Abstract: A conduit segment casting mold system includes at least one inner mold; at least one outer mold configured as at least two outer mold sections of opposed shapes that define a cavity between the at least two outer mold sections that is sized to at least partially enclose the at least one inner mold, each of the at least two outer mold sections including a respective mating surface, each of the at least two outer mold sections including at least one hole sized to receive a cable, and the at least one hole of a particular one of the at least two outer mold sections is aligned with the at least one hole of another particular one of the at least two outer mold sections when the mating surfaces of the particular one and the another particular one of the at least two outer mold sections are mated; and a mold base.

Abstract: A roadway conduit system includes a roadway conduit section that includes a floor portion with roadway surface configured to receive traveling vehicles, a ceiling portion, and at least one sidewall portion coupled to the floor portion and the ceiling portion such that the floor, ceiling, and at least one sidewall portions define a roadway conduit volume through which the traveling vehicles traverse the roadway conduit section. The roadway conduit section includes at least two fixedly connected preformed segments. The roadway conduit system also includes a roadway conduit ingress coupled to a first location of the roadway conduit section; a roadway conduit egress coupled to a second location of the roadway conduit section; and at least one air mover configured to circulate an airflow in the roadway conduit volume in a direction of at least one of the traveling vehicles.
