Sen was travelling by road from Santiniketan to Kolkata en route to New Delhi, police said.
Sen requested Congress workers to make way for his car but the party workers led by its Burdwan rural unit leader Azizul Haq Mondal lay down on the highway to stop the vehicle.
Requests by the police on Sen's behalf also went unheeded.
Burdwan police station inspector-in-charge Dilip Gangopadhyay said the traffic build-up due to the blocakde was so large that Sen could not be taken out of it through another route and he was allowed to cross only at 1 pm after the agitators withdrew.
The party held state-wide blockade on Wednesday to protest the alleged false FIRs against Union Minister Adhir Ranjan Chowdhury and 1200 others in Barhampore for vandalising the Murshidabad district magistrate's office last week.
Burdwan(WB): Nobel laureate Amartya Sen was stuck for about 15 minutes today on NH-2 near here in a blockade by Congress workers.
