Traffic isn't directed to a router IP. IP addresses are end-to-end (putting aside things like NAT and tunneling.) ISPs look at destination IP addresses and routing tables to determine how to route. (The reason you see router IP addresses with traceroute is because of the way traceroute works, depending on router's to send back an ICMP TTL Exceeded message.) In the U.S., we see stuff like this a lot. I could traceroute a server I know is a few miles down the road and the packets might go all over the U.S. before ending up down the road.
