We are doing a design study of the Mombasa Gate Bridge at KeNHA HQs currently. The bridge is 1.3km long cable stayed and will have two interchanges and a connecting road of 8km. This makes it longer than any other bridge in East Africa at the moment. I'll post mpre details and drawings when we are done.

1. Kigamboni bridge is a harp bridge while Mombasa Gate is a semi fan bridge.
2. Kigamboni bridge is a single tower while Mombasa Gate bridge is an A-shape tower bridge
3. Kigamboni bridge has one 3-leg directional, 2-level interchange connected to it on one side while Mombasa Gate bridge has a 3-leg directional, 3-levelinterchange connected on one side and a Trumpet intechange on the other.
Google the meaning of the terms or come for classes you idiot.
The two bridges are like sea and sky, the only similarity is that they are both cable-stayed bridges.
(PS........Mombasa Gate bridge is double the length of Kigamboni bridge)

Geza Ulole huyo NairobiWalker ni engineer mwenzako kwa hivyo unapoongea ukumbuke hilo. Mimi sielewi mambo ya engineering lakini yeye anaelewa so tulia akupe maelezo kamili kuhusu daraja hili.

Could you kindly explain to us the difference between a harp bridge and a semi fan bridge?

I prefer suspension bridge,
Hizi cable bridges Ni sura mbaya sana.

A harp bridge, the cables are nearly parallel
A fan bridge, the cables converge to one point at the top
A semi-fan bridge, the cables converge to the top but not to a single point
A mono bridge has only one cable
A star bridge, the cables converge at the bottom
A fan bridge is structurally superior to the rest because it minimizes moments applied to the tower but a semi-fan bridge is more practical where many cables are involved.

Suspension bridges are quickly running out of fashion due to their expensive construction costs in comparison to Cable-stayed bridges. The suspension main cables are normally huge and expensive and they also require an anchor which is expensive to construct especially in loose coastal soils and require more space and there's the danger of self-induced vibration like in the Tacoma Narrows Bridge collapse in the video below. However, for spans over 1000m, Suspension bridges are the better option.

3 years umeitoa mat*koni au wapi? Huu uzi ulianzishwa Dec 2019 yaani almost January 2020. So hata miaka miwili bado haijafika. It's just 1 year and 4 months since the thread was started.

Wacha ujinga suala la Likoni bridge lina miaka zaidi ya tano! Mnachofanya ni kufungua nyuzi kila siku!

Sawa basi. Wakati huo design haikuwa imekamilika. Sasa hivi design imekamilika na engineers wa Kenha wanaipitia ili kuielewa na kuiapprove. So very soon ujenzi utaanza.
