Deputy Chief Minister Udhayanidhi Stalin inaugurated the limited-use vehicular subway at Radha Nagar in Chromepet on Wednesday. The subway costs ₹31.62 crore and was built as a replacement for level crossing 27. It will serve residents of Radha Nagar, Zameen Pallavaram, Postal Nagar, Nemilichery, Nanmangalam, and Medavakkam. Minister for MSME T.M. Anbarasan, MLAs E. Karunanidhi, S.R. Raja, and Chenalpattu district Collector D. Sneha also attended the event. The subway project dates back to 2006. Initially planned as a pedestrian-only path, it aimed to help East Chromepet residents reach the Grand Southern Trunk (GST) Road. The original cost was ₹17.65 crore. However, after requests by Radha Nagar Main Road residents in 2016, the Highways department upgraded it to a limited-use subway. Activist V. Santhanam said, "We held many protests urging the government to finish the project. We kept pushing for its completion. By 2012, the railways had completed their work to construct the structure under the tracks. It has taken so many years to complete an important infrastructure project. The gate will however remain open for bigger vehicles to cross." The subway measures 329 meters in length and 5.5 meters in width. Separate service bridges on the GST Road side and Radha Nagar side provide easy access to Chromepet railway station. Staircases connect the subway to the railway station from both sides. Height gauges on both ends keep heavy vehicles out. LED lights illuminate the retaining walls of the subway. The new subway is set to ease traffic and improve connectivity in this crowded area.
