MAAI MAHIU ROAD
This comes a day after raging flash floods washed away a section of the Maai Mahiu-Narok Road paralysing transport for more than 24 hours.
However, by today evening, engineers had completed repairing the section of the road.
An official from the China Communications Construction Company termed the repaired section as "safe", with motorists allowed to use the busy route.
The company was contracted to repair the washed away section that caused heavy traffic snarl up on the busy highway.
Road engineers involved in repairing the road in the past have blamed the geological set up around the Maai Mahiu area to the occasional damage of the busy road.

On Tuesday, a Form Two student at Governor Secondary School in Maai Mahiu drowned after she was swept away by the raging water.
She was among a group of five others who attempted to cross over a flooded gully when the incident occurred.
A tractor driver who also survived the deluge managed to save four of the students.
"She was swept downstream and efforts to rescue her, proved futile," a resident, Nevas Chege, said.
Her parents and schoolmates were inconsolable after her body was found on Wednesday morning.
Two of the victims were rushed to the Naivasha Sub-County hospital where they are still undergoing treatment.
Area leaders among them Naivasha MP Jayne Kihara visited the institution today to condole with the teachers and students.
In Kiambu County, a five storey building that has been under construction for the last eight months collapsed at Juja following the heavy rains.
The building collapsed at around 11pm on Wednesday but there were no casualties reported.
The family living behind the building said they were woken up by the thunderous sound.
"We were asleep when we suddenly heard a thunderous sound of something huge falling.
"On stepping out of bed, I was met with a huge cloud of dust and some noise outside since some neighbours had already broken into our gate in an attempt to rescue us thinking we had been hurt," the resident said.
His neighbours led by James Kariuki said that the building whose construction begun mid last year had been showing signs of collapse.
"We have had many incidents of stones falling from the building. Some cracks could be seen from outside but the owner kept reinforcing the building using planks of wood," Kariuki said.
Mr Josiah Anunda, a resident, said that the building was set to host students from Jomo Kenyatta University of Agriculture and Technology, some of whom are said to have already booked the single rooms that were set to be occupied from next month.
National Construction Authority regional coordinator Eric Miseda said preliminary investigations showed that construction of the building had been going on illegally at night despite having been stopped twice over safety concerns.
"It is obvious that the building was constructed hastily and at night and using substandard material.
"Two closure notices had been issued but the owner ignored them. That coupled with the ongoing rains are the reasons for the entire collapse of the building," Mr Miseda said.
Kiambu County commissioner Wilson Wanyaga urged members of the public who were milling around the debris to avoid the area until the debris has been cleared.
He added that the police were searching for the owner of the building who will be charged with flouting building regulations, negligence and loss of lives if found answerable over the death of two of his workers last year.
Reports indicated that the two workers died after building stones fell on them from a crane that had been lifting them to an upper floor late last year.

The rainfall pouring in Mount Kenya region has also rendered many weather roads in the county impassable.
Today, the National Transport and Safety Authority warned the public to be extra vigilant on the vulnerable roads.
Major roads and highways such as Mombasa Road, Uhuru Highway, Jogoo Road and Limuru Road were also adversely affected.
"We caution road users that after the recent dry weather there is a build up of dirt and soil deposits on the road, when this mixes up with the rain water it increases the risk of a skid," NTSA director general Francis Meja said in a statement.
The NTSA has also asked pedestrians to use designated crossing points to avoid unnecessary risks.
