Again, the wikipedia article that you linked points to a preposterous insufficiency in our ability to maintain infrastructure:

"[...] On February 26, 2014, in the wake of another suicide from the bridge, independent Rep. Joe Brooks of Winterport proposed emergency legislation to the Maine Legislature to require the installation of a suicide barrier on the bridge.[22] This proposal was rejected due to cost, as a barrier was estimated to cost between $500,000 and $1 million, plus additional costs for regular inspections. As an alternative, two solar-powered phones were installed on each end of the bridge in May 2015 which connect users to a suicide hotline. The phones cost $30,000. State officials were aware of instances the phones were not functional, and increased inspections of them to weekly from the previous monthly. They could not determine if the phones were functional when a March 5, 2017 suicide, the first since the phones were installed, occurred. The phones were found to be out of order on June 23, 2017, when an abandoned car on the bridge resulted in a search of the Penobscot River by authorities looking for its driver.[7] The emergency phones on the Penobscot Narrows Bridge were reported out of order following another suicide in 2021.[9][23] They were subsequently replaced.[24] In May 2022, the Maine legislature was reportedly planning to "pull together a study group on suicides by bridge."[25] Funding was subsequently approved for a barrier, but the installation slated for 2024 was delayed for further testing..."

Why are our systems like this? There is no culture of accountability, for one. There is also no desire to dream big, anymore, it seems.

Why is everything so expensive when it's paid by the State?

>non I-95 route up through Maine to Bar Harbor / Acadia National Park.

Which basically means that that whole bit of $$ producing tourism infra is that much closer to everything south.
