Utawala residents on Wednesday lit bonfires in protest over sand trucks which they said mess up roads in the area.
They also complained of pollution from dust emitted by the trucks as they transport building materials.
One of the protesters said the trucks operate day and night, a situation she said causes them sleepless nights.
The woman, a landlord in the area, said all the tenants who rented her house have left because the dust.
"We have the right in this country. The dust is too much. This road is not for lorries and they should desist from using this route."
The trucks reportedly use the road to avoid a weighbridge at Mlolongo, a situation the locals said also exposes children to respiratory diseases.
"We have tried to talk to the area MCA but haven't seen any solutions. We are suffering. The former MCA tried to solve it but nothing happened," she said.
Victor Mochere, resident, said they have the right to demand for better infrastructures in the country.
"Do we need to protest in order for the government to provide amenities and build infrastructure? The state of roads in Utawala is pathetic," he said.
Kenya Red Cross advised motorists to be caution when using the road.
