A report titled "Future Options for the National Interstate And Defense Highways" was prepared May 2007 by PB Consult, Inc and Cambridge Systematic for the National Cooperative Highway Research Program (NCHRP) of the Transportation Research Board (TRB) of the National Academies. The work was sponsored by the American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA). A conclusion was that the capacity of the Interstate System needed to be increase in two parts defined as "expansion" {additional lanes and interchanged} and "extension" {extension of existing or totally new Interstate highways},

System Extent. The application of performance criteria in the context of the growth in demand and the specific functional needs of connections and continuity has indicated the need for an additional 173,000 lane miles of capacity to be added to the 210,000 lane miles of the existing Interstate System....this new capacity would be achieved in two ways:

· Expansion of the existing Interstate System, adding 88,600 lane miles within its existing 212,000 lane miles on 46,800 route miles.

· Extensions of the existing Interstate System, through upgrades of the national highway system (NHS) and related corridors, converting 15,000 route miles to the Interstate, involving an additional 84,400 lane miles.

In total, the future Interstate System would supply 385,000 total lane miles of capacity along a total system length of nearly 62,000 route miles. Accommodating the forecasted travel at the performance level used in this analysis implies the addition of about 5,760 lane miles per year.

The Interstate System was never a "fixed" system, but has evolved from its inception as the Inter-Regional System, to additions replacements of routes like I-67 into I-69, the extension of I-70 from I-25 in Denver to I-15 in Utah, and I-12 as an intercontinental bypass north of New Orleans. The Federal Aid Highway Act of 1968 added 1500 miles that created I-49 and I-22. The Federal Aid Highway act of 1988 and ISTEA 1991 planned the extension of I-49 from Shreveport to Kansas City and I-69 from Indianapolis to Texas. The new Future Interstate Study will create totally new numbered Interstates as well of extending existing Interstate. Most of these routes will follow the existing National Highway System (NHS) corridors, but will also follow non-NHS corridors to increase capacity to relieve BOTH congested urban and rural routes. The new Interstate mileage corridors may increase the Interstate system to about 15,000 miles or more. The estimated Future Interstate System may total 67,000 miles. The new routes will match similar routes suggested in the large 78,000 mile system studied in 1941 Inter-Regional System. This is not surprising since the 78,000 mile Inter-Regional network was based on interconnecting the majority of cities that were strategic to the defense of the United States as submitted by General Pershing (and his aid Dwight Eisenhower, the future President and "father" of the Interstate System.

Section 6021 of the new Fixing America's Surface Transportation Act of 2015 has commissioned the Transportation Research Board to conduct a detailed study on the actions needed to upgrade the original "Dwight D. Eisenhower" National System of Interstate and Defense Highways to meet the growing new highway demands of the 21st century. In the 2007 study, the major freight truck corridor and the truck traffic bottleneck cities are shown in the tow maps below.

The Congress decided to completely study the need improvements to the Interstate System for the 21st Century, INCLUDING upgrading National Highway System (and some non-NHS corridor were needed) to Interstate Highway standards both by extending existing Interstate or adding totally new numbered Interstates (like I-42 and I-87 in North Carolina, I-14 in Texas, I-57 in Arkansas) in the 2015 FAST Act. The Transportation Research Board suggest an additional 15,000 miles in its 2007 study:

(f) REPORT.—Not later than 3 years after the date of enactment of this Act, the Transportation Research Board shall submit to the Secretary, the Committee on Environment and Public Works of the Senate, and the Committee on Transportation and Infrastructure of the House of Representatives a report on the results of the study conducted under this section.

(g) FUNDING.—From amounts authorized to carry out the Highway Research and Development Program, the Secretary shall use to carry out this section not more than $5,000,000 for fiscal year 2016.

The Transportation Research Board will investigage new Interstate corridor ranging from the existing Interstate Corridors created by Congress since 1991, and new Interstate freeway upgrades of existing US Routes in the National Highway System. All of these new corridors will be created as alternate relief routes to existing high traffic Interstate highway, to increase the capacity of NHS routes that have increased traffic, and in some cases, to provide new economic trade corridors. Many of these corridors have be recognized as vital since the 1941 study of a 78,000 mile interstate highway system that was the basis for the 45,000 mile system approved in the 1957 Interstate Higway System. The new study will propose totally new Interstate Corridors along non-NHS corridors which are needed to relieve traffic bottlenecks that are growing in the existing Interstate System.

Future Interstate Historical Corridors

The Future Interstate Historical Corridors alleviate traffic congestion, fosters economic growth and commemorates historical cultures that struggled for the freedom in the United States of America. The Transportation Research Board concluded the nation's interstate highway system needs to increase the efficiency of traffic flows to lead to more prosperity. Congress needs to commemorate historical cultures that struggled through injustice to achieve freedom in America.

By creating additional interstate corridors strategically located to divert traffic away from congested areas while connecting regions with untapped economic potential, we unlock opportunities for growth in low populated areas. The improved transportation infrastructure leads to increased job creation, enhanced trade opportunities between states, and overall economic prosperity. Investing in these new corridors now produces sustained economic development across various industries of tourism, manufacturing, agriculture, and high technology. Beyond the purely practical considerations, these future interstate corridors present an incredible opportunity to commemorate our nation's diverse historical cultures and event.

The future interstate corridors will be expensive, however new renewable electrical power systems build along these corridors can achieve both reducing environmental impact while at the same time provide a new revenue source to cover the cost of their construction. Building solar farms along the paths of these corridors, located every 50 miles produces clean energy for electric vehicle charging independent of fossil fuels where the excess power not used for electric charging can be sold to local utilities. A 300-mile highway with 640-acres of solar farms stretched over a 50-mile interval can produce $1 billion per year that can be paid into the Federal Aid Highway Trust fund and state transportation departments based on an agreed cost share formula. The solar farm system can be built as soon aht the routes are selected and approved in the Draft and Final Environmental studies. Constructing the solar farms can be paid initially by Federal grants or loans which can be repaid within 2 years after completion by immediately selling power to the local grid. After the initial 2 year payoff period, the revenue can be paid into the Federal-Aid Highway Trust fund and state transporation budget to pay for detailed engineering design and during actual construction which typically takes about 5 years. Highway construction cost can be paid as-you-go over a 3-6 year period depending on the cost per mile. After construction costs are covered the revenue then continues into the Federal-Aid Highway Trust Fund and state budget to maintain the highway and help build other highway projects. A state is free to form public-private-partnerships, regular state bonds and tolling if the project will exceed the revenue rate, although this last option should be used as a last resort, and the tolls removed when basic construction costs are paid-off.
