Our Markets
Nine specialized markets, one self-performing team. Every crew is trained, equipped, and experienced in the market it serves.
Design-build available in every market.
Bring us a problem, not just a plan set. InLine delivers design-build for all aspects of our work — one accountable team from engineering through energization.
Intelligent Transportation Systems (ITS)
Smarter roads move more people, more safely. We build the field infrastructure and communications networks that let agencies see, manage, and respond to traffic in real time.
- CCTV cameras & video detection systems
- Dynamic message signs & traveler information
- Fiber interconnect & ITS communication networks
- Ramp metering, sensors & connected-vehicle infrastructure
- Traffic management center integration & support
Roadway Lighting
Safe roads start with well-lit roads. We build and maintain lighting systems along highways, interchanges, and city corridors, with maintenance contracts available as requested.
- Conventional & high-mast highway lighting
- Interchange & corridor lighting systems
- LED conversion & energy-efficiency programs
- Underground distribution, foundations & service points
- Maintenance contracts, knockdown response & repairs
Traffic Signals
From single-intersection rebuilds to corridor-wide modernization, we deliver complete traffic signal construction for DOTs, counties, and municipalities — and we hold ongoing maintenance contracts, providing maintenance as requested.
- New signal installations, upgrades & rebuilds
- Mast arms, poles, foundations & span wire
- Vehicle detection, cameras & preemption systems
- ITS interconnect, fiber & communication networks
- Maintenance contracts, on-call service & emergency response
Bridge Electrical & Lighting
Electrical work on structures demands precision and coordination. We install lighting and electrical systems on bridges, overpasses, and elevated roadways.
- Roadway & pedestrian lighting on structures
- Aviation lighting & navigation lighting systems
- Structure-mounted conduit & junction systems
- Aesthetic & architectural lighting packages
- Coordination with bridge GCs & agencies

Data Center Site Infrastructure
Mission-critical facilities start with mission-critical site work. We deliver the underground electrical backbone for data center campuses on aggressive schedules.
- Duct bank design support & construction
- Site power distribution & medium-voltage raceway
- Underground utility & telecommunication networks
- Site lighting & security infrastructure
- Schedule-driven crews for fast-track builds
Fiber & Wireless Networks
We've designed, constructed, owned, and operated large fiber and wireless networks — experience few contractors can claim. Today our focus is construction, and every network we build reflects what we learned running our own: build it clean, document it completely, and make it easy to operate for decades.
- Long-haul, metro & middle-mile OSP construction
- Directional drilling, trenching & duct systems
- Aerial plant & make-ready construction
- Fiber splicing, testing & end-to-end certification
- Tower, small cell & DAS construction
- Wireless backhaul & network integration
- Operator-grade as-builts, documentation & turn-up support
Ballfields & Parking Lots
From Friday night lights to fully powered parking facilities, we deliver complete site lighting and electrical for parks, schools, athletic complexes, and commercial owners.
- Sports field lighting systems & controls
- Lot & garage lighting systems
- Concrete & steel poles, bases & foundations
- EV-charging-ready electrical infrastructure
- Electrical services, distribution & scoreboard power
- Maintenance & repair programs
Roadway Signs
The biggest signs on the highway don't hang themselves. We build complete overhead sign structures — from foundations to panels — over live traffic.
- Overhead sign bridges & truss structures
- Cantilever & butterfly sign structures
- Drilled shaft foundations & anchor assemblies
- Crane erection over live traffic
- Sign panels, lighting & DMS structure integration
Airports
Airfield electrical work carries zero tolerance for error. Our crews build both the electrical and the communications backbone of the modern airfield — lighting, signage, and fiber networks — to FAA standards on active airfields, safely and on schedule.
- Runway & taxiway edge lighting systems
- Airfield guidance signage & circuits
- Electrical vaults & constant-current regulators
- Airfield communications, fiber backbone & duct systems
- Apron & landside lighting
- FAA AC 150/5370 & phased-construction experience
