Thank you for your question. Will you please take a full tree picture of your blue spruce trees and send them to me?  Thanks. 

Thank you for contacting us regarding your Blue Spruce issues.

There are 3 fungal pathogens that affect spruce trees:
1. Spruce Needle Cast
2. Tip Blights 
3. Canker diseases

Based on your pictures, it appears the fungus is affecting older growth and you still have growth on the current year's growth.   It is not affecting the tips, which rules out #2 above and I don't see any white resin coming out of the branches or stems ruling out #3.   I do see lichens which typically do not impact the tree.

There are a couple of insects that affect spruces too, but I don't think that is your issue.

Spruce needle cast or Rhizosphaera needle cast is a foliar disease that usually appears late spring to early summer.  Last years needles turn purple-yellow- brown and then drop off in the fall.  Trees infected for a number of years can only contain this year's growth at the tips.  Branches eventually die typically starting from lower branches moving up.  Can be more prominent on the north side of the tree.  Black fruiting bodies can be seen running up and down the needles on the new growth.  I've included a picture in one of the attachments. It can take up to 15 months for the needles to show visible symptoms after the initial infection. Young trees may be killed by this disease, but usually branches die off after 3-4 consecutive years of defoliation, causing trees to look disfigured.

Drought conditions like we have had this year in some of Ohio can make the situation worse.  You should give some water to plants in these times.

Early identification of Rhizosphaera can prevent major damage to individual trees and prevent the spread to nearby trees. Protecting new growth as it emerges is very important. For best effectiveness, fungicides should be applied when the emerging needles are half elongated (1/2 to 2 inches in length). Needle cast diseases can be effectively controlled with fungicides containing chlorothalonil. For Rhizosphaera needle cast, two properly-timed applications per year for at least two consecutive years, and sometimes three years, is required for control. Heavily infected trees may require several years of fungicide applications but should be sprayed, soil drenches are not effective. Also, clean-up of any infected needles and branches will help reduce the spread of the disease.

Since you will never get new growth on the entire branches in future years, only on the tips, it is questionable whether you want to continue to have these trees in your landscape.   That is a personal decision though.  Depends on how much tolerance you have for the look.   

The other 2 trees you sent me appear to have symptoms as well.

I have attached a couple fact sheets to read that tells about this disease and the other spruce diseases.

Let me know if you have other questions and good luck with your decisions moving forward.

You are welcome.  
Also I caution you that trees and shrubs close to the road and suffer from salt damage.  
I don’t know how close they are or if it there is large amount of salt but just be aware of that.
