What happens to a bridge's expansion joints on a hot day?

If there is no expansion joints on a bridge and if it's really hot the molecules of the bridge will be separated slowly and the bridge will collapse

Why are there joints in bridges?

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

What type of bridge is the sunshine skyway bridge?

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.

What has the author W Black written?

What is an expansion bridge?

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.
