A traveling culvert/tunnel forming structure including upright waler assemblies positioned in transversely spaced relation on each side of said forming structure, the waler assemblies being adapted to receive forms on outside surfaces thereof. Horizontally adjusted header assemblies are supported at opposite ends by the spaced upright waler assemblies. Collapsible braces are disposed between the upright waler assemblies enabling the upright waler assemblies to move towards and away from one another. Multi purpose mounting brackets are mounted in rows on the upright waler assemblies which brackets are positioned inwardly from the waler assemblies. Rows of casters are swivelly mounted on the brackets inside of the rows of upright waler assemblies beneath the header assemblies. A pair of rows of leveling jacks are provided for elevating the forming structure and its casters out-of-contact with a ground supporting surface. The leveling jacks each have an upstanding jack shaft. Threads on the shaft are in threaded retaining engagement with one of the brackets. The shafts are located between the upright waler assemblies and the casters. The leveling jacks are at all times carried on the brackets in assembly with the forming structure and are vertically adjustable for positioning the upright waler assemblies in predetermined adjusted above ground relation to one another.
