As Congress moves to make the final votes on the $1 trillion bipartisan infrastructure bill this week, investors looking to gain exposure to that extraordinary amount of spending might want to consider adding an infrastructure-focused exchange-traded fund (ETF) to their portfolio.

Infrastructure ETFs seek to provide exposure to companies that build and maintain major projects and systems, like roads, bridges, water resources, railways, communication networks, and electricity networks. The bipartisan infrastructure bill includes measures for upgrading the nation's transportation (primarily highways and airports), broadband, waterworks, and cybersecurity systems.
