To address these concerns, Symons devised a plan to pour the straight support walls first and then use a combination of systems to create a set of arched forms that could be set up just once and rolled, much like Max‑A‑Form Box Culvert Traveler, from one pour to the next on a system of beams supported by 70K Anchor Brackets mounted to the walls.

The forming scheme utilized a combination of several Symons® by Dayton Superior form‑ ing systems. The Flex- Form forming system, an obvious choice for the curved areas, was complemented by Max-A-Form panels for the straight sections. These high-strength con‑ crete forming systems have a steel face that also provides a smooth finish.

The support for the arched form was accom‑ plished with a mixture of other systems. The Flex-Form panels were supported by horizontal Soldier Beams and Rigid Screw Jacks. Horizon‑ tal, diagonal and vertical Soldier Beams were attached with pivot brackets, Strut Jacks and Max‑A-Form outside corners.

To strip the forms, the contractor adjusted the Rigid Screw Jacks and Strut Jacks to lower the assembly onto 1'-6" soldier beams with custom-mounted rollers. Once lowered, come-alongs were attached to roll the entire assembly to the next bridge pour location.
