United Bridge Partners (“UBP”) is an innovative infrastructure investment and operating company focused on solving public infrastructure needs with private capital. UBP develops, builds, owns, and operates private toll bridges across the United States. UBP has an exclusive partnership with the New American Bridges Fund, a $1 billion infrastructure investment fund, which provides the capital to develop and build the Company’s bridge projects. UBP made its first investment in the reconstruction of the South Norfolk Jordan Bridge in 2010. The old Jordan Bridge was originally opened in 1928 and was operated continuously until it was closed to traffic in 2008 due to severe structural deficiencies. In late 2010, the bridge was demolished and by November 2010, UBP began construction of the new bridge. The new Jordan Bridge was completed in October 2012, and the facility was immediately opened to traffic while being owned by UBP. UBP has recently completed its second project, the Cline Avenue Bridge (“CAB”), which crosses the Indiana Harbor Canal in East Chicago, Indiana. The original Cline Avenue Bridge was built in 1982 and operated until it was closed by the Indiana Department of Transportation in 2009. The old bridge was demolished by INDOT in 2012. In 2013, INDOT agreed with UBP to replace the old bridge with a new Cline Avenue Bridge that would be designed, financed, owned, and operated by UBP. CAB officially opened to traffic on December 23, 2020. The UBP team is currently working on additional bridges that are in various stages of development and construction which are all expected to come online over the next couple of years. The Company is based in Denver, CO, with affiliate offices in Foster City, CA. For more information see: www.unitedbridgepartners.com.
