9. The apparatus of claim 1 , wherein the support system is formed of a steel.
10. The apparatus of claim 1 , further comprising a slotted strut angle configured to receive a field bolt, and
a formwork, wherein rotation of the rotatable nut adjusts a position of at least one of the support system or the strut angle to adjust a position of the formwork.
11. The apparatus of claim 10 , further comprising a support member and an at least partially transparent panel coupled to the support member.
12. The apparatus of claim 4 , wherein the support system is a first support system, and wherein the second coil rod extends parallel to the flange of the bridge girder to a second support system positioned on another side of the flange of the bridge girder.
13. The apparatus of claim 1 , further comprising at least one connectable strap, wherein the at least one connectable strap is positioned between the first rotatable nut and the first flange of the support system.
14. An apparatus for adjusting a position of a horizontal panel, the apparatus comprising:
a vertical adjustable haunch support comprising:
a support angle, the support angle comprising a first flange and a second flange, wherein a surface of the first flange includes a hole;
a first coil rod at least partially extending through the hole; and
a first rotatable nut at least partially surrounding the first coil rod, wherein motion of the first rotatable nut adjusts a vertical position of the support angle;
a horizontal adjustable haunch support, comprising:
a second coil rod;
a bearing plate; and
a second rotatable nut at least partially surrounding the second coil rod, wherein motion of the second rotatable nut adjusts a horizontal position of the support angle; and
a coupler configured to be embedded within a flange of a bridge girder, wherein the first coil rod is seated within the coupler,
wherein the bearing plate is coupled to the first coil rod and to the second coil rod, and
wherein, when the coupler is embedded within the flange of the bridge girder, the second coil rod extends parallel to the flange of the bridge girder.
15. The apparatus of claim 14 , wherein the support angle is a first support angle, wherein the bearing plate is a second support angle that forms another horizontal adjustable haunch support, and wherein the second coil rod couples the horizontal adjustable haunch support to the another bearing plate of another horizontal adjustable haunch support.
16. The apparatus of claim 14 , wherein the support angle is formed of a steel.
17. The apparatus of claim 14 , wherein the apparatus is a stay-in-place form system configured to receive a concrete pour to form a bridge deck.
18. An apparatus for adjusting a haunch height for a horizontal panel, the apparatus comprising:
a support system, the support system comprising a vertical support portion with a first flange and a horizontal support portion with a second flange, wherein a surface of the vertical support portion includes a hole, wherein the support system is configured to support the horizontal panel;
a first coil rod at least partially extending through the hole;
a first rotatable nut at least partially surrounding the first coil rod, wherein motion of the first rotatable nut adjusts a position of the vertical support portion to adjust a height of the horizontal panel,
