It serves that purpose - but I believe it was justified as a defense project than a way to deliver mail. I could be wrong but I don't think we've had any road infrastructure built specifically for moving mail in a very long time, although that happened in the past.
Wikipedia says in 1838 they passed a law designating all current and future railroads as post roads, so it sounds like all the railroad network is.

The postal system seems so obsolete to me. Important papers/checks being delivered and taken away from box by the road. Right like I would still do thatGas powered cars driving from house to house to deliver stuff, when they for the most part could make one stop even on a designated corner for all. Daily trips to each home. Seems like in todays world what does still arrive could be delivered every few days. The rest could be run like UPS or FedEX.
Post service same as a news"paper",obsolete .
I can't remember the last time I put a check for a bill in the mail box. I am lucky the few that ever do arrive like property taxes, sewer bill, I just bike it up and pay. My 80+year old mom, will put a check in the box and wait to make sure it gets picked up. Like it is now is safe hands after it leaves her box.
Kind of hard to send a physical object through the Internet.except....

My father was a systems accountant for the air force for nearly 30 years until he retired 20 years ago. During that time he was part of a committee that was tasked with figuring out how to pay employees scattered around the world, some in places that may not have much bank infrastructure, and whose families may be located elsewhere and need access to the employee's paycheck. The system they came up with was direct deposit. Up until a couple of years ago when the government forced him to begin using it for his pension he absolutely refused to use it. Somehow he felt that the 'realness' of a physical check was better and more reliable then an invisible money transfer into his account.
Another reason to keep the P.O. around is the popularity of their new campaign "if it fits, it ships" using the free boxes the P.O. provides.
Some friends who used to use UPS or FedEx switched to the P.O. and claim it's much cheaper.
