City streets
Most of Denver has a straightforward street grid oriented to the four cardinal directions. Blocks are usually identified in hundreds from the median streets, identified as "00", which are Broadway (the east–west median, running north–south) and Ellsworth Avenue (the north–south median, running east–west). Colfax Avenue, the major east-west artery through Denver, is 15 blocks (1500) north of the median. Avenues north of Ellsworth are numbered (with the exception of Colfax Avenue and a few others), while avenues south of Ellsworth are named.
There is also an older downtown grid system that was designed to be parallel to the confluence of the South Platte River and Cherry Creek. Most of the streets downtown and in LoDo run northeast-southwest and northwest-southeast. This system has an unplanned benefit for snow removal; if the streets were in a normal N-S/E-W grid, only the N-S streets would receive sunlight. With the grid oriented to the diagonal directions, the NW-SE streets receive sunlight to melt snow in the morning and the NE-SW streets receive it in the afternoon. This idea was from Henry Brown the founder of the Brown Palace Hotel. There is now a plaque across the street from the Brown Palace Hotel which honors this idea. The NW-SE streets are numbered, while the NE-SW streets are named. The named streets start at the intersection of Colfax Avenue and Broadway with the block-long Cheyenne Place. The numbered streets start underneath the Colfax and I-25 viaducts. There are 27 named and 44 numbered streets on this grid. There are also a few vestiges of the old grid system in the normal grid, such as Park Avenue, Morrison Road, and Speer Boulevard.
All roads in the downtown grid system are streets. (16th Street, Stout Street) Roads outside of that system that travel east/west are given the suffix "avenue" and those that head north and south are given the "street" suffix. (Example, Colfax Avenue, Lincoln Street,). Boulevards are higher capacity streets and will travel any direction (more commonly North and South). Smaller roads are sometimes referred to as places, drives or courts. Most streets outside of the area between Broadway and Colorado Boulevard are organized alphabetically from the city's center.
Confusion may arise where the two grid systems meet, especially given downtown Denver's one way streets. The system can be easily navigated with the help of directional signs. The mountains to the west also offer a great compass-point for those attempting to drive in the Mile High City.
