Istanbul authorities are changing traffic arrangements for bridge reinforcement and renovation work. The Istanbul Metropolitan Municipality (IBB) announced that some roads will be temporarily closed to traffic because of work at two separate locations in Bakirkoy, a district on the city’s European side.

As part of reinforcement work on the D-100 Incirli Bridge in Bakirkoy, the Topkapi-bound service road, a side road running parallel to the D-100 highway, will be closed to traffic at 11:00 p.m. local time (8:00 p.m. GMT) on Sunday, Nov. 8.

Service road traffic will be diverted onto the D-100 for 15 days. The Topkapi-bound service road is scheduled to reopen with a single lane on Monday, Nov. 23.

Work on the bridge is expected to be completed on Wednesday, Dec. 23, when the road will fully reopen to traffic.

Bridge over Marmaray line to be renovated in 180 days

The bridge carrying Adnan Kahveci Boulevard over the Marmaray line in Bakirkoy will also be renovated. Marmaray is a commuter rail line that runs through a tunnel under the Bosphorus, linking the European and Asian sides of Istanbul.

As part of the work, Adnan Kahveci Boulevard, Beyaz Lale Street and Dumlupinar Street will be closed to vehicle traffic in both directions from 12:00 a.m. local time on Sunday, Nov. 8.

Under a decision by the Transportation and Traffic Commission, vehicles will be redirected via Dr. Remzi Kazancigil Street, Rauf Orbay Street, and Kilitbahir Street.

Pedestrians will cross via a temporary ramp to be built next to the bridge.

The existing bridge, which has reached the end of its structural life, will be removed and replaced with a new three-span bridge that is 60 meters long (197 feet). and 30 meters wide. The renovation is planned to take 180 days.

The reinforcement work at Incirli Bridge and the renovation of the bridge over the Marmaray line will follow different schedules.
