Yes, that is also what I've read. I found an older (non-pay-walled)article
https://www.politico.com/news/2023/12/05/congress-ev-chargers-billions-00129996"States and the charger industry blame the delays mostly on the labyrinth of new contracting and performance requirements they have to navigate to receive federal funds. While federal officials have authorized more than $2 billion of the funds to be sent to states, fewer than half of states have even started to take bids from contractors to build the chargers — let alone begin construction."
and
"The bulk of the infrastructure law funds, $5 billion, are dedicated to building fast chargers along interstate highways under the National Electric Vehicle Infrastructure program. The program requires the chargers meet a strict set of standards, such as being built at least every 50 miles over major routes, being operational at least 97 percent of the time and featuring credit card readers for easy payment."
