This Maine relic is truly amazing! 

So apparently way back in the day there were bridges built that required someone with good strength to crank manually to open for boats to come thru. And, there is one of the oldest one's in the US right here in Maine.

This bridge is called a pony truss swing bridge,it is 86 years old and it's named Trevett Bridge. A woman by the name of Terry Freese has been the operator of this bridge for many years. This bridge connects Barters Island to Hodgdon Island. It is quite amazing to see the process done! Unfortunately, according to this NBC Nightly News video the bridge is soon to be modernized by 2020. No more hand cranking anymore, it turn by the push of a button.

Have you seen this bridge before in person?
