(1) the traffic that blocked went well again.
(2)"You'd better pay the wage, or I'll dismiss your licence."
(3)"The wage has been delayed to pay me for a year, and my boss doesn't want to give me!"

(1) The traffic that had been jammed began to flow again. [NOT SURE I UNDERSTAND YOUR ORIGINAL VERB TENSES, JOBB]

(2)"You'd better pay the wages, or I'll rescind your licence."

(3)"My wages have not been paid for a year, and my boss doesn't want to give me them!" (or, 'give them to me')

PS. the head of a city is called mayor, and the head of a county is called what?

It varies. I think 'County Supervisor' is one; another is 'County Commissioner'. The latter is usually one of a Board of Commissioners, and the head is, I believe, the 'Chief County Commissioner'.
