The Baltimore Washington suburban corridor in central Maryland has changed dramatically over the last few decades. The 30 mile stretch along I-95 connecting the two cities has become one of the most densely developed and populated areas in the entire country. This intense suburbanization has generated a massive volume of vehicle traffic and transformed the roadways in central Maryland.
Columbia in Howard County is one of the areas in the Baltimore Washington corridor that has undergone the most dramatic change during this period. In the early 1990s, Columbia was still felt like the isolated “planned community” that it was originally designed to be.
Today, however, Columbia is the second largest town in Maryland with a population of well over 100,000. The volume of vehicle traffic and nature of the roadways in Columbia have followed a similar pattern of development. What used to be single-lane roads with stop signs have evolved into 4 or even 6 lanes commercial routes clogged with traffic lights.
