In the days before there was a “New route 13,” all westbound vehicle traffic left Marion by way of a two-laned paved road we now call “Old 13.”
Where this Route 13 was intersected by Route 148, which came south from Herrin, the westbound road split in two. One lane veered off toward the north in a curving path shaped somewhat like the letter “Y.” This type of interchange was therefore commonly known as “the wye.”
South of this wye, the sprawling and secret Illinois Ordnance Plant was built. The plant manufactured ammunition for the Allies during World War II. The route 13/148 intersection was its main entrance. Older residents can still remember the security police gatehouse and barriers standing across the road there, during the 1940’s.
Today, the ammunition factory grounds, once known as “Ordill,” have been incorporated into the Crab Orchard Wildlife Refuge.
