The closure forms part of the ongoing Bengaluru Metro Phase-2A (Blue Line) project, which aims to connect Central Silk Board to K R Puram, covering 19.75 kilometres with 13 elevated stations. The Marathahalli bridge, a key junction along this route, will be inaccessible, and motorists are advised to plan alternative routes in advance to avoid delays.
