Beta version with possibility to use bridges as connections

Aug 05, 2026

There is the beta version of UndergroundTransport V6.1.1 It adds the option to use the UT entities to use bridges as connections. I don't expect any compatibility issues with current V5.3.1 version. Is using it, beware that the transport duration between the UT entities is dependent on the distance between them. Bridges tend to be long, so it takes time before the products reach the receiving UT. I have it here on discord as the COI hub doesn't has the possibility to have two version (current an future beta) simultaneously active
