[closed] I lack the experience to do this. May I get help with routing please?

Hello, North of the Arkansas River is North Little Rock (NLR) and in part my issue. I attempt to edit US 70B in Little Rock (south of the Arkansas River). The route for US 70B used to be on South University Avenue before partially changing. This is confusing. In NLR is the intersection of the Broadway Bridge/Broadway Street and West Broadway Street. I tried to change the former route to be I 30, mile marker 128, Exit 129, north on I 430, Exit 1, northeast on Stagecoach Road, Continue on Colonel Glenn Road, Continue on Asher Avenue, (at the fork but worded differently) right on West Roosevelt Road, left on Broadway Street (in Little Rock), to the Broadway Bridge. That is my idea. If I could make that work, I would create a westbound version. The route is almost the same. I 30 is US 70. However, this begins at or near the Broadway Bridge in NLR. I attempted to begin on I 30 at 128. The route appears to do what it wants before going back to NLR. Might I please receive some help? I removed US 70B from every other place that it should not have been in Little Rock. I 30 does run into NLR before reaching I 40. This should help. https://www.openstreetmap.org/edit#map=16/34.7669/-92.1974
