Directory: Local Contractors and Vendors for Highway Expansion Projects in Georgia

Need verified contacts fast? A curated directory for businesses chasing contracts on Georgia’s $1.8B I‑75 expansion

If you’re a small business, specialty subcontractor or supplier frustrated by scattered contact info, inconsistent listings, and missed bid alerts — this directory is built for you. The I‑75 expansion proposal announced in January 2026 has already accelerated procurement activity across contractors, traffic engineers, materials suppliers and permitting specialists. To win work you need verified partners, clear entry steps and a practical playbook — all in one place.

The bottom line up front (inverted pyramid)

Georgia’s Governor announced a $1.8 billion plan in January 2026 to add toll express lanes on I‑75 through Henry and Clayton counties. That makes now the highest-opportunity window for firms that can quickly meet GDOT and prime-contractor procurement rules, DBE requirements, bonding and specialized technical needs (traffic modeling, ITS, tolling systems, environmental permitting).

"Georgia has to keep building highways to promote economic growth… When it comes to traffic congestion, we can’t let our competitors have the upper hand." — Gov. Brian Kemp, Jan 16, 2026 (Insurance Journal)

Who this directory serves

• Small businesses seeking subcontracting opportunities (concrete crews, paving, drainage, signalization)
• Materials suppliers (aggregates, asphalt, precast, geotextiles)
• Traffic engineers and ITS integrators aiming for design or systems work
• Permit specialists and environmental consultants who streamline approvals for primes
• Procurement officers and prime contractors building vetted vendor lists

How to use this directory (quick guide)

1. Scan category headings to find firms or regulators by role (prime contractors, suppliers, consultants, permit offices).
2. Note procurement tips alongside each entry — those are actionable steps to qualify or get invited to bid.
3. Prioritize prequalification — register on GDOT and federal portals (SAM.gov), and get DBE/SBE status if eligible.
4. Reach out early for teaming agreements. Subcontracting on highways often begins in the design or early procurement phases.

Directory: Construction firms (primes & heavy highway specialists)

These firms are active in Georgia highways and heavy civil work. They frequently lead GDOT bids, manage large crews, and subcontract specialty trades.

Brasfield & Gorrie — Southeast heavy civil and roadway work

Why consider them: Strong regional track record on complex interchanges and multi‑lane projects. Common prime for GDOT work.

Procurement tip: Pursue early outreach to their preconstruction or small business liaison to be considered for early subcontract scopes (erosion control, concrete paving).

C.W. Matthews Contracting Company — Georgia-based heavy highway specialist

Why consider them: Local heavy/highway focus, experienced with GDOT specifications and express‑lane projects.

Procurement tip: Demonstrate experience with AASHTO-compliant asphalt mixes and civil grading, and provide recent references and bond capacity documentation.

Procurement tip: Demonstrate past performance on tolled corridor designs and integration experience with regional toll authorities.

WSP / Jacobs — systems engineering for ITS and complex interchange geometry

Why consider them: Large multidisciplinary teams that handle systems and civil design concurrently.

Procurement tip: Pitch integrated teams (traffic + ITS + structural) to reduce prime coordination risk.

Directory: Permit specialists, environmental & regulatory contacts

Navigating federal, state and local approvals will be a major schedule driver. These contacts and agencies are essential.

Georgia Department of Transportation (GDOT) — procurement & design standards

Why consider them: GDOT publishes design criteria, bidding calendars and prequalification requirements for state highway work.

Procurement tip: Monitor GDOT bid boards and register for vendor alerts. Ensure prequalification and DBE contact information is current.

State Road and Tollway Authority (SRTA) / tolling authorities

Why consider them: If the express lanes are tolled, SRTA or similar entities will coordinate operations, toll policy and system procurement.

Procurement tip: For tolling equipment and back‑office services, prepare evidence of PCI‑compliance, cybersecurity policies, and payment reconciliation experience.

Georgia Environmental Protection Division (EPD)

Why consider them: EPD oversees state environmental permitting for stormwater, wetlands impacts and air/noise considerations.

