The invention discloses a safe and stable suspension bridge and a construction technology thereof. The construction technology specifically includes the following steps that 1, firstly, the whole suspension bridge is divided into a steel arch foot bearing platform, a steel mixing joint section, a pure steel structure section, a cross beam section and a tower crown decoration section according tothe different structure composition; 2, embedded parts are set in a designated position, and pouring is conducted on the embedded parts to prepare the steel arch foot bearing platform; 3, the steel mixing joint section is constructed on the steel arch foot bearing platform; 4, after the steel mixing joint section is constructed, the pure steel structure section is constructed; 5, the cross beam section is constructed on the pure steel structure section, and fixation is then conducted; 6, finally, the tower crown decoration section is built and fixed on the upper portion of the cross beam section. On the basis that the construction quality is guaranteed, the construction technology of the bridge is optimized, the whole construction process is relatively simple, the whole construction speedis increased and the construction period is shortened.
