In some cases existing buildings or facilities may be linked to the infrastructure investment. By commercializing these assets, government addresses the challenge of disused or underused assets and creates new revenue streams at the same time.

Infrastructure projects can attract additional revenues through retail services, provided in, above, under, or around the infrastructure facility, e.g. convenience stores, shops, banking services and floating or rooftop solar. 

Hotels, restaurants, cafes, catering, and other hospitality and tourism facilities can bring significant revenues for infrastructure. These commercial activities are particularly profitable when located near or associated with locations or facilities that attract crowds.

The space above, below, and around the infrastructure can be used for commercial parking facilities, to earn new revenues and to address congestion.

The space in and around an infrastructure project can be used for advertising and marketing, to draw attention from consumers and increase consumption of their products or services. 

Advertising is a well-established business segment for operators of public transit stations, terminals, and airports. High footfall areas within public transit are perfect locations to promote a product, service, or cause and are effective customer touchpoints for brands. Communities in high-mobility cities often regard advertising in public transit stations as quick reflections of what is in the market.
