Contruction Trucks Using R st. Alley as passway

So I am all for making it easier on the construction trucks/dump trucks to get to whatever they are doing at McKinley Technical High School football field to have it done faster. As this has been going on week after week for the entire summer. Once school starts back up in 2 weeks there is going to be a problem since almost 1/2 of the kids that go to Emery Elementary, walk without parents to and from school The dump trucks don't seem to stop when they reach intersection of 1st N.E. and R alley N.E. Not to mention that most of the students of McKinley Technical High School that drive use that alley to get to and from school too while talking on their cell phones. I'm just afraid that most of them will not be paying attention and there will be an accident, as there almost was this past spring every time two cars come to 1st street NE and R street alley NE. So I will be making calls to the mayors office everyday once school starts back up, about why the trucks can not use the actually entrance to McKinley Technical High School on T street N.E. and about how unsafe the drivers of the trucks are.

R street ne, an alley or a street?

So within the pass 15 mins there has been 4 cars that speed down R street ne alley(between lincoln and 1st ne) like its R street, now the reason why its pissing me off so much is the fact that is not a street and should not be used to pass the light at Lincoln and R n.e. There are homes on R street that the kids play in the alley to stay off the street and other people are in the alley cleaning their cars and such.
