Road expansions refer to the process of widening existing roads or adding new lanes to improve traffic flow and accommodate increasing vehicle numbers. This can involve construction work that enhances safety and reduces congestion, making travel more efficient for commuters and freight transport. These projects often include the addition of features like bike lanes, sidewalks, and traffic signals to support various modes of transportation. Road expansions can also lead to economic benefits by improving access to businesses and reducing travel times for residents, ultimately contributing to the overall development of the surrounding area.
