Definition and stakes

George R. Chatburn,  Highways and Highway Transportation

“ Each state must select a connected road system not exceeding 7 per cent of its road mileage for improvement with Federal Aid. This system will be divided into two classes, one to be known as “interstate highways” the other as “intercounty highways.” The interstate highways must not exceed three-sevenths of the system selected; on them not more than 60 per cent of the Federal Aid Allotment can be spent without the joint approval of the Secretary of Agriculture and the State Highway Department. The intercounty highways will receive the remainder of the allotment. ”

[N 2] Much of the construction, especially in the solid rock sections, was done by station contracts under which a "station gang" of cooperative laborers contracted to excavate a 100-foot section of road:
These men attack the ledge in various ways.
