Kilometric points need to be re-mapped here; the Szprotawa bypass is numbered from km 0 to at least 3.7 (source: GDDKiA via dane.gov.pl)

Milestones from here onward (southwestbound) seem to have changed

Is this really a road milestone? If it refers to the railway, it should have a railway= rather than a highway= tag

There’s a bike path south of DK16 which runs parallel to it. Its western end is roughly where the last houses are; it is briefly interrupted at the railway crossing (bikes use a brief stretch of road there) and resumes afterwards; no idea how far it extends to the east. Judging from OpenStreetCam imagery, it seems to have been built only in summer 2017.
