         4 . The formwork support system of  claim 1 , further comprising one or more holes in a rear portion of the main body, wherein the one or more holes are placed to allow the web shoe to be secured to a surface. 
     
     
         5 . The formwork support system of  claim 1 , further comprising one or more removable vertical adjusters comprising:
 (a) a first elongate portion having a first end and a second end;   (b) a second elongate portion having a first end and a second end;   (c) an elongate projection extending transversely through the first end of the first elongate portion;   (d) an adjustment bolt extending vertically through the second end of the first elongate portion and the second end of the second elongate portion; and   (e) an axis point between the first end and second end of the second elongate portion,   wherein the first elongate portion is rotatable relative to the second elongate portion at the axis point by actuation of the adjustment bolt.   
     
     
         6 . The formwork support system of  claim 5 , wherein the elongate projection is configured to be inserted into the opening. 
     
     
         7 . The formwork support system of  claim 1 , further comprising one or more removable horizontal adjusters comprising:
 (a) one or more planks; and   (b) a thrust bolt assembly, comprising:
 (i) a thrust bracket attached to the plank and 
 (ii) a thrust bolt inserted through the thrust bracket, 
   wherein actuation of the thrust bolt urges the one or more planks horizontally.   
     
     
         8 . The formwork support system of  claim 7 , wherein the one or more planks are connected to each other and form a deck. 
     
     
         9 . The formwork support system of  claim 8 , wherein the thrust bolt assembly is configured to abut a section of formwork against a bridge girder. 
     
     
         10 . A formwork support system comprising:
 (a) one or more shoes comprising:
 (i) a main body; and 
 (ii) a hinged flap rotatably attached to the main body, 
 wherein the main body and the hinged flap define an opening when the hinged flap is in a closed position; and 
   (b) one or more removable vertical adjusters comprising:
 (i) a first elongate portion having a first end and a second end; 
 (ii) a second elongate portion having a first end and a second end; 
 (iii) an elongate projection extending transversely through the first end of the first elongate portion, wherein the elongate projection is configured to sit within the opening of the shoe; 
 (iv) an adjustment bolt extending vertically through the second end of the first elongate portion and the second end of the second elongate portion; and 
 (v) an axis point between the first end and second end of the second elongate portion, 
   wherein the first elongate portion is rotatable relative to the second elongate portion at the axis point by actuation of the adjustment bolt.   
     
     
         11 . The formwork support system of  claim 10 , wherein the hinged flap is rotatably attached to the main body by means of an axis. 
     
     
         12 . The formwork support system of  claim 10 , further comprising a horizontal adjustment assembly comprising:
 (a) one or more planks;   (b) a thrust bracket attached to one or the one or more planks; and   (c) a thrust bolt inserted through the thrust bracket,   wherein actuation of the thrust bolt urges the thrust bracket and one or more plank horizontally.   
     
     
         13 . The formwork support system of  claim 10 , further comprising at least one opening in a rear portion of the main body for insertion of a bolt to attach one of the one or more shoes to a surface. 
     
     
         14 . A method of forming a bridge overhang comprising:
 securing a web shoe to a surface via a bolt;   assembling a gang of formwork brackets including a surface, a horizontal adjuster, and a vertical adjuster, where the horizontal adjuster is attached to the vertical adjuster and the surface is supported by the horizontal adjuster; and   inserting an elongate projection of a vertical adjuster to the web shoe such that the gang of formwork is supported by the web shoe.   
     
     
         15 . The method of  claim 14 , wherein the vertical adjuster comprises:
 (i) a first elongate portion having a first end and a second end;   (ii) a second elongate portion having a first end and a second end;   (iii) an adjustment bolt extending vertically through the second end of the first elongate portion and the second end of the second elongate portion; and   (iv) an axis point between the first end and second end of the second elongate portion,   wherein the elongate projection extends transversely through the first end of the first elongate portion.   
     
     
         16 . The method of  claim 15 , further comprising actuating the adjustment bolt on the vertical adjuster. 
     
     
         17 . The method of  claim 15 , further comprising urging the surface horizontally via the horizontal adjuster, the horizontal adjuster comprising:
 (a) one or more planks; and   (b) a thrust bolt assembly, comprising:
 (i) a thrust bracket attached to the plank and 
 (ii) a thrust bolt inserted through the thrust bracket, 
   wherein actuation of the thrust bolt urges the one or more planks horizontally.   
     
     
         18 . The method of  claim 14 , wherein the surface is a bridge girder. 
     
     
         19 . The method of  claim 14 , further comprising: setting rebar and pouring concrete on the surface. 
     
     
         20 . The method of  claim 14 , further comprising attaching a rail to the gang of formwork brackets.
