""a lot more environmentally friendly than the gas pipeline to tide water.....""
AK-made Flexpipe can easily carry 5bcfd of NatGas to market, and do it with much smaller enviro-footprint. 
AKFlexpipe system can be installed with moving only 2% of the soils/gravel required to build the big steel megapipe. No access roads are required. It's easy to install thru swampy or permafrost lands. In areas where you need ZERO surface disturbance, 20-mile sections of AKFlex can be easily microtunneled/HDD with little added cost per mile compared to trenching.

Here's how to install a utilidor tunnel under the Yukon River in Sightas shoal 2000' downstream from the haulroad bridge.

This is a method I knew about 10 years ago, but the "experts" fooled AKLNG/AGDC into thinking a goofy expensive suspension bridge was "the best".
