for utility crossings include bore path survey data, depth measurements at key points including the center of the crossing, entry and exit point photographs, and bore log data. This documentation is provided to the utility owner, the project engineer, and permitting agencies as required by the permit close-out conditions. As-built records are stored in Trinity’s project archive for future reference if the crossing location must be identified for subsequent utility work.

How does Trinity prevent the bore from hitting existing utilities during a crossing? +

Before every crossing, we confirm all utility locate marks from Okie811 and supplement with hydrovac daylighting at the entry and exit points where existing utilities may be present. The bore path is designed to clear all identified utilities by the required separation margins. During the bore, the drill head position is tracked continuously with locating equipment, and the operator steers to maintain the design path. Any deviation from the design path is corrected immediately. If an unexpected utility is encountered that was not identified in the locates, the bore is stopped and the situation is assessed before continuing.

Why Trinity Boring Solutions Is Oklahoma’s Proven Choice for Utility Crossings

Oklahoma’s underground infrastructure is growing rapidly to meet the demands of population growth, economic development, and the replacement of aging systems that were installed decades ago. Every segment of that infrastructure build requires contractors who bring more than equipment to the job site. It requires operators who understand the engineering behind what they install, project managers who can navigate the regulatory environment without slowing the project, and a safety culture that protects workers, existing utilities, and the public throughout every hour of the work.

Trinity Boring Solutions has built exactly that combination of technical capability, regulatory knowledge, and safety discipline over years of working on some of Oklahoma’s most challenging underground utility projects.

The communities we serve across Oklahoma’s 77 counties depend on the underground infrastructure we help build and maintain. When a rural water district extends its system to serve a new rural subdivision, the families who will live there depend on the quality of the pipe installation to deliver clean, reliable water for decades. When a municipality extends its sewer system to a growing commercial district, the businesses that open there depend on the sewer system to function correctly from day one.

When a gas utility installs new distribution infrastructure in a growing community, the safety of every property served by that system depends on the quality of every joint, every depth measurement, and every valve installation in the distribution system. Trinity takes that responsibility seriously on every project, regardless of scale.

The Trinity Difference: Planning, Precision, and Performance

What separates good utility contractors from great ones is what happens before the equipment hits the ground. Trinity Boring Solutions invests in pre-construction planning on every project because the decisions made in the office before mobilization determine how well the project goes in the field. We review the design documents carefully, identify potential problems, and address them before they become delays or extra costs. We confirm permit requirements and lead times, identify utility conflicts that need resolution, and plan the installation sequence to keep the project moving forward efficiently from start to finish.

In the field, our crews execute the plan with the precision that the design requires. Grade is maintained with laser equipment on every gravity system installation. Bore paths are tracked continuously and corrected immediately when they deviate from the design. Bedding and backfill are placed and compacted in the sequence and to the density specified by the project documents. Safety procedures are followed without exception because a shortcut that saves five minutes is not worth the consequences of a worker injury or a utility strike. That discipline in the field is what produces results that stand up to inspection and perform correctly for the life of the installation.

Performance on Trinity projects is measured not just by completing the work but by the quality of what is left behind. A water main that holds pressure and passes bacteriological testing. A sewer main that maintains grade and passes the mandrel and leakage tests. A directional bore that stays on the designed path and achieves the required depth at every point.

A gas service that holds the pressure test and is accepted by the gas utility’s inspector without exceptions. These outcomes require consistent attention to detail and a refusal to accept substandard work at any stage of the installation. That standard is non-negotiable at Trinity Boring Solutions, and it is the reason clients come back to us for subsequent projects.
