The main purpose of this legislation is to update and extend the provisions of the Rural Electrification Act of 1936, specifically to support the development of middle mile infrastructure in rural areas. This infrastructure is crucial for improving internet access and connectivity in less populated regions, which often lack adequate service. The key provision of this legislation is the reauthorization of funding and support for middle mile infrastructure projects. It changes the timeline for these projects from the years 2018 through 2023 to a new period from 2026 through 2031.
