Several apps only route this section of Shumack Street correctly northbound. If you try to route southbound they behave as if it is one way north and route around this section using adjacent roads. It is definitely a two way road, both northbound and southbound. I wonder if the turning lanes at the north end of Shumack St or the dual carriage part of Shumack Street to the south have one way northbound attributes that falsely cover this part of the road.
