Become a CLEC. Or, more appropriately, I suppose: look into the benefits that being a CLEC would give you (in this regard) and consider if that's worth it for you.
You don't have to be a CLEC to access right of way, including ducts and poles. It's enough to be a BIAS (Broadband Interner Access Provider), which you already are.
Becoming a CLEC does classify you as a "utility" though, which has other benefits.
Which benefits do you need that a CLEC has but a BIAS does not?
