PHOENIX • U.S. transportation officials announced $2.2 billion for local infrastructure projects on Thursday, paving the way for new bridges, roads, bike lanes, railways and ports in scores of communities across the country.

The competitive grants are more than double the amount awarded the previous year under the same program. The influx comes from a $1 trillion infrastructure law backed by President Joe Biden, which provided an additional $7.5 billion over five years for the grants.

Transportation Secretary Pete Buttigieg said the projects would help modernize America’s transportation systems.

“This is a program that recognizes many of the most interesting and compelling ideas and designs and plans aren’t going to come from Washington, but more of the funding should,” Buttigieg said. “That’s what we’re delivering here.”

Buttigieg traveled to Arizona to highlight projects in Phoenix and Tucson, each of which are receiving the maximum $25 million. In Phoenix, the money will help build a new bike and pedestrian bridge over the Rio Salado, connecting the city’s southern area with downtown.

In Tucson, the money will revamp a prominent street and replace a 1960s-era vehicle bridge that’s in poor condition. It also will add a separate bicycle and pedestrian bridge as part of what Mayor Regina Romero called “a transformative investment in Tucson’s infrastructure.”

Other newly announced projects in the Rebuilding American Infrastructure with Sustainability and Equity program also provide funding for bicycle and pedestrian paths.

Texas and Kansas are each receiving about $25 million for hiking and biking trails. Huntsville, Alabama, is getting $20 million to improve a pedestrian corridor linking downtown to isolated neighborhoods. Another $20 million is helping finance a new bike and pedestrian bridge over the Potomac River between Arlington, Virginia, and Washington, D.C.

Though still substantial, the funding doesn’t have quite the buying power as anticipated when the infrastructure legislation passed Congress last year. That’s because inflation has driven up the cost of key transportation construction materials, such as steel plates for bridges and asphalt for paving roads.
