On behalf of the mayors and city transportation officials who manage the streets, transit networks, and infrastructure that millions of Americans use every day, we write to offer our perspectives on the positive changes made by the BUILD America 250 Act as well as key changes to the bill we hope to see as Congress continues work on a long-term surface transportation reauthorization. While we welcome the continued federal investment and partnership, we believe a long-term federal reauthorization of our nation’s surface transportation programs should do more than extend or consolidate existing programs; it should position American cities—the heart of our economy–to meet the transportation challenges of today, tomorrow, and future generations.
