Protesters have stepped up their efforts to ensure Saturday repeat presidential election, as ordered by the electoral commission in Nyanza, does not take place in Migori County.
After staging demos all day Thursday, unknown demonstrators spent the night blocking entry and exit from the border county via road.
They went as far as welding girders across the main highway linking Migori town to Tanzania, in an attempt to prevent any delivery of voting material in the county.
In an unprecedented barricade, the youths ganged up and carried a wielding machine where they soldered the barriers, often used on the shoulders of the road to prevent cars from veering off.
Migori town, which neighbours Tanzania lies on the southern side of Nyanza, only has two main highways leading to and from the town.
The protesters also blocked the main highway from Kisii through Awendo, meaning transport was halted.
As the police battled to clear the barricades on Friday, the demosntrators continued to erect more with boulders.
They forced pedestrians to help carry the stones to be allowed to pass.
