A form or a series of forms for forming the bridge diaphragm from concrete material includes one or more bottom walls having an inner surface thereof abutting a bottom surface of the diaphragm. There is at least a pair of side walls upstanding on the inner surface of the bottom wall or walls at a respective longitudinal edge thereof and has an inner surface thereof abutting a respective side surface of the diaphragm. The at least the pair of side walls define each of a generally open top and a generally hollow interior of the form. There is also means for securely attaching each end of the form or series of forms to one of a side surface of at least one of the pair of longitudinal members and an end of another form for forming the diaphragm from the concrete material. Bracing of upper edges is also provided.
In combination with a diaphragm spanning a transverse distance between a pair of spaced-apart longitudinal members employed in a construction of a structure affording vehicle or pedestrian traffic, a form for forming said diaphragm from concrete material, said form comprising:
