In QGIS, the shapefiles don't align. The freeway layer has a warning question mark saying "no CRS set for layer," however once I set the CRS to match the city boundaries layers (WGS 84 epsg:4326), nothing changes. I "save feature as" shapefile with the same CRS and the imported result is still misaligned with the boundaries.
I tried to export the file again, setting the extent to match the city boundaries, but then it just exports with 0 features.
How can I get the files to align? Specifically, how do I get a file with no CRS to align with another if simply setting the CRS and re-importing does not work?
