In general, mail from Missouri will first be transported to a regional distribution center, where it will be sorted and processed. From there, it will be loaded onto a truck or train and transported to a distribution center in Colorado Springs. Once it arrives in Colorado Springs, it will be sorted again and delivered to individual addresses by postal carriers.
The exact time it takes for mail to travel from Missouri to Colorado Springs can vary depending on the specific route and the time of year. However, in most cases, mail will arrive within 2-3 business days.
