Road bridges Thane road bridge is the oldest bridge built over this creek. This bridge connects Thane and Kalwa. The old road bridge is no longer in use and has been superseded by the new parallel bridge. Vashi & Airoli road bridge connects two sister cities of Mumbai and Navi Mumbai. These bridges are very important bridges as it carries heavy traffic between Mumbai, Navi Mumbai and towards Pune. Being one of the busiest routes in India, the bridge provides a shorter route to Pune. A parallel trans-harbour road link is planned to connect Mumbai's two ports as well as to reduce rush on this bridge.
