For example, there is a router operated by Telia (AS1299) in Chicago
that has a high concentration of such links.
this doesn't appear to match 1299's public network topology:

Is ttl decrement disabled on the test paths you're measuring?
Broadly speaking, if you have a point-to-point link from one location to
another (or parallel set of links with a common failure path, e.g. waves
on a specific fibre path), there's a single router at each end.
