This paper studies the nonlocal suspension bridge equation with state-dependent delay in 2D space and the existence of attractors. First, by using Banach fixed point theorem and operator semigroup theory, the existence and uniqueness of mild solutions and continuous dependence on initial values of suspension bridge equations with state delay are proved. Then the bounded dissipativity of the related semi-group and the quasi-stability of the system are verified to obtain a global attractor with finite fractal dimension the existence of the attractor in the generalized index.
