Based on the project maps, most PPP projects in the Public Works Finance database are located entirely in a metropolitan area or in non-metropolitan areas.103 There were six instances in which a project crosses several metropolitan areas or a metropolitan area and non-metropolitan areas. In these cases, the PPP project was allocated to the area in which the majority of the transportation asset lies. Further, to avoid overestimation of PPP projects in the largest metropolitan areas, for cases in which a PPP project is situated in a rather equal manner in a top 100 metropolitan area and a smaller metro area, this study assigned the PPP project to the smaller metropolitan area. There are six cases with mixed spatial identification:
■ The Indiana Toll Road crosses seven counties: two in the Chicago metro area, three in smaller metro areas, and two in non-metro areas. The project value was assigned to the smaller metro areas because the Toll Road crosses the seven counties in fairly equal parts.
■ There are two PPP projects on I-75 in Collier and Lee counties, FL which are in two different metropolitan areas: Cape Coral-Ft Myers, which is a top 100 metro area, and Naples-Marco Island, which is a smaller metro. Based on the project maps, a larger portion of I-75 is located in Lee County; therefore, this study assigns these projects to the Cape-Coral metro.
■ A 1998 PPP project on US 550 (formerly SR 44) in New Mexico crosses three counties, each located in different metro areas: Albuquerque (top 100 metro), Farmington (other metro), and Espanola (non-metro.) Most of the road lies in Sandoval County, and thus the project was assigned to the Albuquerque metro.
■ Triangle Parkway in North Carolina crosses two counties, located in two different metropolitan areas: Raleigh (top 100 metro), and Durham-Chapel Hill (other metro.) Triangle Parkway is part of a larger Triangle Expressway project broken up into three parts: Triangle Parkway, Northern Wake Expressway, and Western Wake Freeway. The Triangle Parkway section lies predominately in Durham-Chapel Hill area and is assigned to that metro.
■ The CPTC 91 Express Lanes in California is a 10-mile project that crosses two counties located in two different metropolitan areas: Riverside and Los Angeles, both top 100 metros. The project was assigned to the Los Angeles metro area, given that most of the project is located in Orange County.
