I found broadband is mentioned on three pages in the infrastructure document, Page 8, 9, and 15.
Page 8 Establishment of Transformative Projects Program
Infrastructure sectors covered by this program could include, but would not be limited to, the transportation, clean water, drinking water, energy, commercial space, and broadband sectors.
Page 9 Applications and Evaluation Criteria for Rural Performance Grants
For specific sectors, a State also would demonstrate other criteria the administering agency determines appropriate consistent with this program, including increased broadband availability and investment.

It will up to the States to allocate funding to the specific projects. With no specific set-aside, broadband will have to compete with other infrastructure projects.
One note, this is just the opening round of the negotiation cycle.
