The U.S. Department of Transportation has approved a $146 million federal grant for the Grand Avenue corridor project in Phoenix, aimed at improving a key transportation hub. This funding is part of a larger $356.6 million effort to address traffic issues at the complex six-legged intersection, which includes two at-grade railroad crossings. The money comes from the Infrastructure Investment and Jobs Act, with $133.9 million from the INFRA grants program and an additional $12.7 million from the Mega grants program.
