The gaps allow the steal to expand as the day gets hotter, and prevent the steal from buckling.

Why do metal bridges have gaps at one end?
So it can expand
Why do foot paths rail-tracks and bridges have gaps between them?
please tell me the answer!
Why are many bridges built with gaps in them?
so that if they calaps the other one will not calaps together
What is the gaps in bridges used for and what material?
it is used so when sunlight falls on the bridge and it will expand so it will no crack
What is the cheapest type of bridge?
beam bridges are usually the cheapest. The cost usually depends on the size of the bridge and the materials used. Beam bridges usually consist of storng wood and san small gaps, therfore being the cheapest to build. Although they are cheap, they are not the strongest nor the most reliable and can not span large gaps.
Why do roads over bridges have small gaps in them?
To allow them to expand and contract with heat and cold. Without those, the road would end up buckling.
What is the property of matter where it changes volume when it changes temperature?
The property of solids in which they enlarge when warmed is thermal expansion. The opposite, shrinking when cooled, is thermal contraction. This property greatly effects how bridges, sidewalks, and concrete roads are made. They all have "expansion gaps," gaps between sections that allow the sections to expand in the heat of summer. Without those, the concrete would break and the bridges would warp and bend.
What metal is very strong and is used to build bridges?
some materials used in bridges are concrete, steal, metal [may rust and fall if metal ] the first bridge may or may not have been made of wood
How do you capitalise gaps in research?
I assume the question is about 'gaps in research'? If beginning a sentence: Gaps in research. If part way along a sentence: '...gaps in research....' If part of a title: Gaps In Research.
Why small gaps are left in between two adjacent pieces of railway track?
These gaps are thermal expansion joints, they prevent the rails from buckling when they get hot in the summer. Although modern welded rail only has these gaps every mile or so to reduce the vibration and noise of the wheel crossing them (instead of every 40 feet on unwelded rail). All construction must provide for thermal expansion (e.g. bridges have thermal expansion joints, concrete road paving has thermal expansion grooves).
What is the cheapest bridge in the world?
beam bridges are usually the cheapest. The cost usually depends on the size of the bridge and the materials used. Beam bridges usually consist of storng wood and san small gaps, therfore being the cheapest to build. Although they are cheap, they are not the strongest nor the most reliable and can not span large gaps.
When molecules move closer together in a bridge during winter how does a bridge not break from the molecules coming closer together?
They design bridges with mechanical sliding gaps to avoid any damage due to thermal expansion/contraction.
