Here is the definition of
Boulevard from Wikipedia:
Boulevard (French, from Dutch: Bolwerk – bolwark, meaning bastion) has several generally accepted meanings. It was first introduced in the French language in 1435 as boloard and has since been altered into boulevard.
In this case, as a type of road, a boulevard (often abbreviated Blvd) is usually a wide, multi-lane arterial thoroughfare, divided with a median down the center, and "roads" along each side designed as slow travel and parking lanes and for bicycle and pedestrian usage, often with an above-average quality of landscaping and scenery. The division into peripheral roads for local use and a central main thoroughfare for regional traffic is a principal feature of the boulevard. Larger and busier boulevards usually feature a median.
Not meaning to start a tiff, and it isn't my intention, but I did live in Salt Lake for many years and the only street anywhere near Downtown or the city that I would classify as a Boulevard is Foothill Boulevard. The only street downtown that would come close, and still isn't technically a Boulevard is South Temple street.
Most streets downtown Salt Lake lacked and still lack (I have a little sis in Tooele and visit on occasion) above average landscaping. A good example of a "Boulevard" is Capitol Boulevard here in Boise which has above average landscaping and bike lanes, trees separating most of the sidewalks from the street, and the way the Boulevard forks in front of the statehouse. The Boulevard is framed by the Depot on the Bench on the South side and the Capitol Building on the North side.
Park Center Boulevard is another excellent example with extreme -above average landscaping, landcaped median strips, also there is Harrison Boulevard, and a few others scattered around Boise.
So, which streets are you considering Boulevards in downtown SLC? Especially ones considered "iconic" or in your opinion "iconic"--- Just curious. Have some of the streets added landscaping and grass in the last year? State Street has the potential to become a true Boulevard much like Capitol Blvd here in Boise. North Temple could even join in on the action.
