Ravi Dutt Sector-2, IT Road Kapoorthala Lucknow- 226001 Date: 27/08/2022 The Editor The Hindu Lucknow Subject: Urgent need for road repairs in Sector-2, IT Road Sir, I am writing to bring attention to the deteriorating condition of the roads in Sector-2, Kapoorthala. Despite repeated appeals to the local municipality, no action has been taken. The roads have been virtually impassable for the last month, posing a severe inconvenience to all local residents. Heavy rains have caused significant damage, making travel dangerous—especially at night. With debris lining the roads and narrow passage, accidents have become frequent. I urge you to highlight this issue in your newspaper to pressure the authorities to begin urgent repairs. Thank you for your attention to this serious matter. Yours sincerely, GANESH (Resident)
