Allen and Northline is one of the worst intersections in all of downriver....
Take Fort Street if you are going North or South between Detroit and Gibraltar.... it is 2 lanes at minimum, and 3 lanes for most of the length. Watch out in Southgate though, slows down to 35 mph and Southgate cops suck. 45 mph from Eureka to sibley. 50 mph from sibley til it ends.
Pennsylvania road for East/West..... less traffic than Eureka or Sibley. only a 2 lane road.... but nothing really on it once you go west of telegraph. I've hit up to 150 mph on Pennsylvania when I used to have my gsx-r 750 (but you can go fast anywhere on a bike)
