Protesters have been cautioned against barricading Mombasa Road in quest to have their grievances addressed.
Mlolongo Assistant County Commissioner David Mukung said various groups should use legal procedures whenever aggrieved instead of taking their anger to Mombasa Road.
Mukung spoke in Mlolongo town, Machakos County after police fired tear gas to disperse demonstrating track drivers on Tuesday.
Police intervened after the drivers, who operate in Mavoko quarries, used their trucks to barricade the busy Nairobi-Mombasa Highway at kapa and All Park areas.
The truck drivers demonstrated as they were denied access to the quarries.
Their action led to a heavy traffic snarl up that lasted close to two hours.
Some of the drivers who spoke on condition of anonymity said there are no roads leading to the quarries, most of which are located in Mlolongo, Muthwani and Kinanie wards of Mavoko sub-county.
They said the owners of the property they pass through on the way to the quarries had closed them.
"We need roads since we have no access to the quarries. Those whose land we passed through [are also] charging lots of money to allow the trucks access."
"Their complaints are genuine but they should seek redress from concerned authorities. We shall not condone the barricading of Mombasa Road," Mukung said.
