It is quite possible that the Mumbai Trans Harbor Sealink (MTHL), which connects South Mumbai to Navi Mumbai, will adopt the Open Road Tolling (ORT) system, which is now in use in international cities like Singapore.
Mumbai Metropolitan Region Development Authority (MMRDA) commissioner SVR Srinivas said on January 11 that they are researching the technology. The absence of boom barrier system in open road toll technology would prevent lines from forming on the sea bridge. He said it would offer smooth commuting without any delay.
Benefits of ORT include better gas mileage, safer and cheaper travel, less congestion and less vehicle exhaust emissions. With MTHL, commuters can travel from South Mumbai to Navi Mumbai and vice versa without signals in 20 minutes.
By using ORT, tolls are collected without the need for traditional toll booths. Instead, the ORT functions as a toll booth that can electronically recognize moving vehicles and collect the toll.
The total bridge is approximately 22 km long which includes 16.5 km of sea bridge and 5.5 km of culverts on land at both ends of the bridge. The link has interchanges with Sewri and NH-4B in Mumbai at Shivaji Nagar and Chirle, Navi Mumbai.
