The DNA corridor is about 13 miles in length from downtown Sacramento to the Sacramento International Airport. The area studied for planning the DNA Corridor includes most of downtown Sacramento, South Natomas, North Natomas, Metro Air Park and the entire Sacramento International Airport property. While the southern boundary of the study area for transit improvements was the Sacramento Valley Station located at 5th and I streets, for environmental analysis and travel demand modeling purposes, a larger portion of downtown was analyzed. The expanded southern boundary followed R Street (west of 11th Street), N Street and Capitol Avenue between 15th Street to Alhambra Boulevard. The eastern boundary was set as the Natomas East Main Drainage Canal, Route 160, Business 80 and Alhambra Boulevard. Elkhorn Boulevard served as the Northern boundary of the study area, with the exception of the section of Airport property that is bounded to the north by Elverta Road. The western boundary of the study area included the western edge of Airport property, Bayou Slough, Power Line Road, Del Paso Road, the Natomas West Main Drainage Canal, the Natomas Main Drainage Canal and the Sacramento River.
The alignment for the LPA starts in downtown Sacramento and proceeds past the Sacramento Valley Station and through the Railyards area. The alignment continues north through South Natomas and into North Natomas, passing Arco Arena to the North Natomas Town Center. At the Town Center, the alignment shifts to the west and continues northwest to the Metro Air Park development and the Sacramento International Airport.
