Aren’t grid decks noisy and unsafe?

Most grid deck systems are installed with a concrete roadway surface similar to a conventional cast-in-place rebar deck and therefore are typically unnoticed by motorists. However, open grid deck systems can be more noisy and lead to anxiety by drivers’ crossing over long span structures. Slip resistance often is a concern for open grid deck systems. Studies have shown that serrations on the top of the main bars improves traction and diagonal open grid decks are less prone to wheel tracking along the cross bars.
