The contractor did a brilliant job but the designers never thought of joining the highway from service lane or exiting the highway to service lane. There must be enough space to accelerate before joining the highway.

it was designed by indian engineers. The roads ministry need to fund another redesign especially for safety issues on the service lanes.

I don't use Thika Rd frequently, but few times that I have, my biggest problem was the signage more than anything else.

Most entry/exit signage were either too soon, or too late for one to take action.

Speed bump signs placed 2 metres to the rumble strips, which are 1 metre from the bumps. .....SMH. ...

Exits prior to congested underpasses~At times you want to go beyond the underpass then exit. ....

Very tiny drainage holes on the drifts. ..

And my favourtite are the Orange warning signs placed between the service and lane 1(Leftmost lane),

- "THROUGH TRAFFIC MERGE RIGHT'

Am always perplexed who is it addressed to, guys on The service lanes or Lane 1?

Does this imply that engineers at the roads ministry don't drive?..otherwise they should have noted these shortcomings..

@chaka, its not the kenyan engineers who designed the road. its an indian engineering consultancy firm.
For kenyan engineers to alter the design, the contract btn kenya and the indian engineers need to be altered.

@4Arch,
What you are saying is that for these kinds of projects the "client: i.e Kenya Government cannot make any recommendations before project rollout?

True. I also find some sections of the service lanes too narrow, its a nightmare to overtake a bus/lorry

the client i.e Kenya is represented by ps ministry of roads. His office should have seen this and pointed out to the consultants to amend design but it looks like the design phase was not properly taken care of. The experience of the engineering consultancy should be able toiron out these issues. Looks like the vetting process for consultancy didnt get the best engineers. The indians maybe did not have experience with such projects. The chinese contractors, hovewer, did a perfect job .

The reason kenya was using international consultants is coz we dont have engineers with such experience so we cnt fault ps ministry of roads for not seeing this. We can fault the selection process since they should have given us engineers with previous experience on such roads.
