problem with Thika road is in the CBD
1.koja round about is one of this
2.make Kirinyaga road a one way road draining thika road
3.Moi avenues is also one one big mess because of the matatu stages
move all stages to the small roads like the accra road up country stage,
Githurai stage causes all the jam on racecourse,
4Those bumps on thika road are a great put off.
5.The underpasses like the ones of TRM,Kimbo, githurai,Kahawa are sometimes very messy, I don't know why.

Yes indeed you are right. I read somewhere (sina link) that Kenyans import 10,000 cars per month or something of the sorts. After some thought, i concur with fellow wazuans who have opined that hefty charges be introduced to deter people from using personal cars in CBD.

The current status of Thika road is really wanting, by 6am Jam is building at Safari park. Every body want to leave early, we need trains, more roads, more trafic cops, footbridges etc before the outering road is done and all the vehicles pour to the superhighway taking us back to where we were when it was a two lanes...

Since all this may take eternity, why then dont we make easy to get to CBD for now, at least we see how it can work. During rush hrs, all the private vehicles should use the service lane (they are 2 lanes anyway) while the PSV use the superhighway itself.(There are 4 lanes, one can cater for stages at different points, that way thousands of commuters will be getting to town faster and cheaper.....creating an incentive for PSV while not limiting private vehicles access to CBD..........

You are making a grave mistake to assume that kenyans are rational

Why are we assuming gova has the local mwananchi at heart? If you use PSV the govt has ni business with you except of course the fact that you will still vote in your local idiot come the next election. We need these private cars in the CBD for parking fees to kanjo. Instead of thinking of decongesting the city, CCN wants to construct a highrise car park at the sunken car park right in the CBD. We need those second hand vehicle imports so that we can collect more tax from the importers, we need also to import and use more fuel oil so that we can collect taxes from it and also enrich the few who own oil marketing companies. We need to constantly construct and expand roads around Nbi to enrich our contractor friends. We also need to make sure the rail transport is dead to ensure business for our trucking companies. Finally we need to laugh at our neighbors Tz and Ethipia for investing in bus rapist transport and light commuter rail hahaha those communists!!!

I think dealing with this one as though it is a thika road problem is what is myopic. This is a Nairobi city problem. Mombasa has it's fair share too but that's for another day.
There are simply too many cars coming into and out of the city during the same 2-3 hours durations every other work day. This is the crux of it.
How do you deal with too many cars? Either have limitless lanes into and within the city or do the only thing which will work: DECONGEST.
In my view, decongesting the city can be done by:
*Providing a working public transport infrastructure (so people can volunteer to use PSV not private cars)
*Provide infrastructure for other means of transport e.g cyclists
*Decentralise the economy. Move industries, major employers who do not need to be in CBD out of the city. This works magic on cost of living too.
*Discourage use of private cars by a)raising the parking fee to close to 11.5GBP for street level parking. b)Reduce street parking slots and hence expand roads for better intra-city circulation.
Note the last point hardly works where the first 2 are not in place.

@Speculz, the bottom of this approach is to discourage use of private vehicles at peak hours. To understand better the genesis of jam in kenya or thika superhighway is down to specifically 3 things, 1. pple taking one route (CBD), 2. pple using same mode (road), & 3. pple travelling at the same time (rush hrs). to fully address this it calls for a holistic approach with alot of investment which may not be available. and after all this investment its a vicious cycle as transport capacity is expanded more pple shift to those areas (good case of thika superhighway).dilema is, its hard to have jam free roads, and since we Kanju and others cant agree to chase away private vehicles from cbd due to interest, then we can only limit their number on the roads, by designating roads for PSV and private expecting the private to suffer more in rush hr. More investor trho govt or PPP shud come in to provide decent PSV system..........

While go.ke is busy setting up committees after committees to beg capitalists (running public transport)who will do anything to ensure a chaotic public transport system remains, the communists are doing less talk and actually implementing. Most road reserves have also been grabbed in KE by the capitalists......damned capitalism. A retired mzee once confided in me that the original Nairobi plan had a city tram/train system running along Ngongroad through Kenyatta avenue with the current imenti house supposed to be a rail station(mwisho wa gari)...the train was supposedly to go underground once it reached community all through to Imenti house

and there is no problem with those who have to use their cars. Let them use them on Thicker Rd or any other rd so long as there is a premium apart from normal vehicle running expenses charged!

Sorry I haven't read all the comments, but if Thika rd expansion was a mistake, then the original construction itself must have been the bigger mistake??
