Map on left shows DART's light rail system. The highlighted alignment (purple and yellow) is the Red line that follows the North Central Expressway corridor.
DART's light rail system is one of the most successful systems in the country. Regarding the North Central Expressway corridor the Red line actually adds the capacity equivalent to two highway lanes.
The brilliant concept about locating the Red line along North Central Expressway is the easy option that drivers have to get off the highway and park & ride DART into downtown.
The option to use light rail has proven to have many benefits over driving a car into downtown such as: scheduled light rail routes are fixed and are not affected by traffic delays or accidents, allows to relax and/or free time to read, and the cost of the ride is minimal in comparison to the cost of parking downtown.
