CHICAGO — Hundreds of bicycle advocates were at an annual summit this month in Washington, D.C., when their cellphones lit up over breakfast with an urgent email warning that President Donald Trump’s transportation department had just halted federal grant funding for bike lanes. As the administration targets green energy projects championed by former President Joe Biden that boosted transit, recreational trails and bicycle infrastructure, several states are banding together to advance those priorities on their own. California, Illinois, Maryland, Michigan, Minnesota, New York and Pennsylvania joined forces for a national organizing effort dubbed the Clean Rides Network. The group gained momentum in various statehouses this year on environmentally friendly transportation projects it contends the federal government has abandoned. “These are changes we need to make anyway, but they’re more urgent than ever,” said Justin Balik, senior state program director for the environmental advocacy group Evergreen Action and one of the organizers of the Clean Rides Network. “I’ve been calling the state departments of transportation the next frontier of climate advocacy.”
