Imagwira ntchito pamapaipi achitsulo opangidwa ndi ulusi wotchulidwa mu AS 1722.1, ndi mapaipi achitsulo osalala kuchokera ku DN 8 kupita ku DN 150.
Makulidwe atatu a khoma la chitoliro chachitsulo amatchulidwanso, opepuka, apakati, ndi olemera.
AS 1074 machubu amatha kupangidwa ndi mwinaopanda msokokapena njira zowotcherera, ndi njira yowotcherera nthawi zambiriERW.
Mitundu itatu ya zitoliro zimaphatikizidwira: zomveka, zopindika, ndi zoyambira.
