Demontrations are announced on the Champ de Mars on Saturday 24th November 2018. This situation prevents us to welcome our visitors under optimal safety conditions. Therefore the SETE (Société d’Exploitation de la tour Eiffel) has decided to close the monument to the public all day. To all our visitors who bought online tickets for a visit on the 24th November: with no necessary action from your part, your tickets will be fully cancelled and refunded onto the bank card that was used during the online purchase.
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 that 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. Larimer Street, named after William Larimer, Jr., the founder of Denver, which is in the heart of LoDo, is the oldest street in Denver.
