Gateway Arch FundingProject Funding

CityArchRiver is a public-private partnership formed to fund and coordinate the design and construction of a complete renovation of the Gateway Arch grounds and its surroundings.  Private donors funded the entire cost of the international design competition, Framing a Modern Masterpiece: The City + The Arch + The River, and continue to fund design costs for the project.

Construction of the $380 million project is funded in three ways:

  • $69 million - Public funds from federal, state and local sources such as a USDOT TIGER grant, MoDOT funds, other federal grants and funding from Great Rivers Greenway District
  • $90 million - Proposition P bond proceeds - On April 2, 2013 voters in St. Louis County and St. Louis City approved Proposition P: The Safe and Accessible Arch and Public Parks initiative. Great Rivers Greenway is the steward of the taxpayers’ investment in the project.
  • $221 million -  Private funding from gifts, grants and donations raised by the CityArchRiver Foundation. The Foundation will raise another $29 million to seed an endowment that will help maintain and improve the project area into the future.
