There's a new bike/ped bridge along the MUP over the busiest street I have to cross. I used to take a street route which was fun and safe but I'd sometimes have to wait a long time at this one intersection, now I have ZERO stoplights thanks to this bridge and my new route that follows the MUP instead of the street. And it's fun to look down on all the slow moving traffic below too.
It's also fun to do some fixie skids on downhill side.
