It is a residential road that people use to bypass Broadway as B’way is congested. Other parallel roads have stop signs. This road does not. It is wider and has a dotted yellow line to allow passing, but beware: marked and unmarked NYPD cars from the 50th precinct sit on "donut break" to catch anyone going over 30mph. It you move 30mph you are fine as you should be happy you are traveling with out stopping/starting, but the nature of congestion in The Bronx lulls you into a sense of "hey I can go faster here" mentality. Simply put: Don’t. The 50th uses Irwin Ave. to feed the payroll of New York City’s inflated budget, although you shouldn’t be speeding anyway. This post is to try and make things safer for all of us.