Procurement tip: Early wetland delineation and permitting reduces schedule risk. Firms that pre‑estimate mitigation obligations are easier to shortlist.

U.S. Army Corps of Engineers — Savannah District

Why consider them: Federal permits for navigable waters and wetland impacts if the project crosses jurisdictional waters.

Procurement tip: Coordinate Joint Permit applications early and include mitigation sequencing in proposals.

Specialty subcontractor categories to target

• Temporary traffic control and MOT (Maintenance of Traffic) — high demand during staged builds.
• ITS integrators and fiber installers — toll lanes require detection, cameras, and comms.
• Bridge and retaining wall contractors — for interchange ramps and structure widening.
• Drainage & erosion control — sediment BMPs and SWPPP management.
• Small DBE concrete crews and guardrail installers — often the easiest path to enter prime subcontract scopes.

Procurement & bid-winning playbook — action steps you can implement today

1. Register and prequalify: SAM.gov (federal), GDOT vendor portal, and state DBE directories. Have your UEI number, insurance certificates and bonding letter ready.
2. Create a 1‑page capabilities statement: Tailor for highway work; include NAICS codes, core equipment, safety stats (EMR), and references.
3. Build teaming letters: Reach primes with explicit proposals (scope, price basis, timeline) rather than generic intros.
4. Demonstrate compliance readiness: Show familiarity with AASHTO specs, GDOT special provisions, and Davis‑Bacon (if applicable).
5. Offer value‑adds: Propose ways to shorten schedule (night work plans, rapid curing mixes), reduce risk (QA protocols), or lower lifecycle costs (materials with lower embodied carbon).

2026 trends that matter to bidders (late 2025 → early 2026 context)

• Increased toll-lane builds and P3 appetite: State proposals in late 2025 and early 2026 show a stronger push for tolled express lanes — primes with tolling and operations expertise will be prioritized.
• Digital procurement & e‑bidding: More DOTs and primes use cloud bid platforms and digital prequalification — keep documentation digital and searchable.
• Carbon and material traceability: Buyers ask for embodied carbon statements and recycled content; suppliers with EPDs or low‑carbon mixes gain advantage.
• Supply chain stabilization post‑2024 volatility: Material price volatility eased through 2025, but logistical discipline and confirmed delivery schedules remain differentiators.
• Adoption of BIM and digital twins: For large corridors, owners increasingly expect deliverables in models — offer BIM-capable staff or partnerships.

Practical checklist before you bid

• Active SAM.gov and GDOT vendor registration
• Current bonding letter for required limits
• Insurance (GL, Auto, Workers’ Comp) with endorsements required by primes
• DBE/SBE/MBE certification documentation if applicable
• Safety plan and recent EMR record
• Project-specific equipment list and personnel CVs

Illustrative case study (practical example)

Scenario: A small paving subcontractor wants a piece of the I‑75 express lanes in 2026.

Action: They registered on GDOT and SAM, obtained a DBE letter, created a one‑page capabilities statement with recent paving references, and approached two primes with a proposal for night paving and accelerated lane reopen plans. They included a bonding letter and an equipment lease agreement to demonstrate capacity.

Outcome: The prime added them to the shortlist for MOT and paving packages because the small firm reduced the prime’s schedule risk and met the DBE target.

Key takeaway: A concise package that reduces prime risk wins more often than low price alone.

Advanced strategies — stand out in 2026

• Offer digital deliverables: Provide 3D models or BIM-ready design assistance at no extra cost during shortlists.
• Quantify schedule recovery: Use production-rate charts to show how your crew reduces lane closure days.
• Propose sustainability credits: If you supply recycled asphalt or low‑carbon concrete, document carbon reductions and lifecycle benefits.
• Bundle services: Offer combined MOT + paving + striping packages to reduce coordination burden for primes.
• Leverage local relationships: Demonstrate county permitting familiarity (Henry & Clayton counties) and local staging solutions.
