Re-Routing the Juice: Why Utility Relocation Is Critical to Modern Roadway Projects
By Matt George
Most roadway improvement projects are judged by what the public can see: wider roads, new intersections, improved traffic flow, safer crossings, and better access. Yet some of the most critical work occurs long before paving begins and often remains invisible after construction is complete. While utility relocations may appear straightforward, they are frequently among the most complex aspects of a transportation project. Existing utility congestion, changing right-of-way boundaries, clearance requirements, environmental constraints, and the need to maintain system reliability all influence the final design.
Overhead and underground utilities – power, telecommunications, gas, water, etc. – must move out of the way for the expanding roadway footprint. Electric utilities must plan for and design a multitude of electric line relocation projects: converting from open ditch to curb-and-gutter, intersection widenings, bridge rehabilitation or bridge improvement projects, or interstate and highway interchange improvements. What’s more, is that it must all be done while maintaining continuous service to the public.
More Infrastructure, Less Space
Decades ago, a typical transportation corridor may have contained only a few utility systems. Today, roadway improvements usually require unique utility relocation design approaches, since no two projects are identical. What once was a handful of utility systems has turned into an increasingly complex network of electric distribution infrastructure, transmission facilities, telecommunications networks, fiber optic systems, traffic signal infrastructure, water lines, sanitary sewer systems, and stormwater facilities.
Additionally, rights-of-way are becoming more congested and increasingly limited with the continued expansion of telecommunications networks in main corridors or metropolitan areas. Utility owners and transportation agencies are being asked to deliver more infrastructure within the same corridor while maintaining safety, reliability, and access to the public. As a result, utility relocation projects require a level of coordination and planning that extends well beyond simply moving poles or underground facilities. Successful projects often begin years before construction, allowing stakeholders to evaluate alternatives, secure necessary rights-of-way, coordinate with adjacent utilities, and identify solutions that support both current needs and future growth.
The “Simple” Relocation That Wasn’t
A roadway improvement project along State Highway 67 outside of Bixby, Oklahoma demonstrates how utility relocations often involve far more than simply moving facilities from one side of a corridor to the other. What initially appeared to be a straightforward utility conflict quickly became more complex as designers encountered limited-access roadway restrictions, telecommunications infrastructure conflicts, mature vegetation, and constrained opportunities for new pole placement. Multiple design alternatives were evaluated, including both overhead and underground solutions, each presenting its own advantages and challenges.
Ultimately, the selected approach required balancing constructability, operational reliability, long-term maintenance considerations, and impacts on surrounding infrastructure. The project serves as a reminder that utility relocation is rarely a one-dimensional exercise.
The lesson: successful utility relocations require project teams to balance operational, environmental, regulatory, and long-term maintenance considerations simultaneously, and the best solution is not always the most obvious one.
The Interstate Crossing
Interstate crossings present an entirely different set of challenges than a typical roadway widening project. In addition to accommodating future transportation improvements, designers must protect both the integrity of the roadway system and the reliability of the electric grid. For one relocation effort in Love County, Oklahoma, utility designers implemented extensive underground infrastructure, including long directional bores, duct bank systems, and protective casing beneath the interstate. These solutions allowed electrical service to cross the transportation corridor while minimizing impacts to traffic operations and preserving roadway performance. Projects like these highlight the level of planning and engineering that often takes place behind the scenes. What drivers experience as a seamless transportation corridor is frequently supported by carefully designed utility systems built to serve both present-day needs and future growth.
The lesson: what happens beneath the roadway is often just as important as the improvements visible above it, and successful infrastructure projects depend on thoughtful coordination between the systems that keep communities moving and connected.
Why Standards Matter
While every utility relocation project presents unique challenges, consistency remains important. Maintaining known and accepted construction standards is paramount as the individuals tasked with constructing, operating, and maintaining electric infrastructure become accustomed to working on and around these structures. The more the construction varies from the standard, the more these personnel become decreasing familiar with constructability and operability, and the safety risk and exposure almost certainly increases.
As we strive for success on these projects, they must strike a balance between innovation and practicality, developing creative solutions while maintaining the consistency necessary for safe and reliable operation over the life of the asset.
Flexibility By Design
Complexities aside, the flexibility of the electric distribution and transmission systems provide unique configurations to offer the continuity of electric service while accommodating the increased footprint of the adjacent roadways. With overhead distribution systems, the options for customized configurations and alignments can seem almost limitless, with multiple choices in pole material, conductor types, anchoring and guy-wire configurations, and overhead-to-underground transitions. This flexibility enables project teams to adapt to site-specific constraints while continuing to deliver safe and reliable electric service.
Proactive Conversations, Better Outcomes
While much of this work happens behind the scenes, its impact is often visible long after construction is complete. As large metropolitan centers continue to grow and average daily traffic counts and power demands increase, a synchronous relationship between the transportation systems and power infrastructure will have to be forefront to be ready for the adaptive changes required in the future. The most successful projects will recognize utility coordination not as a construction phase activity, but as a planning phase priority.
One lesson I’ve seen reinforced throughout my career is this: early coordination between transportation agencies, municipalities, utilities, and design teams helps reduce risk, improve project schedules, and create infrastructure corridors capable of supporting future growth.
