US Interstate Freight Corridors

Route

Jacksonville, FL to Santa Monica, CA in the Los Angeles metro, crossing Florida, Alabama, Mississippi, Louisiana, Texas, New Mexico, Arizona and California. Texas alone accounts for 878.76 of the 2,457.62 miles in the FHWA Route Log — more than a third of the corridor.

What moves

Cross-border freight dominates the Texas segments, particularly between El Paso and San Antonio. Petrochemicals and energy equipment move between Houston and New Orleans along the Gulf Coast refinery corridor. Florida and California bookend the route with produce — Florida citrus and vegetables January through May, California produce year-round. Consumer goods run the full length, feeding distribution centres from Jacksonville to the Inland Empire. That variety is I-10's real advantage: it is the corridor where a carrier is least likely to be locked out by equipment type or season.

Key segments

• •Houston to San Antonio — petrochemical and energy freight. Refineries, chemical plants and oilfield services generate flatbed and tanker loads, and demand tracks crude prices rather than the retail calendar.
• •El Paso to Tucson — cross-border corridor. Freight from Mexican manufacturing enters at El Paso and moves west toward Arizona and California distribution centres.
• •Inland Empire to Phoenix — port import distribution. Goods arriving at Los Angeles and Long Beach move east to Arizona distribution centres, and port freight has no true off-season.

Route

Laredo, TX to Duluth, MN through Texas, Oklahoma, Kansas, Missouri, Iowa and Minnesota. I-35 is the primary north-south road link between Mexico and the American Midwest. The old “NAFTA superhighway” nickname is out of date: NAFTA was replaced by the United States-Mexico-Canada Agreement, which entered into force on July 1, 2020.

What moves

Cross-border imports dominate the southern segments — automotive parts, electronics, appliances and fresh produce moving north out of Laredo into the US distribution network. Consumer goods run in both directions the full length, feeding Dallas-Fort Worth, Oklahoma City, Kansas City and the Twin Cities. Agriculture is the backbone of the northern segments, with Kansas and Iowa grain moving south and Texas produce moving north. Energy equipment moves between the Texas and Oklahoma oil patches and Midwest manufacturing. For what is driving volume on this corridor right now, see our coverage of cross-border freight in 2026 and how nearshoring is reshaping truckload demand.

Key segments

• •Laredo to San Antonio — the border segment. Customs processing times limit how many trucks clear per day, which keeps capacity tight on the northbound side. It is a short segment, so watch the repositioning leg into Laredo carefully; it can be the difference between a good week and a break-even one.
• •Dallas-Fort Worth to Oklahoma City — mixed freight combining energy loads, consumer goods and manufacturing. DFW is one of the largest inland freight markets in the country, so load availability in every direction is reliable.
• •Kansas City to Des Moines — agricultural corridor. Grain, livestock feed and processed food move year-round, with harvest from August through November tightening capacity for flatbed and hopper carriers.

Route

Wilmington, NC to Barstow, CA through North Carolina, Tennessee, Arkansas, Oklahoma, the Texas Panhandle, New Mexico, Arizona and California. Tennessee (455.44 miles) and North Carolina (420.06) are the two longest state segments in the FHWA Route Log, which is why the eastern half behaves like a distribution corridor and the western half like a land bridge.

What moves

North Carolina and Tennessee generate manufacturing freight — furniture, textiles, auto parts and industrial equipment. Memphis is the anchor of the middle: a global air cargo hub with multiple Class I rail connections, which makes it one of the densest pickup markets on the corridor. Oklahoma and the Texas Panhandle contribute energy equipment and agricultural loads. The western segments through New Mexico and Arizona carry consumer goods and intermodal transfers moving to and from Southern California, with Flagstaff to Barstow acting as the feeder into the Los Angeles basin and the Inland Empire warehouse complex.

Key segments

• •Memphis to Little Rock — distribution hub corridor. Memphis supplies the volume and Little Rock anchors Arkansas's distribution network, so loads are available in both directions most of the year.
• •Amarillo to Albuquerque — long and sparse. This stretch crosses the Texas Panhandle and eastern New Mexico with few freight origins and thin services. Transit it with a load already booked; parking options are limited enough that it is worth reading our truck parking guide before you plan the clock on it.
• •Flagstaff to Barstow — the gateway into Southern California freight. Westbound loads position you into one of the largest freight markets in the country, which matters more than the rate on the leg itself.

Route

Teaneck, NJ to San Francisco, CA, crossing New Jersey, Pennsylvania, Ohio, Indiana, Illinois, Iowa, Nebraska, Wyoming, Utah, Nevada and California. At 2,891.59 miles it is the longest interstate in the FHWA Route Log, and it is the primary northern east-west freight artery between the Eastern Seaboard and the Bay Area.

What moves

Intermodal freight out of Chicago dominates the middle. Chicago is the central rail-to-truck interchange point in North America, and containers transfer to truck there every day for final-mile delivery across the Midwest and East. Midwest manufacturing — automotive, steel, machinery — generates heavy outbound loads from Ohio, Indiana and Illinois. Iowa and Nebraska grain, corn and soybeans move in every direction through harvest. Port freight bookends the route: the Port of New York and New Jersey at the eastern end and Oakland at the western end.

