CBS Radio: Metro Buses Overcrowded on 16th Street:   “Anyone who watches 16th Street rush hour traffic can very quickly tell that buses get held up by traffic to a terrible degree,” says Putta.  “And they’re carrying so many commuters who could be getting to work 15-20 minutes faster if they had their own lane.  “Only 3 percent of all the traffic on 16th Street is buses, but they carry more than 50 percent of all the people that travel on 16th Street,”
