Community Transit Enviro 500 10811 in downtown Seattle, WA. Community Transit operates several commuter express routes into and out of Downtown Seattle on weekdays, and this is one of the 'Double Tall' buses that can be seen on such runs to and from the northern suburbs of Seattle.
I would not have thought that these would be any kind of practical in Seattle with all of the bridges to be found there. Not to mention the low-hanging electric and communication wires.
Yeah... but somehow they defy belief and continue to run into and out of Downtown Seattle at Rush Hour. They're only 3 feet taller than the New Flyer artics that have run there for decades though.
