Feedback for the D.C. Government

I love that D.C. sends alerts to my phone and e-mail account. I just wish they didn't seem like they were written by someone without any education. From today:

DDOT reports at 295 Southbound  there’s a two vehicle accident with injuries all lanes are block at this time and all on coming traffic is Being rerouted on to East Capitol St.

If I were grading this in English class, I'd mark seven problems with this short message. Can you find them?
