The invention discloses a surface seamless type bridge expansion joint structure which comprises vertical center plates fixed to the sides, close to each other, of concrete splice plates, a transverse center plate is arranged between the two vertical center plates close to each other, plugging mechanisms are arranged on the two sides of the transverse center plate correspondingly, and each plugging mechanism comprises a plugging strip used for abutting against the corresponding vertical center plate. A mounting groove is formed in one side of the plugging strip, the banner plate is arranged in the mounting groove in a sliding mode, a thrust assembly used for enabling the plugging strip to abut against the vertical plate is arranged in the mounting groove, and a supporting mechanism used for preventing the banner plate from moving is arranged on the banner plate. The expansion joint has the effects that the possibility that hard impurities are mixed in the expansion joint is reduced, and the expansion stabilit
