Chiyambi cha malonda
Urban flyover ndi mtundu wa zomangamanga zomwe zimathandiza oyenda pansi kuwoloka msewu m'mizinda yamakono. Kumanga kwa overpass kumatha kulekanitsa kwathunthu oyenda pansi ndi magalimoto pamsewu, ndikuwonetsetsa kuyenda bwino kwa magalimoto ndi chitetezo cha oyenda pansi.
Ubwino wa mankhwala
1. Mtengo wotsika
2. maonekedwe okongola
3.zowonjezera zowala
4.msonkhano wachangu
5.kusinthana
6.detachable
7. moyo wautali
Ntchito zamalonda
Kudutsa kumazindikira kulekanitsa kwathunthu kwa oyenda pansi ndi kuyenda kwa magalimoto, chitetezo cha oyenda pansi chimakhala chotsimikizika, ndipo kuyenda kwa magalimoto kumakhala kosavuta. Komabe, mtengo wa overpass ndi wotsika ndipo nthawi yomanga ndi yochepa, ndipo sizidzakhudza mphamvu yonyamula katundu wa msewu. Tsopano misewu ikuluikulu yodutsa m'mizinda ili ndi ma elevator, omwe ndi osavuta kugwiritsa ntchito okalamba.