Key segments

• •Northern New Jersey — port and drayage market. I-80 runs only 68.56 miles in New Jersey, but it terminates in the middle of one of the busiest container markets in the country, which makes it a short-haul segment rather than a long-haul one.
• •Chicago corridor — intermodal capital. Rail-to-truck transfers generate a constant stream of loads in every direction, which is why Chicago is the easiest place on the corridor to get reloaded quickly.
• •Nebraska (Omaha) — food processing. Nebraska is a leading beef-processing state, and the plants around Omaha generate steady reefer volume year-round. I-80 crosses 455.18 miles of Nebraska, the longest single-state segment on the route.
• •Wyoming — 402.59 miles of pass-through territory. Freight origins are sparse; treat it as transit, not as a freight source.
• •Nevada to California — Bay Area connector. Reno has a distribution cluster feeding the Sacramento and Bay Area markets, which gives the western end more origin freight than it once had.

Routes

I-75 runs 1,693.48 miles from Miami, FL to Sault Ste. Marie, MI through Florida, Georgia, Tennessee, Kentucky, Ohio and Michigan. I-95 runs 1,904.61 miles from Miami, FL to Houlton, ME across fifteen states and the District of Columbia. Together they are the north-south spine of eastern freight, linking the Great Lakes manufacturing belt to the Southeast distribution network and Florida's consumer and produce markets.

What moves

Between them, close to everything. Port freight flows through Miami, Jacksonville, Savannah, Charleston, Norfolk and Newark. Florida produce — citrus, tomatoes, peppers, strawberries — moves northbound on both routes from January through May, and it is the strongest reefer season on the eastern half of the country; our produce season guide covers the timing region by region. Automotive freight dominates I-75 from Michigan through Ohio, Tennessee and into Alabama. Retail distribution drives steady demand through Atlanta, Charlotte and the DC-to-New-York corridor.

Key segments

• •Miami to Atlanta (I-75) — produce and retail. Florida produce from January through May is the reason to be here; year-round retail fills the gaps between seasons. I-75 runs 470.74 miles in Florida alone.
• •Atlanta to Chattanooga (I-75) — automotive corridor. Assembly plants and parts suppliers line the segment, generating consistent flatbed and dry van work.
• •Cincinnati to Detroit (I-75) — automotive parts. Parts move between suppliers and assembly plants several times before a finished vehicle ships, which creates dense short-haul demand rather than long-haul rate opportunities.
• •DC to NYC (I-95) — the densest consumer market in the country, and the most punishing on hours. Congestion through Baltimore, Wilmington and the New Jersey approaches eats transit time that never appears on the rate confirmation.
• •Jacksonville to Savannah (I-95) — port freight. Both are container ports generating drayage and long-haul loads heading inland to Atlanta, Charlotte and the Midwest.

Route

Boston, MA to Seattle, WA, crossing Massachusetts, New York, Pennsylvania, Ohio, Indiana, Illinois, Wisconsin, Minnesota, South Dakota, Wyoming, Montana, Idaho and Washington — more states than any other corridor here. The FHWA Route Log puts it at 2,705.99 miles. Lengths above 3,000 miles that you will see quoted elsewhere count the sections concurrent with I-94 and I-80 differently.

What moves

Manufacturing freight dominates the eastern and central segments: Ohio, Indiana and Wisconsin produce automotive parts, industrial equipment, paper products and machinery moving east to New England and west to the Pacific Northwest. Agricultural products move heavily through Minnesota and South Dakota at harvest — grain, corn, soybeans and sugar beets. Energy freight moves through Wyoming and Montana, though volumes are cyclical and tied to commodity prices. Technology and consumer electronics move through the Seattle-Tacoma corridor, and the Ports of Seattle and Tacoma generate inbound import freight heading east.

Key segments

• •Boston to Buffalo — the Mass Pike and NY Thruway. Albany and Syracuse are modest freight markets, but Buffalo opens the I-79 and I-81 network into Pennsylvania and the Great Lakes. I-90 runs 386.27 miles in New York, its longest eastern state segment.
• •Cleveland to Chicago — industrial heartland. Steel, automotive and manufacturing freight create the densest load availability on the eastern half of I-90. Note that I-90 and I-80 run concurrent for much of this stretch, so a load posted on one is often physically on both.
• •Minneapolis to Sioux Falls — agricultural transition zone. The Twin Cities are a strong origin market, but loads thin out quickly heading west. Book your pickup in Minneapolis, not along the way.
• •South Dakota through Montana — 412.76 miles of South Dakota followed by 544.70 miles of Montana, roughly 957 miles of freight-sparse country back to back. Bakken energy loads exist in western North Dakota and eastern Montana but require detours off I-90.
• •Spokane to Seattle — Pacific Northwest connector. Washington apples, wheat and hops combine with port and technology freight to give the westbound leg a market, and eastbound loads out of Seattle are supported by port import volume.
