Just a reminder to do and effectuate access planning before major transportation infrastructure opens: Peru's airport

 According to Bloomberg, "Nice Airport, If You Can Get to It: No Subway, No Highway, No Bridge," Lima Peru is getting a new airport without roadways to it--they are planning to cross a river with temporary bridges and no transit.  From the article:

A highway meant to whisk travelers to the $2 billion terminal has yet to be built, even though flights are supposed to begin operating in just seven weeks. A bridge to get across a river that runs along the grounds was never constructed. There’s a subway stop labeled “Airport” planned for Lima’s new metro system, but that station is set to be built (three years from now) much closer to the old airport that’s being decommissioned.

“Having a subway station named ‘Airport’ where there won’t be an airport anymore — it’s just the most graphic example of our lack of planning as a nation,” said Carlos Gutierrez, the head of Peru’s airline industry trade association.

... The bridges will get private cars from congested side roads into the terminal, but there’s no bus service currently scheduled, and there’s no room to allow pedestrians to walk across. That’s a problem for the airport’s 17,000 workers, most of whom now arrive at the existing terminal via public transportation. And officials are worried about the safety of travelers forced to navigate the traffic-choked streets in the crime-filled neighborhood that surrounds the airport.

I do think airport mobility planning in the US can be weak.  It was abetted for years by a rule by the Federal Aviation Administration that airports couldn't pay into existing transit systems that also serve non-airport riders.  Fortunately, the Biden Administration dropped that rule.  But it still affects airports like LaGuardia, Newark, JFK, and Philadelphia.

... US airports with decent transit like Cleveland or National in DC are connected through the largesse of local authorities.

-- "To and from origin stations can be difficult: More on the Silver Line and intra-neighborhood transit (tertiary network)," (2022) -- links to many past entries

Although lack of access planning for regular transit stations is an issue too.  In Baltimore it was an issue with the Lutherville light rail station. In DC, with the NoMA station among others ("Revisiting creating Public Improvement Districts in transit station catchment areas," 2020).
