First, to eliminate some confusion, thanks to a posting by Paul Wolf: All
highways in the US, except on federally-owned land (such as within
national parks) are state or locally maintained, although many are
eligible for federal aid in construction. The Interstate system created in
1956 has a specific set of design criteria, and specific funding ratios.
The design criteria and funding ratios are different from that of the 1926
Federal system. The standards include a minimum of four 12-foot wide
travel lanes, a minimum shoulder width of 10 feet, full control of access,
and design speeds of 50 to 70 miles per hour (depending on the type of
terrain). Initially, the design had to be adequate to meet the traffic
volumes expected in 1975. Later, the requirement was changed to a more
general 20-year design period rather than for a specific year to allow for
evolution of the System. The design standards have been codified in
Section 109(b), 23 U.S.C.
[Information on the Design Standards from the FHWA
Interstate Log]
The Federal government, working with the states, established the system (i.e. designated the general corridors, but not the exact locations) and allocated the mileage to the states. The states designed and built the roads, with the Federal government reviewing and approving the plans. States could, and did, decide not to build portions of the system. There are also routes built to the standards of the system, usually with some percentage of federal money, that were not chargeable to the mileage in the system, but were signed as part of the system.
The Interstate System was created by the 1944 Federal-Aid Highway act, which authorized 40,000 miles nationally. California was initially allocated 1,938 miles. Later allocations in 1955 brought the total mileage to 2,135 miles. The 1956 Federal-Aid Highway Act authorized an additional 1,000 miles nationally; California received none of this. The 1968 Highway Act added another 1,500 miles, expanding the system to 42,500 miles. An amendment sponsored by U.S. Representatives James Howard and William Cramer authorized an additional 200 miles for modification or revision of the basic System. The mileage authorized under the Howard-Cramer Amendment was increased eventually to 500 miles under the Federal-Aid Highway Act of 1973. The Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 brought the total authorized mileage to 43,000. Of these miles, California has been allocated 2,311 miles. This mileage is called "chargeable Interstate". All of this mileage is/was eligible for construction with regular Interstate funds.
The Surface Transportation Assistance Act of 1978 provided full Interstate Construction funding for all routes designated under previous system adjustments. Another provision of this Act prohibited the use of Interstate Construction (IC) funds for the construction of any new miles designated after passage of the Act. A total of 42,795 miles had been designated for development with IC funds before this measure was enacted.
The following summarizes California's chargeable Interstate mileage:

Section 139, Title 23 of the US Code allows for the designation of certain highways as Interstate routes in addition to that which is "chargeable". These highways are not eligible for regular Interstate Completion funds and are called "Non-chargeable Interstates". They are all Federal-aid Primary highways that meet the criteria for Interstate routes. They are signed as interstates to provide continuity and connectivity for motorists and truckers. There are two types:
Note that the section numbers have changed. According to the FHWA log:
The FHWA may, at the request of a State or States, designate sections of the National Highway System (NHS) as Interstate Highway under Section 103(c)(4)(A), Title 23, United States Code (23 U.S.C.). The proposed section must:
- Be built to Interstate standards and
- Be a logical addition to the System.
Although Section 103(c)(4)(A) segments look like any other Interstate highway, they are not eligible for development with IC funds. In all, the FHWA has approved 2,145.29 miles of highways in the contiguous 48 States, District of Columbia, and Hawaii as Section 103(c)(4)(A) additions to the Interstate System (including additions under former Section 139(a)).
Also added to the Interstate System under Section 103(c)(4)(A) are highways in Alaska and Puerto Rico for a total of 1,331.99 miles (including additions under former Section 139(c)). Alaska and Puerto Rico are exempt from the design standards of Section 109(b). Section 103(c)(1)(B)(ii), 23 U.S.C., states: "Highways on the Interstate System in Alaska and Puerto Rico shall be designed in accordance with such geometric and construction standards as are adequate for current and probable future traffic demands and the needs of the locality of the highway."
The FHWA may also, at the request of a State or States, add highways to the Interstate System that are designated as National Highway System (NHS) high priority corridors and future parts of the Interstate System in Section 1105 of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA). The proposed section must:
- Be built to Interstate standards and
- Connect with an existing Interstate route.
The following is a summary of California's non-chargeable interstate mileage:
