Within the scope of the Night Marathon to be held in Istanbul this weekend, access restrictions will be imposed on many roads.

Significant traffic impacts are anticipated in Istanbul's Sarıyer district this weekend due to a sporting event. As part of the event, certain roads will be completely closed to traffic on 4-5 July, and vehicle access will be diverted to alternative routes. The 'Gece Maratonu Yol Koşusu' (Night Marathon Road Race), organized within the boundaries of Sarıyer district, is planned as a high-participation sporting event. In such organizations, taking extensive road closure measures for participant safety and race flow is considered a standard practice. Authorities continue to inform the public with official statements regarding the issue.

Due to the road closures coinciding with weekend traffic, drivers need to be cautious. The closures, starting on Friday, July 4, are planned to remain effective throughout Saturday, July 5. It is important for residents and drivers making intra-city trips to avoid using these roads to prevent disruptions in their travel plans. The organization, carried out in coordination by Istanbul Metropolitan Municipality and Sarıyer Municipality, may create temporary density in regional traffic. Local administrations are issuing warnings regarding the use of alternative transport lines.

Certain parts of the coastal road and variations in the Sarıyer region are predicted to be among the most critical points to be completely closed to vehicle traffic for the safety of the athletes. The full list of roads on the race route to be closed will be announced by the police department and the municipality. On the streets where the running track passes, vehicle entry will not be allowed at predetermined times, and peripheral roads will be kept open under control. There is a mandatory requirement to update information regarding changes in bus, minibus, and private vehicle routes. These measures, taken in line with Ulaştırma Koordinasyon Merkezi (UKOME) (Transportation Coordination Center) decisions, are expected to be strictly monitored by traffic control units.

The 'Gece Maratonu Yol Koşusu' (Night Marathon Road Race), stated to be held in Sarıyer, is one of the events causing Istanbul to have a dynamic weekend in terms of sports and social life. Sporting events, which increase especially in the summer months, can cause changes in the daily transportation habits of city residents. Citizens are advised to avoid areas in Istanbul that will increase traffic density in order to avoid inconvenience. Extensive security measures need to be taken to meet the logistical needs of the thousands of athletes and spectators attending the race. It is highly likely that there will be possible disruptions and route changes in city public transport services due to road closures.

Due to the planned road closures, it will be beneficial for residents living in the region to pay attention to transition times when traveling to other points of the city. Traffic density is expected to increase, particularly at connection points of closed roads and on alternative routes. Drivers keeping their navigation devices updated and following dynamic road updates will minimize potential disruptions. The flexibility required by Istanbul traffic during such events and the need for careful planning are emphasized in every setting. A call is being made to drivers for patience and sensitivity to ensure the organization proceeds smoothly. It is known that traffic teams will work intensively in the region to facilitate traffic flow.
