Bitewe no kugabanya uburebure no kwagura uburebure, ubwuzuzanye bwa tunel burigihe ningorabahizi kubakoresha.Ibiranga umuyoboro bigabanya uburyo bwo gutanga ubwishingizi.Imiyoboro ya gari ya moshi cyangwa gari ya moshi isanzwe iba ifunganye, kandi hejuru hejuru;mugihe umuhanda wumuhanda ukunda kugira icyumba kinini kandi cyagutse.Mubisanzwe, tunel ikoreshwa gusa mubihe bimwe;Kubwibyo, guhinduka kwa porogaramu biranga, igihe cyo gushyira mubikorwa byihuse, hamwe nigiciro gito byatumye repetater ihitamo neza nkigisubizo cyo gukwirakwiza ibimenyetso bya tunnel.
Bitewe nubutaka bwa tunnel, biragoye cyane kubimenyetso byasohotse kuri sitasiyo fatizo kugenda inzira yose inyuze kumurongo keretse sitasiyo fatizo igenewe gukwirakwizwa.Kubwibyo, tunnel nyinshi ifite ikibazo cyo gukwirakwiza ibimenyetso nabi.Usibye gukoresha sitasiyo shingiro kubwikwirakwizwa rya tunnel, Fibre Optic Repeater nigisubizo cyiza cyo gukwirakwiza umuyoboro, mugihe High Power Repeater nayo ishobora gushyirwa mubikorwa kugirango tunonosore ibimenyetso muri tunnel.
