Did Detroit prosper from its Port Activity 2017 ?

[O3H]

Detroit is on the river, so "having" a port is a no brainer.
Effectively making economic gains year after year is a bit tougher

GM’s interest was enhanced due to the decision by the
vessel operator Spliethoff, a Dutch based ocean carrier
offering container service between the Great Lakes and Northern Europe,
to increase its service offering to the Great Lakes.

"Port Authorities play a critical part and economic
development role through the issuance of bonds
to finance facility development.
Unfortunately, in the State of Michigan, State law limits the Port bond financing to “facilities owned by a Port Authority”.
This has stymied the ability of the Agency to assist private
terminals in the Detroit area.
In order to remedy this situation, the Port Authority in 2015
began working with the Michigan House Commerce and Trade Committee on modification to the Port Authority Act to address this limitation."
