The loop limit of a single line station is 3700 feet on 24 gauge cable. That would be point to point with no bridges. Viking Electronics makes a loop extender that would increase the loop limit to thousands of feet, or you might try search engines for a Proctor 46222 or 224 loop extender.
It's unlikely that the telco will treat your pairs as the loop is probably within specs.
