Lam Dong (VNS/VNA) - Lam Dong province’s Department of Transport has authorised the temporary resumption of most traffic on Prenn Pass, located in Da Lat since December 5 morning following a 20-hour closure to deal with landslides.
Specific time windows have been set for all vehicles excluding lorries to use Prenn Pass: on December 5 from 9am to 10pm and on December 6 and December 7 from 5am to 10pm.
Outside these periods, all travellers must comply with Notice 474/TB-SXD issued earlier by the Department of Construction, which bans all access to the landslide-affected section until further notice to allow repair work to proceed.
Traffic heading to and from Da Lat is being redirected along three routes.
Mimosa Pass remains open to two-way traffic for all types of vehicles.
Sacom - Tuyen Lam Pass is open to all vehicles except lorries, with traffic from the Lien Khuong Expressway turning left into Sacom - Tuyen Lam to reach Da Lat centre, and vice versa.
Ta Nung Pass on provincial Road 725 is also open to two-way traffic for all vehicles.
It was reported that intense overnight rain on December 3 triggered landslides along several mountain roads leading into Da Lat, rendering them impassable.
Prenn Pass, the main gateway into Da Lat, was particularly affected, with a severe landslide occurring at midday on December 4.
Provincial construction authorities said that heavy rain and storm conditions remain complex and unpredictable, while repair teams continue work on the pass.
The department has urged residents and motorists to exercise extreme caution when travelling on Prenn Pass during the prescribed time windows, remain alert to road conditions and respond swiftly to any emerging hazards.
Drivers are advised to slow down, observe traffic signs and comply with temporary traffic management measures at active construction points.
The department has also asked the provincial traffic police and local authorities to deploy patrols to maintain smooth and safe traffic flow during the repair period.
Project Management Unit 1 has been instructed to ensure contractors regularly inspect the site, install proper road signage in line with approved traffic management plans and deploy staff to guide vehicles through the affected areas./.
