My first choice for that spot would be Green Giant Arborvitae, IF you are okay with them planted closer to the house rather than closer to the road, due to their intolerance to salt spray. You could also benefit from a seasonal burlap shield (Set well away from the foliage of the trees) between the trees and the road. These trees would be tolerant of more moist conditions, clay soil, etc, and are very fast growing and disease resistant. Here is more information about this tree:

If you do not want to plant closer to the house, I have a list of trees that are more salt tolerant. You would need to look at the needs of each type of tree to see how it matches up to your site conditions.

I would stay away from Jack pine, Austrian pine and Colorado Blue Spruce. Juniper or red cedar might be the best choices in this case.
The trees that are there now would need to be removed- they have a fungal needle cast disease that is not easily treated. (probably Colorado blue spruce).
I hope this is helpful.
Thank you for contacting Ask Extension.
