Red maples only grow well in soil that has a pH 4.5 to 6.5.  Yellowing leaves with green veins are a symptom of manganese deficiency caused by high pH soils. Maples are very sensitive to road salt.

You can tell if a tree branch is still alive by scraping off a tiny amount of bark on a branch.  If the layer just under the bark is green then the branch is still alive.  If the layer is brown then the the branch has died.  It has been a very cool spring so the tree may be slow to come out of dormancy. Since the red maple tree is so large it is best to hire a certified arborist if the tree needs to cut down.
