Haridwar, May 23 -- A traffic diversion plan has been put in place for slope stabilisation works on Phase 4 of the Delhi-Dehradun Economic Corridor (Ganeshpur-Dehradun section) till June 8, as the authorities move ahead with safety enhancement measures along the mountainous stretch, officials said on Thursday. The project, being executed by the National Highways Authority of India (NHAI), is aimed at strengthening vulnerable hill slopes and reducing the risk of landslides and rockfalls along the highway. The work began on Friday, after receipt of necessary forest and environmental clearances, and is targeted for completion before the onset of the monsoon season. Officials said additional forest land has been diverted for the project, and the proposed works will include scaling of hill slopes and removal of loose debris along the carriageway. To ensure commuter safety during execution, a diversion will be enforced on an approximately 1.250 km stretch of the highway. The diversion arrangement will remain in effect from May 22 to June 8, while the remaining sections of the corridor will continue to remain open for regular vehicular movement. Traffic management teams and flagmen will be deployed round-the-clock to guide commuters and maintain smooth flow. For vehicles heading towards Dehradun, traffic will be diverted from the Left Hand Side (LHS) carriageway to the Right Hand Side (RHS) carriageway . Vehicles will continue on the RHS for about 1.250 km before merging back onto the LHS carriageway, near the Daat Kali Tunnel. For traffic moving towards Delhi and Saharanpur, vehicles will exit after the Daat Kali Tunnel (RHS) and be diverted onto the old highway section. After covering around 1.3 km on the old route, traffic will rejoin the main corridor. The Ganeshpur-Dehradun stretch of the corridor passes through difficult mountainous terrain where extensive hill cutting was earlier undertaken for widening. Officials said precautionary measures have already been implemented to minimise the risk of falling debris affecting traffic....
