The space at the joints is there to allow for expansion and contraction of the length of the bridge depending on the temperature.

Why do engieneers add expansion joints to a bridge in order to make them safer?
The joints are essential to maintain the structural integrity of the bridges components throughout temperature ranges. Heat expands the structures and cold contracts. Without expansion joints the bridges overall life would be greatly reduced and cracks and tears could rapidly develop, making the bridge less safe.

Why do engineers design bridges with expansion slotsions?
Because bridges expand and contract with the change in temperature. The expansion joints allow the bridge to 'flex' as the temoerature rises and falls, ensuring the structure doesn't buckle or collapse.
Expansion joints are used in bridges in order to prevent the bridge from?
Buckling; shriveling, bending, or curling from heating or pressure. (heating, in this case)

What is slide plate?
A slide plate is some linear bearing that makes part of the expansion joints of bridges to allow future expansions and contractions.
How can bridges be built to deal with weather?
They have (overlapping) expansion joints that allows the span to shrink and stretch w/o forming a big gap.
