The road blockade began at 11 am and continued till 4 pm.
Farmers holding black flags and wearing black armbands and some women protesters with black 'dupattas' shouted slogans against the BJP-led government for not acceding to their demands.
Protesters in Sonipat and Jhajjar districts and some other places brought their tractor-trolleys and other vehicles and parked them in the middle of the KMP Expressway in some stretches.
The Haryana Police had made arrangements for traffic diversions and deployed adequate personnel.
The call for blocking the expressway was given by the Samyukta Kisan Morcha, an umbrella body of protesting farmer unions which is spearheading the agitation against the legislations.
