Protesters blocked the NH 31A at some places in the district, official sources said today.
The 92 km long NH 31A connects Sevoke in Darjeeling district to Gangtok and is considered the lifeline of Sikkim. Around 30 km of the highway passes through West Bengal.
Sikkim government sources in Gangtok said they had yesterday requested their West Bengal counterpart to provide security to vehicles passing through Darjeeling district in NH 31A in view of the GJM agitation.
