## Abstract

A device and a system for an oil field road crossing and a method of installing thereof. A plurality of conduits having a rectangular cross-section with a coupling header on each end are set in the ground at the road crossing, the conduit top surfaces substantially level with the ground. The long sides of adjacent conduits are welded together in parallel. The coupling headers are in fluid communication with the rectangular conduit, each header have an open end operative to connect to the end of a cylindrical pipeline. When cylindrical pipelines are connected to the headers, one at each end of the rectangular conduit, the pipelines are in fluid communication with each other. The flat surfaces of the rectangular conduits form a road crossing substantially level with the ground for a vehicle to safely travel over without disrupting flow through the pipelines absent burying the pipelines.

## Claims

### Claim 1

A road crossing device operative for a vehicle to cross over a conduit in an oil field, comprising:
a rectangular conduit having a rectangular cross-section, a pair of long sides, a flat top surface and a flat bottom surface, and a pair of ends having an edge at the end of the conduit on the conduit sides, on the top surface, and on the bottom surface, wherein a cylindrical pipeline is inside the rectangular conduit therethrough, the cylindrical pipeline having an integral coupling header operative for connecting to another cylindrical pipeline above ground; and
a pair of coupling headers, a coupling header at each end of the rectangular conduit, each coupling header includes a top plate and a bottom plate, the plates each having an edge, the top plate of each header welded to and in fluid communication with the edge of the top surface of the rectangular conduit and the bottom plate of each header welded to and in fluid communication with the edge of the bottom surface of the rectangular conduit, the welded headers forming a gas tight connection with the conduit, each top plate having an opening to which is coupled a pipe with a pair of ends, a first end connecting to an annular collar, and a second end connecting to the opening in each top plate, the annular collar operative for selectively connecting to a cylindrical pipeline above ground when the device is set on the ground, the headers including a side plate, the side plates having a pair of long edges and a pair of short edges, each short edge welded to the edges at the ends of the sides of the rectangular conduit, one short edge on each opposing sides, one long edge of the side plate welded to the edges of the top plates of the headers and one long edge welded to the edges of the bottom plate headers, the device having the flat top surface of the conduit substantially level with the ground, the device set at a road crossing for a vehicle to safely travel over without disrupting the flow of a fluid through the cylindrical pipeline above ground adjacent to the road crossing, the pipeline selectively connecting to the coupling headers.

### Claim 2 (depends on 1)

The road crossing device as described in claim 1, wherein the device has a plurality of rectangular conduits in a parallel position, the long side of each conduit welded in the parallel position to the long side of an adjacent conduit, the parallel welded conduits forming a cluster, wherein the cluster of conduits has a center portion of conduits having a pair of sides and a pair of side portions, the side portions connected to the side of the center portion, one side portion on each side, the side portion conduits having decrementally shorter sides, the conduit with the shortest side positioned farthest from the center portion, such that the top surfaces of the side portions decline away from the center portions, forming a pair of ramps on each side of the center portion.
