Highway projects involve the planning, design, construction, and maintenance of roadways and transportation infrastructure, including highways, freeways, and interstates. These projects aim to improve transportation efficiency, safety, and accessibility for motorists, cyclists, and pedestrians. Highway projects may include widening existing roads, constructing new roads, bridges, interchanges, and rest areas, as well as implementing traffic management systems, signage, and lighting. These projects are typically carried out by government agencies or private contractors and require collaboration between engineers, urban planners, environmental specialists, and other professionals to ensure the successful completion of the project.
