Like when your driving over a tall bridge and you are above the tree tops and all the same level... I know not all are planted at the same time.... so why?

Because their genetics limit their maximum height, just like the genetics of all living things indicate how large or small they will be.

They may have all been planted at the same time, but even if they are not, trees have the same kind of genetic potential as humans and animals. Just as hardly any humans will ever be more than seven feet tall, or no horse will be bigger than the biggest Clydesdale, trees will only get just so big, depending on the variety. If you go to a plant nursery, they have tags on them that tell you how tall the tree will get. Some will only grow to 25-30 feet, others go to 60-100. And, since all the trees planted in the same location are getting more or less the same light, water, and nutrients, if they are all the same type, the will hit that maximum for their species and stop growing taller. Plant biologist spend a lot of time breeding hybrids of plants that will be larger than average, but in the end, you are just making sure they reach maximum potential.
Also, remember that a stand of trees in the wild is related, sort of like a family of kids. The more genes living things have in common, the more alike they are. Sometimes, what looks like a lot of trees is actually one tree that sent out runners and spread that way, sort of like clones. Those trees are genetically identical to one another.

Some trees grow taller than others. All trees have a limit to how tall they will
grow. Trees are like people in that, for a given kind (red maple, white oak,
American holly, etc.) some individuals grow taller than others.
Generally, as long as a tree is alive, it will continue to get fatter. Gravity
may limit the height, as will damage to the leader (the tallest main branch, or
shoot).

every tree is different along with their characteristics.. for example a tomato plant has a certain height & an apple or peach tree has a certain height with that in mind if you plant all peach tree or apple tree they will allstop at a certain height.
If you watch people walking on a busy street, everyone looks the same height even though there might be difference between all the people.
Hope this helps

Most of the other answer give are correct, however, I think there is more to it.
Tree compete for the light, trying to get higher than their neighbors so they can get more. So, if a tree grows higher than its neighbors, it starts a chain reaction, where all of the neighboring trees try to grow higher as well, resulting in the canopy effect you mention.

All trees have certain height that they grow to. It might be just a coincident that all of them look the same height.

Why do all people stop growing at around the same level?

They don't--you're seeing the canopy--some of the bigger trees have grown up and filled in over the others.

ITS AN OPTICAL ILLUSION....DUE TO DISTANCE
