A changeable message sign structure has a front panel assembly and rear, top, bottom and left and right end panels which define a hollow sign interior. The front panel assembly has a frame with upper, lower and left and right side frame members. At least two vertical support members are attached to the upper and lower frame members. The vertical support members each have a generally T-shaped cross-section with a rearwardly extending stem and left and right arms, each with arm flanges extending rearwardly to define securement slots between the arm flanges and the stem. At least one panel web assembly has frontwardly extending side flanges engaged within a securement slot of each of two neighbouring vertical support members. A web assembly support structure is pressed against the at least one panel web assembly and removably attached to the rearwardly extending stems of two neighbouring vertical support members. At least one changeable message electronic sign module is attached to the web assembly support structure. In another aspect, the invention relates to a method of changing a panel web assembly in the sign structure. The method has the steps of, from the interior of the sign structure, detaching the removably attached web assembly support structure from the rearwardly extending stems of two neighbouring vertical support members, removing an exposed panel web assembly from its position against the arms, positioning a panel web assembly against the arms, pressing the web assembly support structure against the positioned panel web assembly and removably attaching same to the rearwardly extending stems.
