At the time the bridge was built, it was actually to bypass US 50 out of downtown Olathe and off of Kansas City Road/Santa Fe Drive and then on to Quivira (at 87th).
It hooked into what became the northbound lanes of I-35 later and the route went over the older of the two (overhead) bridges at 75th street.
At the time 50 (going west) split into 50N & 50S at US 59. Later 50 N became US 56 and 50 followed I-35 until it split off west of Ottawa.
