The United States Census Bureau estimates that in 2007 the population of the City of Colorado Springs was 376,427(47th most populous U.S. city), the population of the Colorado Springs Metropolitan Statistical Area was 609,096 (84th most populous MSA), and the population of the Front Range Urban Corridor was 4,166,855. Pikes Peak towers over the city.Today, Colorado Springs has many features of a modern urban area, such as parks, bike trails, urban open-area spaces, business and commerce, theatres and other entertainment. It was first established as a posh resort community, though the older mining supply center of Colorado City (now Old Colorado City) was merged later, and the tourist industry has remained strong and offers many activities and attractions. In July 2006, Money magazine ranked Colorado Springs the best place to live in the big city category, which includes cities with 300,000 or more people. Colorado Springs is not exempt from the problems that typically plague cities that experience tremendous growth: overcrowded roads and highways, crime, sprawl, and government budget issues. Many of the problems are indirectly or directly caused by the city’s difficulty in coping with the large population growth experienced in the last 20 years and the annexing of the Banning Lewis Ranch area for 175,000 future residents. In 2004, the voters of Colorado Springs and El Paso County established the Pikes Peak Rural Transportation Authority and adopted a 1% sales tax dedicated to improving the region's transportation infrastructure. Together with state funding for the Colorado Springs Metro Interstate Expansion (COSMIX)(2007 completion) and the I-25 interchange with Highway 16 (2008 completion), significant progress has been made since 2003 in addressing the transportation needs of the area. Currently the City is trying to overcome a $23.3 million budget gap created by falling sales taxes and rising expenses.
