Road closures occur when a street or highway is temporarily shut off to traffic. This can happen for various reasons, including construction, maintenance, accidents, or special events. Authorities often post signs and barriers to inform drivers about the closure and provide alternative routes. During a road closure, it is important for drivers to follow detour signs and instructions from local law enforcement. This helps ensure safety for both motorists and workers. Road closures can also affect public transportation, as buses may need to change their routes to accommodate the blocked roads.
