Ibhulorho yentsimbi yentsimbi yinkqubo yesakhiwo phakathi kweepali kunye nee-arches. Isakhiwo apho i-bent ye-beam ephezulu kunye nekholamu ephantsi yoxinzelelo idibene kunye. Ngenxa yoxhulumaniso oluqinileyo phakathi kwe-beam kunye nekholomu, i-beam ikhutshwe ngenxa yokuqina kwe-flexural yekholomu. Inkqubo iyonke yinkqubo yokugoba ucinezelo kunye nesakhiwo sokutyhala.
Ngokuqhelekileyo isetyenziselwa iibhulorho zasezidolophini okanye i-viaducts yendlela ephezulu kunye ne-overpasses enezipani ezincinci; ikhonkrithi eyomeleziweyo ephakathi kunye nencinci; Ikhonkrithi eyomeleziweyo egxininisiweyo; isithuba esiphakathi nesincinci izakhelo eziqinileyo zomlenze othe tye (uhlobo lwesango) kunye nezakhelo eziqinileyo zomlenze; isakhelo esikhulu seSpani esimile okwe-T, isakhelo esiqinileyo esiqhubekayo.
