§ 776.29 Instrumentalities and channels of interstate commerce.

(a) Typical examples. Instrumentalities and channels which serve as the media for the movement of goods and persons in interstate commerce or for interstate communications include railroads, highways, city streets; telephone, gas, electric and pipe line systems; radio and television broadcasting facilities; rivers, canals and other waterways; airports; railroad, bus, truck or steamship terminals; freight depots, bridges, ferries, bays, harbors, docks, wharves, piers; ships, vehicles and aircraft which are regularly used in interstate commerce. ^[1]

(b) General character of an instrumentality of interstate commerce. (1) An instrumentality of interstate commerce need not stretch across State lines but may operate within a particular State as a link in a chain or system of conduits through which interstate commerce moves. ^[2] Obvious examples of such facilities are railroad terminals, airports which are components of a system of air transportation, bridges and canals. A facility may be used for both interstate and intrastate commerce but when it is so used it is nonetheless an interstate instrumentality. Such double use does not exclude construction employees from being engaged in commerce.

(2) The term instrumentality of interstate commerce may refer to one unit or the entire chain of facilities. An instrumentality such as a railroad constitutes a system or network of facilities by which the interstate movement of goods and persons is accomplished. Each segment of the network is integrally connected with the whole and must be viewed as part of the system as a whole, not as an isolated local unit.

(3) A construction project which changes the interstate system as a whole, or any of its units, would have a direct bearing on the flow of interstate commerce throughout the network. Thus, the new construction of an alternate route or an additional unit which alters the system or any segment of it, would have such a direct and vital relationship to the functioning of the instrumentality of interstate commerce as to be, in practical effect, a part of such commerce rather than isolated local activity. For example, such construction as the maintenance, repair, replacement, expansion, enlargement, extension, reconstruction, redesigning, or other improvement, of a railroad system as a whole, or of any part of it, would have a close and intimate relationship with the movement of goods and persons across State lines. All such construction, therefore, is subject to the Act.

(4) The same would be true with respect to other systems of interstate transportation or communication such as roads, waterways, airports, pipe, gas and electric lines, and ship, bus, truck, telephone and broadcasting facilities. Consequently, construction projects for lengthening, widening, deepening, relocating, redesigning, replacing and adding new, substitute or alternate facilities; shortening or straightening routes or lines; providing cutoffs, tunnels, trestles, causeways, overpasses, underpasses and bypasses are subject to the Act. Furthermore, the fact that such construction serves another purpose as well as the improvement of the interstate facility, or that the improvement to the interstate facility was incidental to other non-covered work, would not exclude it from the Act's coverage. ^[3]

(c) Examples of construction projects which are subject to the Act. Coverage extends to employees who are engaged on such work as repairing or replacing abutments and superstructures on a washed out railroad bridge; ^[4] replacing an old highway bridge with a new one at a different location; ^[5] removing an old railroad bridge and partially rebuilding a new one; repairing a railroad roundhouse, signal tower, and storage building; relocating portions of a county road; erecting new bridges with new approaches in different locations from the old ones; widening a city street; relocating, improving or extending interstate telephone facilities including the addition of new conduits and new trunk lines. ^[6] Also within the scope of the Act are employees who are engaged in the construction, maintenance and repair of ships, barges and other vessels used for interstate commerce, including those belonging to the Government, ^[7] and facilities used in the production and transmission of electric, fuel, water, steam and other powers to instrumentalities of interstate commerce. ^[8]
