Widening a freeway or street, or adding a new road is a traditional strategy to ease traffic flow problems. Though this technique is not a panacea for congestion, it may be an appropriate course of action when the existing road cannot handle the travel demand, and less expensive options cannot address the challenges. New or widened roads can serve as a relief route or economic catalyst in the region. In any case, these are major projects that require careful planning, environmental consideration, comprehensive public engagement, and financial support.
