Downtown Kansas City is the central business district (CBD) of Kansas City, Missouri and the Kansas City metropolitan area.
 It is between the Missouri River in the north, to 31st Street in the south; and from the Kansas–Missouri state line east to Bruce R. Watkins Drive as defined by the Downtown Council of Kansas City; the 2010 Greater Downtown Area Plan formulated by the City of Kansas City defines the Greater Downtown Area to be the city limits of North Kansas City and Missouri to the north, the Kansas–Missouri state line to the west, 31st Street to the south and Woodland Avenue to the east.
 However, the definition used by the Downtown Council is the most commonly accepted.
Kansas City Scout is one of the United States' largest electronic traffic management systems.
 It was created in 2000 as part of a bi-state initiative between the Missouri Department of Transportation and the Kansas Department of Transportation to provide this system for the Kansas City Metropolitan Area, which is in both Missouri and Kansas (the anchor city of Kansas City is in Missouri).
 The project's cost was $43 million.
 Of that amount, the Federal Highway Administration (FHWA) contributed 80-90 percent of the project cost.
 KDOT and MoDOT shared the remaining cost.
 The system employs a system of electronic boards placed on major highways throughout the metropolitan area that display traffic information whenever information needs to be displayed (due to an accident, lane closure, highway closure etc.), and the system also has cameras on those billboards to automatically detect traffic problems.
 While the system has extensive coverage of highways in the Kansas City Metropolitan Area it still has much more to cover.
 Since it would be too expensive to cover all the major highways in the Kansas City metro (which has more miles of highway per person than any other metropolitan area in the United States), studies were conducted to determine which highways or segments of highways have priority due to higher accident rates.
 Since the project's beginning, it has expanded greatly, and will continue to expand.
 Future plans are to extend coverage to I-635 and cover I-435 even more (especially in the northern areas of the metro) as well as other major city highways.
 It was named after the iconic Kansas City Scout Statue that exists in Penn Valley Park, overlooking Downtown Kansas City.
