Massachusetts Tax Dollars Hard At Work

Would somebody please explain to me why the MA DOT painted SOLID white lines at the on/off ramps on 128, painted over them, then put dots down?!?

Here they are once they were painted over:

solid on ramp 111615


Here are the new dotted lines that should have been there in the first place:

dotted on ramp 111715

A fine use of our tax dollars!!
