Perhaps it would cost effective to do three short 500M 60-80GHz hops over the freeways and railroad tracks with fiber underground through the open space between them? At that point it might just be better to go through the paperwork headache of boring all the way through. I know a guy in Los Angeles who likes digging tunnels.

There are ways to achieve 6 Gbps full duplex using multiple parallel 18 GHz (80 MHz) dual polarity links, if you could coordinate enough high/low frequency pairs on the path. It would be a number of dishes and radios. Or some combination of 11 GHz/80 MHz channel/dual polarity links and several 18 GHz/80MHz channel/dual polarity links. I would not recommend trying to aggregate such together at L2 due to slightly different performance of different radios and polarities on the same path. Aggregated together at L3 by having multiple OSPF equal cost links between two routers, one on each end, so that the traffic flows between 1GbE router interfaces were distributed equally. There are 10 Gbps 71-86 GHz band radios now. Distances are good for like, 2 miles at high reliability, not much more.

Fiber would require traversing 2 state highways and a railroad track, so there is that.
