Two major U.S. highway corridors entered active construction in spring 2026 — one in the heart of Central Florida's tourist economy, the other in the mountain city of Asheville, North Carolina. Together they represent more than $2.3 billion in combined investment and reflect a pattern playing out across the country: IIJA-funded and state-backed corridor programs finally reaching the construction phase after years of planning, environmental review, and right-of-way acquisition.

Florida: Moving I-4 Forward Adds a $582 Million Piece

Lane Construction Corporation, a U.S. subsidiary of Italy's Webuild Group, was awarded a $582 million modified phased design-build contract in April 2026 for "Moving I-4 Forward – Project 2," according to Equipment World. The contract covers a 3.1-mile stretch of Interstate 4 in Central Florida, targeting the heavily congested interchange with State Road 429 — a corridor that runs adjacent to some of the world's highest-volume theme parks and has been identified as one of the state's worst traffic bottlenecks.

Under the contract, Lane will construct four general-purpose lanes and two tolled express lanes in each direction, add direct connectors to eliminate complex weaving between I-4 and SR 429, widen Old Lake Wilson Road with dedicated sidewalks and bicycle lanes, and reconfigure the SR 429 interchange with new express lane bridges. The median will also be configured to accommodate a potential future rail corridor — an explicit acknowledgment that the Florida Department of Transportation is designing the infrastructure to support transit options decades from now. According to Orlando-area real estate tracking, construction is expected to start in summer 2026 and last approximately 4.5 years.

This contract is the second major award Lane has received on the I-4 corridor in 2026. Just two months earlier, Lane was selected for a $643 million contract to reconstruct the Westshore Interchange — the largest FDOT project in the Tampa Bay area — as part of the same broader Moving Florida Forward initiative. Lane currently has 11 active projects in Florida and maintains four construction sites within 50 miles of the new I-4/SR 429 segment. The combined value of its two 2026 I-4 corridor awards exceeds $1.2 billion.

The overarching Moving I-4 Forward program is part of Florida's statewide Moving Florida Forward Infrastructure Initiative, which pulled $4 billion from general revenue surplus and pairs it with leveraged financing and accelerated contracting tools to advance approximately 20 priority transportation projects. The full "Beyond the Ultimate" I-4 program is targeted for completion by summer 2031 and will ultimately add express lanes across roughly 40 miles of I-4 between Polk and Orange counties.

North Carolina: Asheville's I-26 Connector Finally Begins

In western North Carolina, NCDOT broke ground on April 23, 2026 on the Interstate 26 Connector in Asheville — one of the most expensive transportation projects in state history at an estimated cost of $1.8 billion. According to the official NCDOT press release, the project will create a continuous interstate connection between I-26 south of Asheville and U.S. 19/23/70 north of the city — linking the mountains of western North Carolina to the Port of Charleston, South Carolina, for the first time as a fully connected interstate corridor.

The project will include new and upgraded interchanges, bridge construction, multi-use paths, and enhanced pedestrian and bicycle connections. Construction is now underway on the project's north and south sections, with the full project expected to be complete in late 2031. The effort has been funded with a combination of state and federal dollars.

"This project has been a long time coming," said NCDOT Secretary Daniel Johnson at the groundbreaking. "The I-26 Connector reflects years of planning, collaboration, and community input. When complete, it will improve how people and goods move through this corridor while better connecting Asheville's communities and supporting future growth."

The project's complexity was acknowledged directly by the agency. The most expensive sections — Sections B and D — drew a $1.15 billion contract award in 2024, up significantly from the originally projected $915.8 million. Preliminary work alone has already totaled roughly $100 million, according to local reporting. Division 13 Construction Engineer Nathan Moneyham noted: "This project goes beyond moving vehicles. It will improve daily travel for drivers, pedestrians and cyclists by creating a more connected and accessible transportation network throughout the corridor."

Why These Projects Matter to Construction Professionals

Both projects are instructive case studies in how major highway construction is playing out in 2026. The FDOT's I-4 program demonstrates that states with strong fiscal positions and political will can move multiple billion-dollar design-build contracts simultaneously on a single corridor — creating sustained multi-year workloads for the construction firms that position early. Lane Construction's ability to capture two I-4 contracts totaling over $1.2 billion in a single year reflects the competitive advantage of firms that maintain continuous presence in a market.

The I-26 Connector illustrates the opposite dynamic that also dominates the landscape: a project that took decades to fund, plan, and permit but that is now entering a sustained five-year construction program. Cost escalation from original estimates to awarded contracts — from $915.8 million to $1.15 billion for Sections B and D alone — reflects what has happened to heavy civil construction costs since the project was first programmed. Owners, program managers, and contractors on long-gestating projects should expect similar escalation patterns on projects that were designed in earlier cost environments.

For subcontractors and suppliers, both projects represent multi-year pipelines of bridge construction, earthwork, paving, drainage, and traffic systems work in high-growth corridors. The I-4 corridor in Osceola County and the western North Carolina mountain environment each present distinct constructability challenges — tight urban geometry in Florida, terrain and stream crossings in Asheville — that reward specialty firms with regional expertise.

What to Watch

• FDOT's Moving I-4 Forward program has additional phases still in design or procurement; contractors should monitor FDOT District 5 procurement activity through 2026 and 2027.
• The I-26 Connector's Sections B and D represent the most complex civil engineering challenges in the project; watch for updates on sequencing, traffic management phases, and any scope or schedule adjustments as construction advances into mountainous terrain.
• Both projects carry significant ROW and utility relocation components that will drive subcontract activity in the first 12 to 18 months.

Bottom Line

Bottom line:

The FDOT's $582 million I-4 award and NCDOT's $1.8 billion I-26 Connector groundbreaking signal that the 2026 state DOT construction season is delivering genuinely large new corridor projects, not just maintenance and rehabilitation work. Combined, these two projects represent over $2.3 billion in active construction and five-year construction programs in corridors with significant long-term traffic and economic importance. For the construction industry, the lesson is straightforward: states with committed funding and completed environmental processes are starting work — and the window to capture that work belongs to firms already positioned in those markets.
