would not be possible until the region's isolation had been overcome. Because the cost of building highways through Appalachia's mountainous terrain was high, the region's local residents had never been served by adequate roads. The existing network of narrow, winding, two-lane roads, snaking through narrow stream valleys or over mountaintops, was slow to drive, unsafe, and in many places worn out. The nation's

, though extensive through the region, was designed to serve cross-country traffic rather than local residents.
The PARC report and the Appalachian governors placed top priority on a modern highway system as the key to economic development. As a result, Congress authorized the construction of the Appalachian Development Highway System (ADHS) in the Appalachian Development Act of 1965. The ADHS was designed to generate economic development in previously isolated areas of the 13 Appalachian states, supplement the interstate system, and provide access to areas within the region as well as to markets in the rest of the nation.
The ADHS is currently authorized at , including added in January 2004 by Public Law 108–199. A decade into construction, delays and cost increases mounted, attributed to:
*highway construction cost inflation
*upgraded construction guidelines following then-current
Interstate Highway standards

The ARC (the state governors) remain involved prioritizing, sequencing remaining corridor work. By 2040, 100% of ADHS' project miles are expected to be complete and open to traffic or, at least, partially complete.

Economic results
Historically, highway investment has served as the basis for many US regional development policies and in 2008 the ADHS was deemed one of the more comprehensive programs to use the approach.
To evaluate the effectiveness of such investments,

was used to compare 1976 "pre-" and 2002 "post-" highway conditions. The study focused on Ohio's SR-32 portion of Corridor D and the 15 counties in close proximity; Adams, Athens, Brown, Clermont, Gallia, Highland, Hocking, Jackson, Meigs, Morgan, Pike, Ross, Scioto, Vinton, and Washington Counties. Using data acquired from the
Landsat system of earth observational satellites, the comparison revealed slight, yet significant, levels of urban expansion within a band surrounding the new highway. Beyond this band land use was more stable, indicating even minor distance increases from the highway reduced the likelihood of further development.
Detrimentally, by 2016 new business growth along the corridor was drawing consumer traffic away from adjacent towns causing revenue loss and

A 2016 economic assessment of ADHS' construction found regions of Appalachia benefitting differently. Case studies found some boosting tourism income, while others increased industrial activity or commercial/retail activity. Some regions had strong economic growth while others were dormant, the effects dependent on the pre-existing nature of the corridor, its population and workforce, its economic profile and proximity to surrounding business centers or markets.
Case study excerpts from five corridors were:

and new residential and commercial developments near Weaverville, North Carolina. The highway led to a direct increase of around 4,600 new jobs in the area.
*Corridor D (Ohio & West Virginia). Its eastern segment was completed in 1977, connecting interstates I-77 and I-79. This eastern segment shifted its economy from heavy industry into healthcare, education, government and education services. The highway also helped retain indigenous manufacturing activities and enabled around 1,000 new jobs.
*Corridor E (Maryland). Completion of this link (
now part of I-68) enabled the region to boost its pre-existing tourism economy by drawing residents from Washington, DC and Baltimore; expand its pre-existing manufacturing and create new distribution (

*Corridor Q (Kentucky and Virginia). Improved connectivity through this mountainous region increased commuting range, facilitated commercial and retail development in several communities, development of an industrial park and a small business incubator.

. The corridor was critical in the establishment and expansion of manufacturing facilities for diesel engines, furniture and advanced ceramics – all needing interstate trucking connectivity. Over time, the highway was credited with generating over 3,200 jobs in the region.
A 2016–2019 study reported that the cumulative ADHS construction efforts had led to economic net gains of $54 billion (approximately 0.4 percent of national income) and had boosted incomes in the Appalachian region by reducing the costs of trade. The 2021 ADHS Cost-to-Complete Estimate Report reiterated previous compilations that construction investments made between 1965–2015 contributed to the annual generation of over $19.6 B additional Appalachian business sales, representing $9+ B added GRP. Usage of the ADHS was saving 231 million hours of travel time annually, equivalent to a $10.7 B savings in transportation costs and worker productivity per year.
The increased economic activity was helping to maintain or create over 168,000 jobs across the 13 Appalachian states. In 2021 ARC forecast that by 2045 ADHS' construction expenses would yield a return on investment (ROI) of 3.7, meaning $3.70 in benefits for every $1.00 invested in construction.
Employment gains credited to the ADHS were 16,270 new Appalachian jobs as of 1995; 42,190 by 2015.
